"The Messenger of Allah (ﷺ) led us in one of the prayers in which the recitation is done out loud, and he said: 'None of you should recite when I recite out loud, apart from the Umm Al_quran (Al Fatihah).'"
Sunan an-Nasa'i Book 11, Hadith 45
← Previous Hadith "The Messenger of Allah (ﷺ) finished a prayer in which he recited out loud, then he said: 'Did any one of you recite with me just now?' A man said: 'Yes, O Messenger of Allah.' He said: 'I was wondering what was distracting me in reciting Quran.'" So the people stopped reciting in prayers in which the Messenger of Allah (ﷺ) recited out loud when they heard that.

Sunan an-Nasa'i Book 11, Hadith 44 Next Hadith → "The Messenger of Allah (ﷺ) said: 'The Imam is appointed to be followed, so when he says the takbir, say the takbir, and when he recites, be silent, and when he says: "Sami' Allahu liman hamidah (Allah hears those who praise Him)," say: "Allahumma rabbana lakal-hamd (Our Lord, to You be praise)."
