The report in Sahih al-Bukhari shows that Muslims heard Jewish explanations of scripture, but it does not show that the Prophet (PBUH) learned the Quran from them. At most, it proves contact; it does not prove dependence.
Why the argument can sound persuasive
The strongest form of the objection is this: the Quran contains many figures known from the Bible - Adam, Noah, Abraham, Moses, Mary, Jesus and others. Seventh-century Arabia was not sealed off from Jews and Christians. Sahih al-Bukhari records that some People of the Book read the Torah in Hebrew and explained it in Arabic. So, the critic says, we have a normal human route by which biblical material could reach the Prophet Muhammad (PBUH), and since the Quran comes later than the Bible, similarity should be treated as borrowing unless proven otherwise.
"The People of the Book used to recite the Torah in Hebrew and explain it in Arabic to the Muslims. Allah's Messenger said: 'Do not believe the People of the Book and do not disbelieve them, but say: We believe in Allah and what has been revealed to us...'"
Sahih al-Bukhari 7362
That is a fair historical question. Islam does not deny that Jews and Christians existed, spoke, argued, preached and transmitted stories. The Quran itself mentions that accusation.
"And We certainly know that they say, 'It is only a human being who teaches him.' The tongue of the one they refer to is foreign, while this is a clear Arabic tongue."
Quran 16:103
What the Bukhari report actually proves
The hadith proves that some Muslims heard explanations from the People of the Book. It does not say the Prophet (PBUH) studied with them, relied on them, or used them as a source for revelation. In fact, the instruction is cautious: do not simply affirm their reports and do not simply reject them when the Quran and Sunnah have not judged the matter.
That caution makes little sense if the Quran were built upon their teaching. The Prophet (PBUH) was not saying, "Take your religion from them." He was teaching Muslims to recognize that earlier communities possessed remnants of revelation mixed with interpretation, translation, loss, and disagreement.
There is also a chronological problem for the objection. Many Quranic prophet narratives were recited in Makkah before the Prophet's (PBUH) later public dealings with Jewish tribes in Madinah. The Quran did not appear at the end of a long classroom process. It came publicly, in portions, often in response to events, while opponents were actively looking for a human teacher to expose.
Similarity is not the same as borrowing
The Quran's own explanation is not that it discovered Bible stories late, but that God revealed the same broad prophetic history again, correcting what needed correction and confirming what remained true.
"He has sent down upon you the Book in truth, confirming what was before it. And He sent down the Torah and the Gospel before, as guidance for the people."
Quran 3:3-4
So shared names and themes are expected. If Moses and Jesus were real prophets, a later revelation would not avoid them merely to look original. The real question is whether the Quran behaves like a copier. It does not. It is often brief where the Bible is detailed, detailed where the Bible is silent, and sharply different in theology: no inherited sin, no divine sonship, no crucifixion as atoning sacrifice, no depiction of prophets as morally degraded in the way some biblical passages do.
The Quran also speaks with authority over the earlier communities, not as a student anxiously preserving their versions. It challenges rabbis, priests, pagans, hypocrites and believers alike. Its prophet stories are not told as antiquarian history, but as moral revelation centered on worship, judgment, patience, repentance and the oneness of God.
What the argument does and does not establish
Historically, the argument establishes the possibility of human contact. Muslims do not need to deny that. It may also explain why some Arabs recognized names or fragments of stories.
But it does not establish that the Prophet (PBUH) authored the Quran from those contacts. For that, one would need evidence of sustained instruction, a teacher whose material matches the Quran, a plausible account of the Quran's Arabic force and structure, and an explanation of why its message so often corrects and confronts the very communities it allegedly copied.
"You did not recite any scripture before it, nor did you write it with your right hand. Otherwise the falsifiers would have had cause for doubt."
Quran 29:48
The cleaner reading is this: Arabia had traces of earlier revelation, and the Quran came claiming to restore the truth behind those traces. Contact is a fact. Dependence is an inference. Revelation remains the explanation that best fits the Quran's own voice, confidence and correction of what came before.
