Ubayy b. Ka'b said that when God’s Messenger gave the salutation in the witr he said, “Glory be to the King most holy.” Abu Dawud and Nasa’i transmitted it, Nasa’i adding that he said it three times, prolonging the words. In a version by Nasa’i from ‘Abd ar-Rahman b. Abza from his father, he said that he used to say three times when he uttered that salutation, “Glory be to the King most holy”, raising his voice when saying it the third time.

‘Ali said that the Prophet (ﷺ) 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.

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.” Bukhari transmitted it.

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.” Abu Dawud transmitted it.

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.” Tirmidhi, Abu Dawud and Ibn Majah transmitted it.

Malik said he heard that a man asked Ibn ‘Umar whether the witr was obligatory, and ‘Abdallah said, “God’s Messenger observed the witr and the Muslims observed the witr.” The man kept repeating his question and ‘Abdallah kept saying, “God’s Messenger observed the witr and the Muslims observed the witr.” He transmitted it in al-Muwatta.

Nafi' said, “I was with Ibn ‘Umar in Mecca when the sky was cloudy and he was afraid the morning might have come, so he observed a witr with one rak'a. The sky then cleared and he saw that it was still night, so he made it a pair by praying one rak'a; then he prayed series of two rak'as, and when he was afraid morning was near he observed a witr with one.” Malik transmitted it.

‘A’isha said that God’s Messenger used to pray sitting, and would recite the Qur’an while sitting; then when about thirty or forty verses of his recitation remained he stood up and recited while standing. Then he bowed, then he prostrated himself, and after that he did the same kind of thing in the second rak'a. Muslim transmitted it.

Umm Salama said the Prophet (ﷺ) used to pray two rak'as after the witr. Tirmidhi transmitted it, and Ibn Majah added that they were short ones which he prayed while sitting.

‘A’isha said that God’s Messenger used to observe a witr with one rak'a, then he performed two rak'as reciting the Qur’an in the course of them seated. When he wished to bow, he stood up and bowed. Ibn Majah transmitted it.

Thauban reported the Prophet (ﷺ) as saying, “This wakefulness is a toil and a burden, so when one of you observes a witr he should pray two rak'as. If he gets up during the night, well and good; otherwise they will serve for him." Tirmidhi transmitted it.

Ibn ‘Abbas said that God’s Messenger stood in humble supplication daily for a month at the noon, afternoon; sunset, evening and morning prayer when he said, “God listens to him who praises Him” in the last rak'a, invoking a curse on some clans of the B. Sulaim, Ri‘l, Dhakwan and ‘Usayya, and those standing behind him said Amen. Abu Dawud transmitted it.

Anas said that the Prophet (ﷺ) stood in humble supplication for a month and then gave it up. Abu Dawud and Nasa'i transmitted it.

Abu Malik al-Ashja‘i said: I said to my father, “Father, you have prayed behind God’s Messenger, Abu Bakr, ‘Umar and ‘Uthman, and behind Ali here in al-Kufa for about five years. Did they stand in humble supplication?” He replied, “Sonny, it is an innovation.” Tirmidhi, Nasa’i and Ibn Majah transmitted it.

Al-Hasan said that ‘Umar b. al-Khattab congregated the people with Ubayy b. Ka‘b as imam and he led them in prayer for twenty nights, but led them in humble supplication only in the second half. When the last ten days came he withdrew and prayed in his house, and the people were saying, “Ubayy has run away.” Abu Dawud transmitted it.

Anas b. Malik was asked about standing in humble supplication and replied, “God’s Messenger stood in humble supplication after bowing.” A version has “before and after bowing.” Ibn Majah transmitted it.

Abu Huraira said that God’s Messenger used to commend prayer at night in Ramadan, but did not command it as a duty. He would say, “If anyone prays during the night in Ramadan because of faith and seeking his reward from God, his former sins will be forgiven him.” When God’s Messenger died this was the practice, and it continued thus during Abu Bakr’s Caliphate and the early part of ‘Umar’s. Muslim transmitted it.

Jabir reported God’s Messenger as saying, “When one of you performs the prayer in his mosque he should leave a portion of his prayer for his house, for God blesses his house because of his prayer.” Muslim transmitted it.

Zaid b. Thabit reported God s Messenger as saying, “A man’s prayer in his house is more excellent than his prayer in this mosque of mine, except for the prescribed prayer." Abu Dawud and Tirmidhi transmitted it.

‘Abd ar-Rahman b. ‘Abd al-Qari said: I went out one night to the mosque with ‘Umar b. al-Khattab and we saw the people in sections separate from one another, one man praying by himself, and another followed by a group; so ‘Umar said, “If I collected these people behind one reciter it would be better." He then made up his mind and collected them with Ubayy b. Ka‘b as imam. Afterwards I went out with him another night when the people were following the prayer of their reciter, and ‘Umar said, “This is a good innovation, but what you miss through sleeping is more excellent than what you are getting up for, meaning at the end of the night, for the people were getting up during the early part of the night. Bukhari transmitted it.
