“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.’”
Sunan Ibn Majah Book 5, Hadith 45
← Previous Hadith “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, 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.’”

Sunan Ibn Majah Book 5, Hadith 44 Next Hadith → “I heard Abu Hurairah say: ‘The Prophet (ﷺ) led his Companions in a prayer; we think it was the Subh. He said: “Did anyone among you recite?” A man said: “I did.” He said: “I was saying to myself, what is wrong with me that someone is fighting to wrest the Qur’an from me?”
