It was narrated that Aisha (RA) said: "The Messenger of Allah ﷺ SAW told Abu Bakr (RA) to lead the people in prayer when he was sick, and Abu Bakr (RA) used to lead them in prayer. Then the Messenger of Allah ﷺ SAW began to feel a little better, so he came out, and saw Abu Bakr (RA) leading the people in prayer. When Abu Bakr (RA) saw him, he stepped back, but the Messenger of Allah ﷺ SAW gestured to him to stay where he was. Then the Messenger of Allah ﷺ SAW sat beside Abu Bakr. Abu Bakr (RA) was following the prayer of the Messenger of Allah ﷺ SAW, and the people were following the prayer of Abu Bakr." (Sahih).
