PROPHET’S ROUTINE AFTER SALAAH (SALAT)
It was customary with the Prophet (SallAllahu Alaihi Wa Sallam) that after salutation, he use to say: I seek the forgiveness of ALLAH) thrice and then, ‘O ALLAH, Thou art peace, and peace comes from Thee. Blessed are Thou, O possessor of Glory and Honour.’ [Muslim]
He would remain sitting facing Qiblah so long as he recited the above dua and then used to turn towards the worshippers on the right or left. lbn Masud (Radi Allahu Ta’ala Anhu) narrated that he saw the Prophet turning to left many a time while Hadrat Anas (Radi Allahu Ta’ala Anhu) narrated that he saw the Prophet turning to right very often.
