What should the imam do if he stood for the third rak'ah in Tarawih prayer and finished the prayer, then remembered that he had prayed three rak'ahs: should he perform the prostration of forgetfulness (sujud al-sahw) or complete it to four?
He performs the prostration of forgetfulness (sujud al-sahw), then completes the prayer two by two (rak'ahs), just as if this were in an obligatory prayer.
