Abd Khair says: We were in the mosque when Sayyiduna Ali ibn Abi Talib (may Allah be pleased with him) came to us and asked, "Where is the one who was asking about Witr?" Among us was one who had already prayed one rak‘ah (of Witr), but one rak‘ah remained for him, so he completed that rak‘ah. Then all of us gathered around him. He (Ali) said: "At first, the Messenger of Allah (peace and blessings be upon him) used to pray Witr at the beginning of the night, then he started praying it in the middle of the night, but later he maintained the performance of Witr at the time close to the break of dawn."
