Musnad Ahmad 3065

Abu Salamah bin ‘Abdur Rahman narrated: Ibn 'Abbas used to narrate that Abu Bakr as-Siddeeq entered the mosque when 'Umar was speaking to the people, and he proceeded until he came to the house in which the Messenger of Allah (ﷺ) had died, which was 'A'ishah's house. He lifted from his face the striped cloak with which he was covered, and he looked at the face of the Prophet (ﷺ), then he leaned over him and kissed him, then he said: By Allah. Allah will not cause you to die twice. You have died a death after which you will not die again.
