It was said to the Prophet ﷺ during the illness from which he died, "What is suspected to be the cause of your illness, Messenger of Allah? For my part, I do not suspect anything to be the cause of my son's illness except the poisoned sheep he ate with you at Khaybar."The Prophet ﷺ said, "And I do not suspect anything to be the cause of my own illness except that. This is the time when it has severed my aorta."
حدثنا مخلد بن خالد حدثنا عبد الرزاق حدثنا معمر عن الزهري عن ابن كعب بن مالك عن أبيه أن
للنبي ﷺ في مرضه الذي مات فيه ما يتهم بك يا رسول الله فإني لا أتهم بابني شيئا إلا الشاة المسمومة التي أكل معك بخيبر وقال النبي ﷺ وأنا لا أتهم بنفسي إلا ذلك فهذا أوان قطعت أبهري
