What did the Prophet Muhammad (saw) say about the night prayer?
      Narrated Ibn Umar:                          Once a person asked Allah's Apostle about the night prayer. Allah's      Apostle replied, "The night prayer is offered as two Rakat followed by     two Rakat and so on and if anyone is afraid of the approaching dawn      (Fajr prayer) he should pray one Raka and this will be a Witr for all      the Rakat which he has prayed before."
