Imām Muslim and the Guardians of Hadith: Preserving the Prophet’s Legacy

Introduction: A Labor of Love for the Prophet’s Teachings

How do we know what Prophet Muhammad ﷺ said and did over 1,400 years ago? How can Muslims today follow his example so long after his lifetime? The answer lies in the extraordinary efforts of scholars in early Islam who dedicated their lives to preserving his words. Imām Muslim ibn al-Ḥajjāj and other great hadith collectors were among these guardians of the Prophet’s legacy. They traveled vast distances, scrutinized every narrator’s honesty, and recorded tens of thousands of reports – all to ensure that authentic teachings of Prophet Muhammad ﷺ would reach us intact.

Their story is one of devotion, scholarship, and even what many consider divine help. This article will explore who these scholars were, how they preserved hadith (the sayings and actions of the Prophet), and why their work is so important for Muslims and curious non-Muslims alike. Along the way, we will introduce the science of hadith in simple terms and share wisdom from the Quran and Prophet Muhammad ﷺ about truthfulness and preserving knowledge.

“Whatever the Messenger gives you – take it; and whatever he forbids you – abstain.” (Quran 59:7)

The Quranic verse above highlights why Muslims care so much about hadith: God commands believers to follow the Prophet’s guidance. But to follow, one must first preserve and authenticate the Prophet’s teachings. Let’s see how the early Muslim scholars rose to this challenge.

What are Hadith and Why Do They Matter?

In Islam, a hadith is a piece of information about Prophet Muhammad ﷺ – for example, something he said, an action he did, or an approval he gave. While the Quran is the holy book of Islam, hadith serves as a key source of guidance for Muslims by explaining and applying Quranic teachings in daily life. The Prophet’s words and example teach Muslims everything from how to pray, to how to be honest in business, to how to show kindness to neighbors.

“Indeed, in the Messenger of Allah you have an excellent example for anyone whose hope is in Allah and the Last Day.” (Quran 33:21)

However, not every statement attributed to the Prophet is true – some could be mistakes or even fabrications spread in later times. That is why hadith science developed: to separate the accurate sayings from the false. The scholars who devoted themselves to collecting hadith did so out of love for the Prophet and a commitment to preserving the truth. They knew that following authentic teachings was essential for Islam to be practiced correctly.

To ensure authenticity, Muslim scholars established a unique method. They paid attention to the isnād, or chain of narrators, for each hadith – essentially a list naming each person who heard the saying and passed it on, from the Prophet’s time down to the scholar who recorded it. They developed strict criteria to judge each narrator’s trustworthiness and memory. If a chain had any weak links (such as an unknown or unreliable person), the hadith’s status would drop.

Hadith Grades in Simple Terms

Early Muslim scholars were amazingly meticulous. One early scholar, Ibn Sīrīn (from the generation after the Prophet’s Companions), famously said that in the earliest days people didn’t question hadith reports, “but when troubles arose, they said: Name your sources.” In other words, Muslims began to demand the isnād – the source chain – to ensure the teaching truly traced back to the Prophet and wasn’t just hearsay.

This rigorous approach created what Muslims often call the science of hadith, a whole field of study to authenticate reports. It was a labor of love and faith. The scholars believed they were fulfilling the Prophet’s own instructions to preserve knowledge and report it faithfully:

“May Allah brighten [the face of] a person who hears a hadith from me, memorizes it, and conveys it to others exactly as he heard it.” – Prophet Muhammad ﷺ (Sunan al-Tirmidhī)

The Early Efforts to Preserve Prophetic Teachings

Preserving the Prophet’s teachings began right away in the first generation of Islam. Prophet Muhammad ﷺ had many Companions who memorized his words and practiced his example. Some Companions, like ʿĀ’ishah (his wife) and Abū Hurayrah (a close companion), became well-known for narrating thousands of hadiths to others. In those early days, knowledge was preserved mostly through memorization and oral teaching. Arabia had a strong oral tradition, and people’s memories were honed to remember long reports. A few Companions also kept private written notes of hadith, but there was not yet a central written compilation while the Prophet was alive.

After the Prophet’s death in 632 CE, the Muslim community grew rapidly across the Middle East, North Africa, and beyond. With this growth came a greater need to compile and verify the Prophet’s teachings for new Muslims in faraway lands. Also, as time passed, the Companions began to pass away, so it became urgent to record their knowledge before it was lost. Unfortunately, a few individuals with bad intentions also began to fabricate hadiths for political or personal motives in later decades. This worried the sincere scholars, who responded by doubling down on verifying every report.

Thus, roughly within 100-200 years after the Prophet, scholars started traveling in search of hadith and writing them down in organized books. This era (8th–9th century CE, 2nd–3rd century AH) was the golden age of hadith compilation. Imagine scholars on foot or riding camels, journeying from city to city – from Madinah to Iraq to Syria to Egypt – just to hear a single authentic hadith from a reputable teacher! They would patiently collect these gems of wisdom “that fell from the lips of the Messenger of Allah”. Each hadith they heard, they would carefully record along with its chain of narrators.

As part of their methodology, hadith scholars developed biographies of narrators (a field called ʿilm al-rijāl, the “science of men”). They researched details like each person’s character, memory, and whether they actually met the person they claimed to learn hadith from. One scholar, Imam Yaḥyā ibn Maʿīn, was said to have evaluated thousands of narrators over his lifetime, setting standards for who could be trusted. This was all to uphold the truth, in line with the Quran’s command:

“O you who believe, if a troublemaker brings you news, verify it, lest you harm people out of ignorance and become regretful.” (Quran 49:6)

By the early 9th century (200+ years after the Prophet), the efforts of these scholars resulted in several reliable hadith compilations. Out of these, a collection of “six books” became especially famous in Sunni Islam, often called Al-Kutub as-Sitta (the Six Canonical Books). These six are the collections of Imām Bukhārī, Imām Muslim, Imām Abū Dāwūd, Imām al-Tirmidhī, Imām al-Nasā’ī, and Imām Ibn Mājah (we will meet each of them shortly). In later centuries, scholars universally recognized these works for their authenticity and importance, with the Ṣaḥīḥ of Bukhārī and the Ṣaḥīḥ of Muslim standing out as the most reliable. In fact, it became a saying that Sahīh al-Bukhārī is the most authentic book after the Quran, and the collection of Muslim is right next after Bukhari. This doesn’t mean the other collections aren’t valuable – they certainly are – but it underscores how rigorous Bukhari and Muslim were in choosing only the soundest hadith.

Before we focus on those six scholars, it’s worth mentioning one pioneer who came slightly earlier: Imām Mālik ibn Anas in Madinah. Imām Malik (93–179 AH) compiled al-Muwaṭṭa’, one of the oldest and most revered hadith collections. His book not only included Prophetic hadith but also the practices of the early Muslims in Madinah. Malik’s work was so respected that some later scholars even considered Al-Muwaṭṭa’ as one of the six canons in place of Ibn Mājah’s book. He was famously devoted to teaching in the Prophet’s city (Madinah), earning titles like “Imām of the Abode of Emigration (Madinah)” and “Knowledgeable Scholar of Madinah”. Malik rarely left Madinah (except for pilgrimage), demonstrating that seeking knowledge could happen by welcoming students from all over to come to him, whereas others roamed widely. His contribution set the stage for the scholars who followed.

Meet the Hadith Heroes: Imām Muslim and Other Major Collectors

By the third Islamic century, the science of hadith had matured, and several towering figures emerged who authored the collections that Muslims still study today. Let’s introduce the most prominent hadith collectors and learn about their lives and works. Each of these scholars had unique qualities, but all shared one goal: preserving the authentic teachings of Prophet Muhammad ﷺ.

These are the renowned Six Collectors of Sunni hadith canon, plus Imam Malik before them. We should also acknowledge Imām Aḥmad ibn Ḥanbal (164–241 AH, from Baghdad), who was a teacher to Abū Dāwūd and others. Imam Ahmad compiled the Musnad Ahmad, a massive collection of around 30,000 hadith arranged by Companion narrator. While not one of the “six books,” it is a treasure trove that influenced later scholars and shows the same devotion to preserving every possible word of the Prophet.

Their Devotion and Miraculous Feats

Each of these scholars exhibited almost super-human dedication. Their biographies are filled with inspiring (and sometimes astounding) anecdotes. We’ve already mentioned a few – like Imam Bukhari’s photographic memory that allowed him to recite 15,000 hadith from recall to correct his friends’ notes, or Imam Muslim’s all-night research session that cost him his life. Here are a couple more glimpses into their remarkable lives:

In the eyes of later Muslims, the success of these scholars in preserving Sahih (authentic) hadith is nothing short of a miracle and a fulfillment of Allah’s promise to preserve His guidance. Many Sunni scholars opined that the preservation of hadith and Sunnah is included in the Quranic promise: “Indeed, We have sent down the Reminder (Message), and indeed We will guard it.” (Quran 15:9). While this verse is primarily about the Quran, the Reminder (dhikr) can be understood to encompass the Prophet’s example as well, since Allah ensured that the means to understand and apply the Quran (i.e. the Sunnah) would also be safeguarded.

The universal acceptance of books like Bukhari’s and Muslim’s is itself seen as a sign of divine favor. Imām al-Nawawī (a great 13th-century scholar) wrote, “The entire ummah (Muslim community) is unanimous that Sahih al-Bukhari and Sahih Muslim are authentic, and it is obligatory to use their hadith as proof.”. And the renowned scholar Ibn Taymiyyah stated, “There is no book beneath the sky more sound than Bukhari and Muslim, after the Quran.”. Such praise from later scholars shows the level of trust these collections earned.

Sunni Scholarship on Hadith: Classical and Contemporary Views

The work of hadith preservation did not stop with the Six Imams – it continued as later scholars wrote commentaries, summarized hadith collections, and further refined the principles of authentication. Classical scholars like Imām al-Nawawī and Ibn Ḥajar al-ʿAsqalānī stand out for their contributions:

Fast forward to modern times, and you will find that interest in hadith remains vibrant. Contemporary Sunni scholars and speakers frequently stress the importance of sticking to authentic hadith and the Prophet’s Sunnah in guiding our lives:

“Whoever lies about me intentionally, let him take his seat in the Fire.” – Prophet Muhammad ﷺ (Ṣaḥīḥ al-Bukhārī). “Convey (knowledge) from me, even if it is just one verse.” – Prophet Muhammad ﷺ (Ṣaḥīḥ al-Bukhārī).

The two authentic hadiths above encapsulate both the warning that kept hadith scholars honest and the encouragement that kept them motivated. On one hand, fabricating or misquoting the Prophet is deemed a grave sin; on the other, even sharing a small bit of genuine wisdom from him is a blessed act. Inspired by such teachings, generations of scholars and students have lovingly passed the torch of hadith knowledge up until today.

Conclusion: A Living Legacy

Thanks to the monumental efforts of Imām Muslim, Imām Bukhārī, and their fellow hadith collectors, Muslims today can confidently access the Prophet’s teachings. Their books are found in mosques, libraries, and homes worldwide – often in multiple languages – guiding the faithful in matters big and small. When a Muslim wonders, “How did the Prophet deal with adversity?” or “What did he say about caring for parents?”, answers are available at their fingertips through these preserved hadiths. This is a direct result of the legacy of accuracy and devotion left by the hadith scholars.

For non-Muslims, the hadith collections stand as a remarkable historical resource as well. They demonstrate how a community, out of reverence for their Prophet, created a rigorous system to authenticate historical memories. In an age long before the printing press, these scholars built a verified network of narration that modern scholars of history can appreciate. It’s not an exaggeration to say that the Prophet Muhammad’s life is documented in a way unlike any other figure of antiquity – much of that documentation is due to the hadith preservation project.

For Muslims, what should we do with this legacy? First, we should feel deep gratitude – to Allah for preserving our Prophet’s example, and to the scholars who served as His instruments in that preservation. Saying a prayer of mercy for Imām Muslim, Bukhari, and all those in the chain (often we say raḥimahullah, “may Allah have mercy on him”) is a way of thanking them. Second, we should engage with the hadith literature responsibly. That means reading authentic collections (or reliable compilations like Riyadh al-Salihin which draw from them) to increase our understanding. It also means being cautious with quotes: in the age of the internet, we might see sayings attributed to the Prophet – we should verify if they’re actually from him (remember the lesson of verifying news in Quran 49:6!). Happily, many resources exist today – scholars, books, and online databases – to check the status of a hadith. Following the scholars’ example, we too should prefer a ṣaḥīḥ hadith over a ḍa‘īf one when seeking guidance.

Lastly, and most importantly, we should live by the teachings that these hadith convey. The point of preserving the Prophet’s words is to implement them, not just admire them historically. Imām Bukhārī is reported to have said that the true way to honor the hadith is to act upon them. The scholars of hadith were known to practice what they preached: their honesty, patience, and worship set examples for us. In the same way, learning a authentic hadith should reflect in our behavior. If we read that the Prophet ﷺ said, “Spread peace, feed the hungry, uphold family ties, and pray at night – you will enter Paradise in peace,” then we should try to spread peace and feed the needy in our own lives.

In conclusion, the legacy of Imām Muslim and the other great hadith collectors is alive among us. It lives in the prayers we pray (performed as the Prophet taught), the greetings we say (“As-salāmu ‘alaykum” as he said), the morals we uphold, and the knowledge we continue to transmit. Their work was a trust they fulfilled and passed on – now it’s on us to continue cherishing that trust. By studying the hadith with reverence and wisdom, Muslims strengthen their connection to Prophet Muhammad ﷺ. And by understanding the hadith preservation story, non-Muslims can appreciate the profound care taken to secure the Prophet’s legacy. May we all be inspired by these guardians of hadith and carry forward their mission of truth, knowledge, and faith.
