Muhammad died in Medina after a final illness. The standard Muslim account does not say he was killed in battle or executed by enemies. It presents his death as the death of a messenger whose mission had reached completion.
At the same time, Ṣaḥīḥ al-Bukhārī 4428 reports that during the illness in which he died, Muhammad said he still felt pain from the poisoned food he had eaten at Khaybar and felt as if his aorta was being cut from that poison.
What Islamic sources say
Two sources frame the question.
- Q 3:144 reminds Muslims that Muhammad is mortal: “Muhammad is not but a messenger. Other messengers have passed on before him.” The point is that Islam is not supposed to collapse when Muhammad dies.
- Ṣaḥīḥ al-Bukhārī 4428 belongs to Bukhārī’s chapter on the Prophet’s sickness and death. It preserves ʿĀʾishah’s report that Muhammad connected his final pain with the food he ate at Khaybar.
Where the question gets more complicated
Muslims can read the Khaybar report in more than one way. Some treat it as part of Muhammad’s final suffering without calling it the legal cause of death. Others note that Bukhārī’s wording is strong enough that the poison cannot simply be ignored.
The careful point is not to sensationalize the report. The careful point is that the most trusted Sunni collection preserves a connection between Muhammad’s final illness and the earlier poisoning episode.
Two ways to understand the evidence
Traditional Muslim framing
A Muslim may say: Muhammad died when Allah decreed, after completing his mission, and his suffering does not undermine his prophethood.
Source-focused framing
Others say: the sources should be allowed to speak plainly. Muhammad died after illness, and Bukhārī includes a report connecting that final illness with the poison of Khaybar.

| Source | What it covers |

| Q 3:144 | Muhammad is a messenger; previous messengers passed away. |
| Ṣaḥīḥ al-Bukhārī 4428 | Muhammad links his final pain with the poisoned food at Khaybar. |
How to think about it
- Start with mortality. The Qurʼān itself says Muhammad is a messenger who will die like earlier messengers.
- Read Bukhārī directly. The Khaybar poison report is not a modern invention; it is in a canonical Sunni source.
- Avoid overclaiming. The report matters, but the page should not pretend every Muslim scholar explains causality the same way.
Common objections
- Does this mean Muhammad failed as a prophet?
Not by itself. The question here is historical and source-based: what do Islamic sources report about his death?
- Was he poisoned?
Bukhārī reports that he connected his final pain with the Khaybar poison. Whether someone describes that as the cause of death is an interpretive conclusion.
