Tahajjud: To be Read After Witr

سُبْحَانَ الْمَلِكِ الْقُدُّوْسِ.
Translation: How Perfect is the Sovereign, the Most Holy.
Transliteration: Subḥāna-l-Maliki-l-Quddūs.
Virtue: Ubayy b. Kaʿb (raḍiy Allāhu ʿanhu) narrated that the Messenger of Allah ﷺ used to perform Witr with three rakʿahs. In the first he would recite [Sūrah al-Aʿlā]; in the second [Sūrah al-Kafirun]; and in the third [Sūrah al-Ikhlas]. And he would say the Qunūt before bowing. And when he finished he would say [the above] three times, and would elongate the words the last time (i.e. the third time). (Nasā’ī 1699)
