What was the Prophet Muhammad's (peace be upon him) opinion on praying two rak'at before the Fajr prayer?
 Narrated Anas bin Seereen:                     I asked Ibn `Umar, "What is your opinion about the two rak`at before the Fajr (compulsory) prayer, as to prolonging the recitation in them?" He said, "The Prophet (p.b.u.h) used to pray at night two rak`at followed by two and so on, and end the prayer by one rak`a witr. He used to offer two rak`at before the Fajr prayer immediately after the Adhan." (Hammad, the sub-narrator said, "That meant (that he prayed) quickly.)"
