The fear and trembling experienced by the Prophet Muhammad (PBUH) at the first revelation were natural human reactions to an overwhelming angelic encounter, not evidence of a demonic experience.

The Authentic Report Must Be Read Precisely

The most authoritative report of the first revelation is the hadith of Aisha (may Allah be pleased with her) in Sahih al-Bukhari and Sahih Muslim. It says that the Prophet Muhammad (PBUH) was met in the cave of Hira by the angel, commanded to recite, pressed in a way that overwhelmed him, and then returned to Khadijah (may Allah be pleased with her) frightened and asking to be covered. The report states that he feared for himself; it does not state that he concluded the source was demonic.

The angel came to him and said, "Recite." He said, "I am not a reciter." He said, "Then he took hold of me and pressed me until I reached the limit of endurance..." Then the Messenger of Allah (PBUH) returned with it, his heart trembling, and entered upon Khadijah bint Khuwaylid, saying, "Cover me! Cover me!" So they covered him until the fear left him.

Sahih al-Bukhari, Bad al-Wahy; Sahih Muslim, Kitab al-Iman

The wording matters. "I feared for myself" is a statement of alarm after an unprecedented event. It is not a doctrinal judgment that the visitor was a devil. A moment of fear before full reassurance is not evidence against prophethood.

Do Not Build the Objection on Unestablished Additions

Some polemical versions rely on reports outside the connected Bukhari-Muslim wording, such as sira reports that he feared being a poet or possessed, or the story that Khadijah tested the visitor by uncovering herself. Such reports are not established at the level of the Sahih hadith of Aisha, and Muslim belief does not rest on them. The firmly established point is that the Prophet (PBUH) was frightened, sought reassurance, and was then reassured by Khadijah and Waraqa.

Fear Does Not Mean the Encounter Was Evil

The Quran itself shows that righteous people and prophets could feel fear when angels appeared to them. Ibrahim (Abraham) became apprehensive when his angelic guests did not eat:

But when he saw their hands not reaching for it, he felt them unfamiliar and felt fear of them. They said, "Fear not. We have been sent to the people of Lut."

Quran 11:70

Maryam also sought refuge in Allah when the messenger sent to her appeared in human form:

Then We sent to her Our Spirit, and he appeared to her as a well-proportioned man. She said, "Indeed, I seek refuge in the Most Merciful from you, if you fear Allah." He said, "I am only the messenger of your Lord to give you a pure boy."

Quran 19:17-19

So the argument "he was afraid, therefore it was demonic" is a false standard. Fear can accompany a true angelic encounter because angels are not ordinary human visitors.

Khadijah's Reassurance Was Moral and Theological

Khadijah did not dismiss the matter carelessly. She reasoned from the Prophet's known character and from Allah's justice. A man known for truthfulness, mercy, generosity, and support of the weak was not someone Allah would abandon to disgrace.

She said, "Never! By Allah, Allah will never disgrace you. You uphold family ties, bear the burdens of the weak, support the deprived, honor the guest, and help in genuine hardship."

Sahih al-Bukhari, Bad al-Wahy; Sahih Muslim, Kitab al-Iman

She then took him to Waraqa ibn Nawfal, a learned man familiar with earlier scripture. After hearing what happened, Waraqa identified the visitor as the Namus, meaning the angelic bearer of revelation, sent to Musa (Moses):

He said, "This is the Namus whom Allah sent down upon Musa."

Sahih al-Bukhari, Bad al-Wahy; Sahih Muslim, Kitab al-Iman

Waraqa's statement is not the foundation of Muslim belief, but it is historically significant: someone familiar with earlier revelation recognized the pattern as prophetic, not demonic.

The Revelation Itself Refutes a Satanic Source

The first words revealed commanded the Prophet (PBUH) to recite in the name of Allah, the Creator and Teacher of mankind:

Recite in the name of your Lord who created, created man from a clinging substance. Recite, and your Lord is the Most Generous, who taught by the pen, taught man that which he knew not.

Quran 96:1-5

The Quran then consistently calls to worshiping Allah alone, rejecting idols, purifying the soul, honoring parents, giving charity, justice, prayer, chastity, truthfulness, and mercy. This is not the program of devils. The Quran describes the type of people upon whom devils descend:

Shall I inform you upon whom the devils descend? They descend upon every sinful liar. They pass on what is heard, and most of them are liars.

Quran 26:221-223

This description is the opposite of Muhammad (PBUH), who was known before revelation for truthfulness and trustworthiness. The Quran also explicitly denies that the revelation came from a devil:

Indeed, it is the word of a noble messenger, possessed of power and secure in position with the Owner of the Throne, obeyed there and trustworthy. And your companion is not mad... And it is not the word of an accursed devil.

Quran 81:19-25

Conclusion

The first revelation was overwhelming, and the Prophet's fear was real. But fear is not evidence of a demonic source. The authentic report, the Quranic pattern of angelic encounters, Khadijah's reasoning, Waraqa's recognition, the Prophet's character, and the message of the Quran all point in one direction: this was the beginning of true prophethood, not a demonic experience.

Related objections about the source of the Quran and the truthfulness of the Prophet (PBUH) should be assessed in light of the same evidence: the revelation's content, its preservation, and the character of the one who conveyed it.
