When Messenger of Allah ﷺ became seriously ill, Bilal came to him for the prayer. He said, "Tell Abu Bakr to lead the people in the prayer." I said, "O Messenger of Allah ﷺ! Abu Bakr is a softhearted man and if he stands in your place, he would not be able to make the people hear him. Will you order ʿUmar (to lead the prayer)?" The Prophet ﷺ said, "Tell Abu Bakr to lead the people in the prayer." Then I said to Hafsa, "Tell him, Abu i Bakr is a softhearted man and if he stands in his place, he would not be able to make the people hear him. Would you order ʿUmar to lead the prayer?' " Hafsa did so. The Prophet ﷺ said, "Verily you are the companions of Joseph. Tell Abu Bakr to lead the people in the prayer." So Abu- Bakr stood for the prayer. In the meantime Messenger of Allah ﷺ felt better and came out with the help of two persons and both of his legs were dragging on the ground till he entered the mosque. When Abu Bakr heard him coming, he tried to retreat but Messenger of Allah ﷺ beckoned him to carry on. The Prophet ﷺ sat on his left side. Abu Bakr was praying while standing and Messenger of Allah ﷺ was leading the prayer while sitting. Abu Bakr was following the Prophet ﷺ and the people were following Abu Bakr (in the prayer).
