Witr

Witr (Arabic: وتر) is an Islamic prayer (salat) that is performed at night after Isha (night-time prayer) or before fajr (dawn prayer). Witr has an odd number of raka'at prayed in pairs, with the final raka'ah prayed separately. According to Abdullah ibn Umar, Muhammad: "The night prayer is offered as two raka'at followed by two raka'at and so on and if anyone is afraid of the approaching dawn (fajr prayer), he should pray one raka'ah and this will be a witr for all the raka'at which he has prayed before." In a hadith transmitted by Abu Darda, he states that Muhammad told him to do three things: to fast three days every month, to offer the witr salat before sleep, and to offer two raka'at sunnah for fajr. There is a hadith that says that the best time for the witr salat is at night, and that those who fear that they will not be able to awake, or may die in their sleep, should perform the prayer before sleeping. Ali ibn Abi Talib said, "The witr prayer is not required like your obligatory prayers but the Prophet would perform the witr prayer and say, 'O you people of the Quran, perform the witr prayer, for Allah is One and He loves the witr.'"(this is rated as daif (Weak))
