Did the Prophet (peace be upon him) die from the poison of the sheep he ate six years before his death?

The Jews attempted to kill the Prophet, peace and blessings be upon him, on several occasions, including:

1. Their attempt to kill him in his infancy when he was with his wet nurse, Halimah al-Sa'diyah. Some of them said to each other, "Kill him," before Halimah informed them that he was not an orphan. 2. After the Battle of Badr, Banu al-Nadir attempted to assassinate him by inviting him to a meeting and then planning to kill him treacherously. However, revelation informed him of their intentions, so he besieged them and expelled them. 3. Another reason for the expulsion of Banu al-Nadir was when the Prophet, peace and blessings be upon him, went to them to seek assistance with the blood money for two slain individuals. They attempted to drop a stone on him from atop a wall, but revelation informed him, and he departed from them. 4. The incident of the poisoned sheep after the conquest of Khaybar, where a Jewish woman offered him a poisoned sheep. The traces of the poison remained in his throat, and this caused his illness from which he died as a martyr years later. He said, "O Aisha, I still feel the pain of the food I ate in Khaybar, and this is the time I feel my aorta being severed by that poison."
