Yaqoub narrated to us, my father narrated to us, from Salih ibn Kaysan, he said: Ibn Shihab said, Anas ibn Malik informed me that Abu Bakr used to lead them in prayer during the illness of the Messenger of Allah, peace and blessings be upon him, in which he passed away, until when it was Monday and they were lined up for prayer, he said: The Messenger of Allah, peace and blessings be upon him, uncovered the curtain of the chamber, and he mentioned its meaning.
