Does the imam’s race invalidate the prayer?

Question : It has become clear that racing is forbidden, but if one does it and bows before his imam, or prostrates before his imam, is his prayer valid, or do we say it is invalid? And do not seek heritage.

Answer : The correct view is that his prayer is invalid as soon as he races, because this is a forbidden act, and any act of worship in which a person does something forbidden becomes invalid. So if he does this thing, while knowing that he is required to follow the imam, his prayer is invalid.
