It was narrated that Abu Musa Al-Ash’ari said: “The Messenger of Allah (ﷺ) said: ‘When the Imam recites, then listen attentively, and if he is sitting (in the prayer) then the first remembrance that anyone of you recites should be the Tashahhud.’”

It was narrated that Abu Hurairah said: “The Messenger of Allah (ﷺ) said: ‘The Imam has been appointed to be followed, so when he says Allahu Akbar, then say Allahu Akbar, when he recites, then listen attentively; when he says: Not (the way) of those who earned Your anger, nor of those who went astray,[1:7] then say Amin; when he bows then bow; when he says Sami’ Allahu liman hamidah (Allah hears those who praise Him), then say Allahumma Rabbana wa lakal-hamd (O Allah, our Lord, to You is the praise);” when he prostrates then prostrate; and if he prays sitting down then all of you pray sitting down.’”

It was narrated that ‘Aishah said: “The Messenger of Allah (ﷺ) fell ill and some of his Companions came to visit him. The Messenger of Allah (ﷺ) performed prayer while sitting down, and they prayed behind him standing up. He gestured them to sit down, and when he finished he said: ‘The Imam is appointed to be followed. When he bows, then bow; when he stands up again, then stand up, and if he prays sitting down then pray sitting down.’”

It was narrated from Anas bin Malik that the Prophet (ﷺ) fell from his horse and he suffered some lacerations on his right side. We went to visit him and the time for prayer came. He led us in prayer sitting down, and we prayed behind him sitting down. When he finished the prayer he said: “The Imam is appointed to be followed. When he says Allahu Akbar, then say Allahu Akbar; when he bows, then bow; when he says Sami’ Allahu liman hamidah, then say Rabbana wa lakal-hamd; when he prostrates then prostrate; and if he prays sitting down then pray sitting down.”

It was narrated that Abu Hurairah said: “The Messenger of Allah (ﷺ) said: ‘The Imam is appointed to be followed. When he says Allahu Akbar, then say Allahu Akbar; when he bows, then bow; when he says Sami’ Allahu liman hamidah, then say Rabbana wa lakal-hamd; when he prostrates then prostrate; if he prays standing, then pray standing, and if he prays sitting down then pray sitting down.”

It was narrated that Jabir said: “The Messenger of Allah (ﷺ) fell ill, and we prayed behind him while he was sitting down, and Abu Bakr was saying the Takbir so that the people could hear them. He turned to us and saw us standing, so he gestured to us to sit down. When he had said the Salam, he said: ‘You were about to do the action of the Persians and Romans, who remain standing while their kings are seated. Do not do that. Follow the lead of your Imam; if he prays standing, then pray standing, and if he prays sitting down, then pray sitting down.’”
