Question # 120670: What should the person praying behind an imam do if he recites a verse in which there is a sajdah (prostration)?
Question: What should I do if I recite a soorah in which there is a sajdah when I am praying behind an imam?. Answer: Praise be to Allaah. You should not prostrate, because following the imam is obligatory and the prostration of recitation is Sunnah. If a person is praying behind an imam, it is not permissible for him to prostrate, and if he prostrates deliberately although he knows that that is not permissible, then his prayer becomes invalid.
