It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) used to pray two rak'ahs at a time during the night, and in the last part of the night he would perform one rak'ah of Witr. Then he would stand (to perform the two Sunnah rak'ahs of Fajr), and (he would perform them so quickly) as if the call to prayer (adhan) or the iqamah was being recited in his ear.
