274. Dua After Witr Prayer (Subhanal Malikil Quddus)
The Prophet (ﷺ) used to recite this dhikr three times at the end of the Witr prayer, and the last time he would say it at length:
سُبْحَانَ الْمَلِكِ الْقُّدُّوْسِ
سُبْحَانَ الْمَلِكِ الْقُّدُّوْسِ
Subhaanal-Malikil-Quddoos
Translation
Glory is to the King, the Holy.
