“Wudu’ of a man may become invalid after he raises his head from the last Sajdah (prostration) before Tashahhud (testimonies of belief). Abu Ja’far (a.s.), has said, ’He moves to take Wudu’ and if he wants to return to Masjid or if he wants in his house, sits down to say Tashahhud (testimonies of belief) and the phrase of offering greeting of peace. If his Wudu’ becomes invalid after Tashahhud (testimonies of belief), his Salah (prayer) is passed.’”
