Witr (Odd-Numbered Prayer)
A strongly recommended prayer with an odd number of rak'ah, prayed after Isha.
Witr (Arabic: وتر) means "odd" and is a prayer performed with an odd number of rak'ah (1, 3, 5, 7 or 9), typically after the Isha prayer and before Fajr. Witr is strongly recommended (wajib according to the Hanafi school) and was a prayer that Prophet Muhammad (peace be upon him) never omitted.
The most common form is three rak'ah, either prayed as a continuous three rak'ah or as two rak'ah followed by one. In the last rak'ah of Witr, the Qunut supplication (a special du'a) is typically recited after ruku.
The Prophet said: "Allah is Witr (One) and He loves Witr. So pray Witr, O followers of the Quran." Witr is the last prayer one prays at night — if one plans to pray Tahajjud, one should postpone Witr until after Tahajjud.
