Hazrat Jabir narrates that the Messenger of Allah, peace and blessings be upon him, fell from his horse and landed on the trunk of a date-palm, and his blessed foot became swollen. The narrator says: We went to visit the Prophet, peace and blessings be upon him, to inquire about his health, and found him sitting and praying in the upper room of Hazrat Aisha, may Allah be pleased with her. We prayed behind him while standing. Then, on another occasion, we visited him again and found him praying while sitting. We began to pray behind him while standing, but he gestured to us to sit down. When he finished the prayer, he said: The Imam is appointed to be followed. So, when he prays standing, pray standing like him, and when he prays sitting, pray sitting like him. Do not stand when the Imam is sitting, as the people of Persia do with their elders.
