English translation
1702. It was narrated that Ubayy bin Ka'b said: "The Messenger of Allāh ﷺ used to recite: "Glorify the Name of your Lord, the Most High;"[1] in Witr; in the second Rak'ah he would recite: "Say: O you disbelievers!"[2] and in the third "Say: He is Allāh, (the) One."[3] And he only said the Taslīm at the end, and he would say - meaning after the Taslīm: 'Subhânal-Malikil-Quddûs (Glory be to the Sovereign, the Most Holy)' three times." (Ḍa'if)
