Sahih Bukhari | Volume 5 | Hadith Number 721
Narrated by 'Aisha
When Allah 's Apostle was in good health, he used to say, "Never does a prophet die unless he is shown his place in Paradise (before his death), and then he is made alive or given option." When the Prophet became ill and his last moments came while his head was on my thigh, he became unconscious, and when he came to his senses, he looked towards the roof of the house and then said, "O Allah! (Please let me be) with the highest companion." Thereupon I said, "Hence he is not going to stay with us? " Then I came to know that his state was the confirmation of the narration he used to mention to us while he was in good health.
