The Book of Prayer

And in the narration of Ibn Hibban:

"The Prophet (ﷺ) prayed two Rak'at before the Maghrib (prayer)."

Muslim has reported from Anas (RA) that he said, "We used to pray two Rak'at after sunset and the Prophet (ﷺ) used to see us, but he neither commanded nor forbade us."

Narrated 'Aishah (RA):

The Prophet (ﷺ) used to make the two (voluntary) Rak'at before the Fajr prayer so short that I would wonder whether he recited al-Fatiha (or not). [Agreed upon].

Narrated Abu Hurairah (RA):

The Prophet (ﷺ) recited Surat al-Kafirun, and Surat al-Ikhlas in the two (voluntary) Rak'at of the Fajr (prayer). [Reported by Muslim].

Narrated 'Aishah (RA):

The Prophet (ﷺ) 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 (ﷺ) 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 (ﷺ) 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 (ﷺ) 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 (ﷺ) 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 (ﷺ). [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 (ﷺ) 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 (ﷺ) 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 (ﷺ) ." 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 (ﷺ) 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 (ﷺ) 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 (ﷺ) 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."

Narrated ['Aishah (RA)]:

Allah's Messenger (ﷺ) used to pray thirteen Rak'at during the night, offering a Witr out of that with five and sitting only during the last of them. [Agreed upon].

Narrated ['Aishah (RA)]:

Allah's Messenger (ﷺ) offered Witr prayer (on different nights) at various hours, extending (from the 'Isha' prayer) up to the last hour of the night. [Agreed upon].
