Musnad Abi Ya'la 3567 — when the Messenger of Allah ﷺ fell ill

It is narrated from Sayyiduna Anas (may Allah be pleased with him) that "when the Messenger of Allah (peace and blessings be upon him) fell ill with the illness in which he (peace and blessings be upon him) passed away, Sayyiduna Bilal (may Allah be pleased with him) came to him (peace and blessings be upon him) and informed him of the prayer, whereupon he (peace and blessings be upon him) said: 'O Bilal, you have conveyed the message; now whoever wishes may pray, and whoever wishes may leave it.' Sayyiduna Bilal (may Allah be pleased with him) said: 'O Messenger of Allah, then who will lead the people in prayer?' He (peace and blessings be upon him) said: 'Tell Abu Bakr (may Allah be pleased with him) to lead the people in prayer.' So when Sayyiduna Abu Bakr (may Allah be pleased with him) stepped forward to lead the prayer, the curtains were raised from the blessed room of the Messenger of Allah (peace and blessings be upon him). We looked at him (peace and blessings be upon him), and his (peace and blessings be upon him) blessed face was (in its radiance and purity) as though it were a white sheet of paper, and over him (peace and blessings be upon him) was a black striped cloak (khamisah). Sayyiduna Abu Bakr (may Allah be pleased with him) thought that perhaps he (peace and blessings be upon him) wished to come out, so he began to step back, but the Messenger of Allah (peace and blessings be upon him) signalled to him: 'Stay in your place.' So Sayyiduna Abu Bakr (may Allah be pleased with him) led the prayer, and after that day we did not see the Messenger of Allah (peace and blessings be upon him) until he (peace and blessings be upon him) passed away that very day."
