It was narrated from Anas that the Prophet صلی اللہ علیہ وآلہ وسلم fell from a horse onto his right side, and they entered upon him to visit him. The time for prayer came, and when he has finished praying he said: “The Imam is appointed to be followed, so when he bows, then bow, and when he stands up, then stand up, and when he says: ‘Sami’ Allahu liman Hamidah (Allah hears the one who praises Him)’ then say: ‘Rabbanawa lakal-hamd (Our Lord, and to You be the praise).”(Sahih)
