Abu Huraira reported:
The Messenger of Allah ( صلی اللہ علیہ وسلم ) while teaching us (the principles of faith), said: Do not try to go ahead of the Imam, recite takbir when he recites it. and when he says: Nor of those who err, you should say Amin, bow down when lie bows down, and when he says: Allah listens to him who praises Him, say: O Allah, our Lord, to Thee be the praise .
