The Witr Prayer with One Rak'ah and the Recitation in It

Question:
Honorable Shaykh, a questioner says: I pray 'Isha', and after that I pray al-Shaf' and al-Witr. I pray al-Witr in one rak'ah, in which I recite al-Fatihah and the Mu'awwidhat, and I prostrate. After the tashahhud, I say the taslim. Is my prayer and my Witr valid?

Answer:
Yes, you pray whatever is easy for you of the night, two by two, two rak'ahs, two rak'ahs, then you pray Witr with one, and you recite in it. You recite in it Surat al-Ikhlas. And if you recite with it, if you recite with it the two Mu'awwidhat, there is no harm in that; rather, this is an increase in good. As for al-Shaf' before it, if you pray al-Shaf' with two rak'ahs and then you pray Witr with one, you recite in the first rak'ah and you recite in the second rak'ah "Say, O you disbelievers." This is the established Sunnah.
