Sahih Muslim Book 6, Hadith 72
The Apostle of Allah (ﷺ) used to turn to the right (at the end of the prayer).
I asked Anas how I should turn-to the right or to the left-when I say my prayers. He said: I have very often seen the Messenger of Allah (ﷺ) turning to the right.
When we prayed behind the Messenger of Allah (ﷺ) we cherished to be on his right side so that his face would turn towards us (at the end of the prayer), and he (the narrator) said: I heard him say: O my Lord! save me from Thy torment on the Day when Thoil, wouldst raise or gather Thy servants.
