I asked ‘A’isha whether she had seen God’s Messenger bathing because of sexual defilement in the early or the latter part of the night, and she replied, ‘‘He often bathed in the early part of the night and often in the latter part.” Thereupon I said, "God is most great. Praise be to God who has given latitude in the matter! ” I then asked whether he observed a witr in the early or the latter part of the night, and she replied, "He often observed it in the early part and often in the latter part of the night.” Thereupon I said, “God is most great. Praise be to God who has given latitude in the matter! ” I then asked whether he recited the Qur’an in a loud or in a low voice, and she replied, “He often recited it in a loud voice and often in a low voice.” Thereupon I said, “God is most great. Praise be to God who has given latitude in the matter!” Abu Dawud transmitted it, and Ibn Majah transmitted the last section.

Allah's Messenger (SAW) 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)].

“My grandfather, the Messenger of Allah (saw), taught me some words to say in Qunut of Witr: Allahumma ‘afini fiman ‘afait, wa tawallani fiman tawallait, wahdini fiman hadait, wa qini sharra ma qadait, wa barik li fima a’tait. Innaka taqdi wa la yuqda ‘alaik, innahu la yudhillu man walait. Subhanaka rabbana tabarakta wa ta’alait (O Allah, pardon me along with those whom You have pardoned, be an ally to me along with those whom You are an ally to, guide me along with those whom You have guided, protect me from the evil that You have decreed, and bless for me that which You have bestowed. For verily You decree and none can decree over You. He whom You support can never be humiliated. Glory is to You, our Lord, You are Blessed and Exalted).”

Yahya related to me from Malik from Abd ar-Rahman ibn al-Qasim that his father used to go into Makka by night when he was doing umra and do tawaf of the House and say between Safa and Marwa and delay the shaving until the morning, but he would not go back to the House and do tawaf again until he had shaved his head.

Abd ar-Rahman added, "Sometimes he would enter the mosque and do the witr prayer there without actually going near the House."

Malik said, "At-tafath is shaving the head, putting on normal clothes and things of that nature."

Yahya said that Malik was asked whether a man who forgot to shave (his head) at Mina during the hajj could shave in Makka, and he said, "That is permissible, but I prefer the shaving to be done at Mina."

Malik said, "What we are all agreed upon here (in Madina) is that no-one should shave his head or cut his hair until he has killed his sacrificial animal, if he has one, and things that are haram for him do not become halal for him until he leaves ihram at Mina on the day of sacrifice. This is because Allah, the Blessed and Exalted, says, 'Do not shave yourheads until the sacrificial animal has reached its destination. ' "

The Messenger of Allah (ﷺ) used to pray Witr reciting nine surahs from Al-Mufassal. Aswad said: In the first rak’ah he would recite `The mutual rivalry (for piling up of worldly things) diverts you` [At-Takathur 102] and “verily, We have sent it (this Qur`an) down in the Night of Al-Qadr (Decree)` [al-Qadr 97], and `When the earth is shaken with its (final) earthquake` [az-Zalzalah 99]. In the second rak`ah he would recite `By Al-‘Asr (the time)” [Al-ʻAsr 103] and `When there comes the Help of Allah (to you, O Muhammad against your enemies) and the Conquest (of Makkah)` [An-Nasr 95] and “Verily. We have granted you (O Muhammad (ﷺ)) Al-Kawthar (a river in Paradise)` [Al-Kawthar 108]. In the third rak`ah he would recite “Say (O Muhammad to these Mushrikoon and Kafiroon): `O Al-Kafiroon (disbelievers in Allah, in His Oneness, in His Angels, in His Books, in His Messengers, in the Day of Resurrection, and in Al Qadar)!” [Al-Kafiroon 109] and “Perish the two hands of Abu Lahab (an uncle of the Prophet (ﷺ)) and perish he!` [Al-Masad 109] and `Say (O Muhammad (ﷺ)): “He is Allah, (the) One“ [Al-Ikhlas 112].

“I lay down across the pillow and the Messenger of Allah (saw) and his wife were laying along it. The Prophet (saw) slept until midnight, or a little before, or a little after. The Prophet (saw) woke up and began to rub the sleep from his face with his hand. Then he recited the last ten Verses of Surah Al ‘Imran. Then he got up and went to a water skin that was hanging up and performed ablution from it, and he performed ablution well, then he stood up and prayed.” ‘Abdullah bin ‘Abbas said: “I stood up and did what he had done, then I went and stood beside him. The Messenger of Allah (saw) put his right hand on my head, took hold of my right ear and tweaked it. Then he prayed two Rak’ah, then two Rak’ah, then two Rak’ah, then two Rak’ah, then two Rak’ah, then two Rak’ah, then he prayed Witr. Then he lay down until the Mu’adh-dhin came to him and he prayed two brief Rak’ah, then he went out to pray.”

“I asked 'A'sha (may Allah be well pleased with her) about the nighttime ritual prayer of Allah’s Messenger (Allah bless him and give him peace), so she said: ‘He used to sleep at the beginning of the night. Then he would get up, and when it was the time before daybreak, he performed a witr [a ritual prayer with an odd number of cycles]. Then he came to his mattress, and if he had a need, he had sexual intercourse with his wife. When he heard the call to prayer, he sprang up, and if he was in a state of major ritual impurity, he poured water over himself, and if not, he performed the minor ritual ablution and went out to the ritual prayer.”

The Messenger of Allah ﷺ would pray two rakʿahs after witr while sitting, reciting in the two rakʿahs “Idhā zulzilat al-ardhu…” (Sūrah al-Zalzalah) and “Qul Ya Ayyuhal-Kafirun” (Sūrat al-Kāfirūn). Reference: Zad al-Ma`ad 1/322

Is Sūrat al-Zalzalah equivalent to one-fourth of the Qur’an?
The reports about Sūrat Al-Zalzalah being equivalent to one-fourth of the Qur’an have some weakness in them, although they are strengthened by the different variations as well as the multiple mursal reports (which are weak standalone). Ibn Khuzaymah categorized one particular attributed to Anas (RA) as saḥiḥ and al-Tirmidhī classified one narration as ḥasan, while others relied on the report of Ibn Abbās.

the Prophet (saas) used to say in his supplication: "Rabbi! A'inni wa la tu'in 'alayya, wansurni wa la tansur 'alayya, wamkurli wa la tamkur 'alayya, wahdini wa yassiril-huda li, wansurni 'ala man bagha 'alayya. Rabbij'alni laka shakkaran laka dhakkaran, laka rahhaban, laka muti'an, 'ilayka mukhbitan, 'ilayka awwahan muniba. Rabbi! Taqabbal tawbati, waghsil hawbati wa ajib da'wati, wahdi qalbi, wa saddid lisani, wa thabbit hujjati, waslul sakhimata qalbi (O Lord! Help me and do not help others against me, support me and do not support others against me, plan for me and do not plan against me, guide me and make guidance easy for me, and help me against those who wrong me. O Lord! Make me grateful to You, make me remember You much, make me fearful of You, obedient to You, humble before You and turning to You. O Lord! Accept my repentance and wash away my sins, answer my supplication, guide my heart, make my tongue speak the truth, make my proof firm and remove resentment from my heard)." (Sahih)(One of the narrators) Abul-Hasan At-Tanafisi said: "I said to Waki': 'Shall I say it in the Qunut of Witr?' He said: 'Yes.'"

Allah's Messenger (SAW) taught me some words to say when standing in supplication during the Witr, they were: "O Allah, guide me among those You have guided, grant me well-being among those You have granted well-being, take me into Your charge among those You have taken into Your charge, bless me in what You have given, guard me from the evil of what You have decreed, for You decree and none can decree over You. He whom You befriend is not humbled. Blessed and Exalted are You, our Rabb (Lord)."
Reported by Al-Khamsah: Authentic. Narrated by Abu Dawood (1425), an-Nasa'i (3/248), at-Tirmidhi (464), Ibn Majah (1178), and Ahmad (1/199-200).

at-Tabarani and al-Baihaqi added: "He whom You hold as enemy is not honoured." It is an authentic addition. Narrated by at-Tabarani in "Al-Kabeer" (3/73/2701) and al-Baihaqi in "Al-Kubra" (2/209).

an-Nasa'i reported through another chain of narrators, adding at its end: "May Allah the Most High send His Salat on the Prophet (praising him in the highest assemblies of the angels)." It is Weak. Narrated by an-Nasa'i (3/248), with the addition of "Muhammad" and its chain is disconnected, as stated by Al-Hafiz Ibn Hajar al-Asqalani in "At-Talkhees".
