Buraida said he heard God’s Messenger say, “The witr is a duty, so he who does not observe it does not belong to us; the witr is a duty, so he who does not observe it does not belong to us; the witr is a duty, so he who does not observe it does not belong to us.”
Ibn ‘Abbas, on being asked whether he approved of the Commander of the Faithful, Mu'awiya, using only one rak'a in the witr, replied, “He is right; he is versed in the law.” In a version Ibn Abu Mulaika said that Mu'awiya observed a witr after the evening prayer with one rak'u when a client of Ibn ‘Abbas was with him. He went to Ibn ‘Abbas and told him, but he replied, “Leave him alone, for he was a companion of the Prophet.”
Abu Sa'id reported God’s Messenger as saying, “If anyone over-sleeps and misses the witr, or forgets it, he should pray when he remembers and when he awakes.”
‘Ali said that the Prophet used to say at the end of his witr, “O God, I seek refuge in Thy good pleasure from Thine anger, and in Thy forgiveness from Thy punishment, and I seek refuge in Thy mercy from Thy wrath.* I cannot reckon the praise due to Thee. Thou art as Thou hast glorified Thyself.”
* Literally ‘in Thee from Thee’.
Abu Dawud, Tirmidhi, Nasa’i, and Ibn Majah transmitted it.
