Narrated 'Aishah (RA): The Prophet ( صلی اللہ علیہ وسلم ) used to lie down on his right side, after praying the two (voluntary) Rak'at of the Fajr (prayer). [Reported by al-Bukhari] .

Narrated Abu Hurairah (RA): Allah's Messenger ( صلی اللہ علیہ وسلم ) said: "If any of you prays the two Rak'at before the dawn prayer, he should lie on his right side." [Reported by Ahmad, Abu Dawud and at-Tirmidhi, the latter graded it Sahih (authentic)] .

Narrated Ibn 'Umar (RA): Allah's Messenger ( صلی اللہ علیہ وسلم ) said: "The (voluntary) night prayers are two Rak'at, two Rak'at (in pairs), and if one fears that the dawn prayer is due, he should then offer one Rak'at which will make what he has prayed an odd number." [Agreed upon). The Khamsah reported it - graded Sahib (authentic) by Ibn Hibban - with the wording: "the (voluntary) day and night prayers are two Rak'at, two Rak'at (in pairs)." an-Nasa'i said, "This is a mistake."

Narrated Abu Hurairah (RA): Allah's Messenger ( صلی اللہ علیہ وسلم ) said: "The most excellent prayer after that which is obligatory is the (voluntary) late night prayer." [Reported by Muslim] .

Narrated Abu Ayub al-Ansari (RA): Allah's Messenger ( صلی اللہ علیہ وسلم ) said: "al-Witr prayer is a duty upon every Muslim, so whoever likes to offer it with five Rak'at let him do so and whoever likes to offer it with three let him do so, and whoever likes to offer it with one let him do so." [Reported by al-Arba'ah except at-Tirmidhi. And Ibn Hibban graded it Sahib (authentic) and an-Nasa'i held that the stronger view is that it is Mawquf (saying of a companion)] .

Narrated 'Ali bin Abu Talib (RA): The Witr prayer is not obligatory as the prescribed prayer is [i.e. the five daily prayers] , but it is a Sunnah which was established by the practice of Allah's Messenger ( صلی اللہ علیہ وسلم ). [at-Tirmidhi and an-Nasa'i reported it, who graded it Hasan (good). al-Hakim graded it Sahih (authentic)] .

Narrated Jabir (RA): Allah's Messenger ( صلی اللہ علیہ وسلم ) prayed during the month of Ramadan. Then they (the Sahabah) waited for him on the following night, but he did not come out and he said, "I feared that the Witr (prayer) might be prescribed for you." [Reported by Ibn Hibban] .

Narrated Kharijah bin Hudhaifah (RA): Allah's Messenger ( صلی اللہ علیہ وسلم ) said: "Allah the Exalted has given you an extra prayer which is better for you than the red camels (high breed camels)." We asked, "What is it O Allah's Messenger." He said, "The Witr between the 'Isha' prayer and up till the break of dawn." [Reported by al-Khamsah except an-Nasa'i and al-Hakim graded it Sahih (authentic)] . Ahmad reported something similar to the above Hadith from 'Amr bin Shu'aib on the authority of his father who reported it on the authority of 'Amr's grandfather.

Narrated 'Abdullah bin Buraidah (RA) from his father: Allah's Messenger ( صلی اللہ علیہ وسلم ) said: "The Witr is a duty, so he who does not offer it, is not one of us." [Reported by Abu Dawud with a Laiyin (weak) chain of narrators and Al-Hakim graded it Sahih (authentic)] . The above mentioned Hadith has a Shahid (supporting narration) which is weak, reported by Ahmad from Abu Hurairah (RA).

Narrated 'Aishah (RA): Allah's Messenger ( صلی اللہ علیہ وسلم ) did not offer more than eleven (voluntary) Rak'at during Ramadan nor during other than Ramadan. He offered four Rak'at - Do not ask about their beauty and length! (It is beyond description or imitation] . Again he would pray four Rak'at - Do not ask about their beauty and length! [It is beyond description or imitation] . Then he would pray three (Rak'at of Witr). 'Aishah (RA) said: "I said, O Allah's Messenger will you sleep before you pray Witr?" He said, "O 'Aishah my eyes sleep, but my heart does not sleep." [Agreed upon] . And in another narration of al-Bukhari and Muslim, ['Aishah (RA)] narrated: "He used to pray ten Rak'at (of prayer), and making it Witr by one Rak'at, and he used to pray the two (Sunnah) Rak'at of Fajr, so that it became thirteen Rak'at."
