In a Sahih Hadith narrated on the authority of Aisha {May Allah be pleased with her}, that the Messenger of Allah {ﷺ} told Abu Bakr {May Allah be pleased with him} to lead the people in prayer when he was sick, and Abu Bakr used to lead them in prayer.
Then the Messenger of Allah {ﷺ} began to feel a little better, so he came out, and saw Abu Bakr leading the people in prayer.
When Abu Bakr saw him, he stepped back, but the Messenger of Allah {ﷺ} gestured to him to stay where he was.
Then the Messenger of Allah {ﷺ} sat beside Abu Bakr. Abu Bakr was following the prayer of the Messenger of Allah {ﷺ}, and the people were following the prayer of Abu Bakr.”
{Sunan of Imam ibn Majah}
