It was narrated that Ubayy bin Ka'b said:
 The Messenger of Allah (ﷺ) used to recite:  Glorify the Name of Your Lord, the Most High;  in witr, in the second rak'ah he would recite:  Say: O you disbelievers! ; and in the third  Say: He is Allah, (the) One . And he only said the taslim at the end, and he would say- meaning after the taslim: Subhanal-Malikil-Quddus (Glory be to the Sovereign, the Most Holy)' three times.
