Sahih Muslim 948
صحيح مسلم#948SahihAbu Musa reported:When the Messenger of Allah (ﷺ) became ill and illness became serious he ordered Abu Bakr to lead the people in prayer. Upon this 'A'isha said: Messenger of Allah, Abd Bakr is a man of tenderly feelings: when he would stand in your place (he would be so much overwhelmed -by grief that) he would not be able to lead the people in prayer. He (the Holy Prophet) said: You order Abu Bakr to lead the people in prayer, and added: You are like the female companions of Yusuf. So Abu Bakr led the prayer (during this period of illness) in the life of the Messenger of Allah (ﷺ)
