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
