When Allah's Messenger (ﷺ) was healthy, he used to say, "No prophet dies till he is shown his place in Paradise, and then he is given the option (to live or die)." So when death approached him(during his illness), and while his head was on my thigh, he became unconscious for a while, and when he recovered, he fixed his eyes on the ceiling and said, "O Allah! (Let me join) the Highest Companions (see Qur'an 4:69)," I said, "So, he does not choose us." Then I realized that it was the application of the statement he used to relate to us when he was healthy. So that was his last utterance (before he died), i.e. "O Allah! (Let me join) the Highest Companions."
Sahih al-Bukhari Book 80, Hadith 45
← Previous Hadith Allah's Messenger (ﷺ) used to seek refuge with Allah from the difficult moment of a calamity and from being overtaken by destruction and from being destined to an evil end, and from the malicious joy of enemies. Sufyan said, "This narration contained three items only, but I added one. I do not know which one that was."

Sahih al-Bukhari Book 80, Hadith 44 Next Hadith → I came to Khabbab who had been branded with seven brands(1) and he said, "Had Allah's Messenger (ﷺ) not forbidden us to invoke (Allah) for death, I would have invoked (Allah) for it."
