It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that once a man asked the Prophet (peace and blessings be upon him) about the night prayer. At that time, I was between the Prophet (peace and blessings be upon him) and the questioner. The Prophet (peace and blessings be upon him) said: "You should pray two rak'ahs at a time, and when you fear that morning is near, then add one rak'ah as witr to those two." A year later, that man again came to the Prophet (peace and blessings be upon him); this time too, I was between the Prophet (peace and blessings be upon him) and him. He asked the same question, and the Prophet (peace and blessings be upon him) gave him the same answer.
