“Abu ‘Abd Allah (a.s.) has stated this Hadith. He (the Imam) has said, ‘You may stand up in the two Rak‘at of al-Dhuhr or others without saying Tashahhud (testimonies of belief) and remember it in the third Rak‘at before Ruku‘ (bowing down on one’s knees), you must sit down, then say Tashahhud (testimonies of belief), then stand up and complete your Salah (prayer). In case, if you do not remember until Ruku‘, then continue your Salah (prayer) until the end. When you complete it, then perform two Sajdah (prostration) because of mistake after Salam (the phrase of offering greeting of peace) and before speaking.’”
