It was narrated from Salim, from his father, that the Prophet (S.A.W) joined them (Maghrib and 'Isha') in Al-Muzdalifah, and he prayed each of them with an Iqamah, and he did not offer any voluntary prayer before or after either of them.

The Prophet (PBUH) used to perform his voluntary prayer at night (i.e., Tahajjud prayer) while she was sleeping in front of him; and when the Witr prayer was yet to be observed, he would awaken her to perform her Witr prayer.

[Muslim].

The Prophet (PBUH) said, "O people! perform your (voluntary) Salat (prayers) in your homes because the best Salat of a man is the one he performs at home, except the obligatory Salat."

[Al-Bukhari and Muslim].

the Prophet said: "O Abu Dharr! There will be leaders after me who cause the Salat to die; so perform the Salat during its time. If you pray (with them) during its time, then that will be voluntary Salat for you, if not, then you will have attained your Salat."

The Prophet (PBUH) used to perform two Rak'ah short prayer between the Adhan (call to prayer) and the Iqamah of the dawn (Fajr) prayers.

[Al- Bukhari and Muslim]

In another narration, 'Aishah (May Allah be pleased with her) said: The Messenger of Allah (PBUH) used to perform two supererogatory Rak'ah prayer of Fajr and make them so short in duration that I used to think whether he (PBUH) had recited Surat Al-Fatihah (in it) or not.

[Al-Bukhari and Muslim]

In the narration of Muslim, 'Aishah (May Allah be pleased with her) said: When the Messenger of Allah (PBUH) used to hear the Adhan (of Fajr prayer) he would perform two supererogatory Rak'ah prayer and would make them short.

The Prophet (saws) as saying: If anyone prays in a day and a night twelve rak'ahs voluntarily (supererogatory prayer), a house will be built from him in Paradise on account of these (rak'ahs).

we used to offer supererogatory prayers and recite supplications while we were standing, and would glorify Allah while bowing and prostrating.

The aforesaid tradition has also been transmitted to the same effect by by Al Zuhri with a different chain of narrators beginning with Ibn Hanbal on the authority of Hammad. This version adds “With an iqamah for every prayer, he did not call adhan for the first prayer and he did not offer supererogatory prayer after any of them. The narrator Makhlad said “He did not call adhan for any of them.”

The Messenger of Allah (ﷺ) did not offer any prayer after which (nafl) prayer may be offered, but he prayed two rak`ahs after it.

The Prophet (PBUH) said, "Observe part of the [Nawafil (voluntary)] Salat (prayers) in your homes. Do not turn your homes into graves."

[Al-Bukhari and Muslim].

He reported God’s Messenger as saying, “Sonny, avoid turning to the side when you are engaged in prayer, for turning to the side produces destruction. If you must do it, do it in the voluntary, but not in the obligatory prayer.” Tirmidhi transmitted it.

"The Messenger of Allah (saws) asked me: 'How will you act, Abu Dharr, when you are under rulers who kill prayer or delay it (beyond its proper time) ?' I said: 'Messenger of Allah, what do you command me ?' He replied: 'Offer the prayer at its proper time, and if you say it along with them, say it, for it will be a supererogatory prayer for you.'"

"I never saw the Messenger of Allah (SAW) offer his voluntary prayers sitting down until one year before his death. Then he used to pray sitting down, reciting the surah so slowly that it seemed to be longer than a surah that is longer."

“The first thing for which a person will be brought to account on the Day of Resurrection will be his prayer. If it is complete, then the voluntary (prayers) will also be recorded for him (as an increase). If it is not complete then Allah will say to His angels: ‘Look and see whether you find any voluntary prayers for My slave, and take them to make up what is lacking from his obligatory prayers.’ Then all his deeds will be reckoned in like manner.”

"I knocked at the door when the Messenger of Allah (SAW) was offering a voluntary prayer. The door was in the direction of the Qiblah so he took a few steps to his right or left and opened the door, then he went back to where he was praying."

I prayed by the side of the Messenger of Allah (saws) in the supererogatory prayer and I heard him say: "I refuge in Allah from the Hell-Fire; woe to the inmates of the Hell-fire!"

The Prophet (saws) would recite in the two (supererogatory) rak'ahs of the dawn prayer: "Say, O unbelievers" [Surat al-Kafiroon:1] and "Say: He is Allah, the one" [Surat al-Ikhlas:1]

I accompanied Ibn 'Umar on the way (on a journey). He led us in two rak'ah's of (the noon) prayer. Then he proceeded and saw some people standing. He asked: What are they doing ? I replied: They are glorifying Allah (i.e. offering supererogatory prayer). He said: If I had offered the supererogatory prayer (while travelling), I would have completed prayer, my cousin. I accompanied the Messenger of Allah (saws) during the journey, he did not pray more than two raka'at until his death. I also accompanied Abu Bakr, and he prayed two raka'at and nothing more until he died. I also accompanied 'Umar, and he prayed two raka'at and nothing more until he died. I also accompanied 'Uthman, and he prayed two raka'at and nothing more until he died. Indeed Allah, the Exalted, said: "Certainly you have in the Messenger of Allah an excellent exemplar"

"I heard Sufyan reciting this tashahhud in the obligatory and voluntary prayers, and he said: 'Abu Ishaq narrated to us from Abu Al-Ahwas from Abdullah, from the Prophet (SAW).'" And Mansur and Hammad narrated to us from Abu Wa'il, from Abdullah, from the Prophet (SAW).

when one of you is in doubt about his prayer (i.e, how much he has prayed), he should throw away his doubt and base his prayer on what he is sure of. When he is sure about the completion of his prayer, he should make two prostrations (at the end of the prayer). If the prayer is complete, the additional rak’ah and the two prostrations will be supererogatory prayer. If the prayer is incomplete, the additional rak’ahs will compensate it, and the two prostrations will be a disgrace for the devil.

I had been asking about, as I was desirous to find one among people who should inform me, whether the Messenger of Allah (may peace be upon him) observed the forenoon prayer, but I found none to narrate that to me except Umm Hani, daughter of Abu Talib (the real sister of Hadrat 'Ali), who told me that on the day of the Conquest the Messenger of Allah (may peace be upon him) came (to our house) after the dawn had (sufficiently) arisen. A cloth was brought and privacy was provided for him (the Holy Prophet). He took a bath and then stood up and observed eight rak'ahs. I do not know whether his Qiyam (standing posture) was longer, or bending or prostration or all of them were of equal duration. She (Umm Hani) further said: I never saw him saying this Nafl prayer prior to it or subsequently. (Al-Muradi narrated on the authority of Yunus that he made no mention of the words:" He informed me." )

“Offer prayer on time, and if you reached the Imam leading them in prayers (on time), then perform it with them, and you will be safe with your prayer, otherwise it will be voluntary for you.”

"The Messenger of Allah joined Maghrib and Isha with no (Voluntary) prayer in between them. He prayed Maghrib with three Rakahs and Isha with two." And Abdullah bin Umar used to join them in like manner until he met Allahm, The Mighty and Sublime.

I head the Prophet(saws) uttering (all these supplications) in a supererogatory prayer; he narrated the tradition in a similar manner.

The Prophet (ﷺ) used to pray eight rak`ahs of voluntary prayer and during the day twelve rak`ahs.

Nafi' said that ‘Abdallah b. ‘Umar used to see his son ‘Ubaidallah saying supererogatory prayers while on a journey, and did not express disapproval. Malik transmitted it.

Yahya related to me from Malik that he had heard that Urwa ibn az-Zubayr and Said ibn al-Musayyab used to pray voluntary prayers sitting.

I entered the mosque, when the Messenger of Allah (may peace be upon him) had been sitting among people, and I also sat down among them. Upon this the Messenger of Allah (may peace be upon him) said: What prevented you from offering two rak'ahs (of Nafl prayer) before sitting down? I said: Messenger of Allah, I saw you sitting and people sitting (around you and I, therefore, sat in your company). He (the Holy Prophet) then said: When anyone among you enters the mosque, he should not sit till he has observed two rak'ahs.

When the Messenger of Allah (saws) was on a journey and wished to say voluntary prayer, he made his she-camel face the qiblah and uttered the takbir (Allah is most great), then prayed in whatever direction his mount made his face.

When we encamped, we would not offer (voluntary) prayers until we had unsaddled our beasts.

[Abu Dawud].

"The Prophet prayed Maghrib in the Masjid of Banu Abdul-Ashbal, and some people stood to offer voluntary prayers, so the Prophet said: 'This Salat is to be performed by you in your homes.'"

“There will be leaders who will be distracted by matters and they will delay the prayer until after its proper time. So make your prayer with them voluntary.”

‘A’isha said, “When God’s Messenger was praying voluntary prayers with his door bolted I came and asked to have the door opened, and he went and opened it for me, then returned to his place of prayer.” She mentioned that the door faced the qibla. Ahmad, Abu Dawud and Tirmidhi transmitted it, and Nasa’i transmitted something similar.

Al-Hasan (al-Basri) would recite fatihat al-kitab in the noon and afternoon prayers while he led in prayer or he was behind the imam and would glorify Allah, and would repeatedly say: “Allah is most great” and “ There is no god but Allah” (i.e takbir and tahlil) equal to the amount one recites al-Qaf (Surah 50) and al-Dhariyat(surah 51).

"I asked whether the Messenger of Allah prayed voluntary prayer when traveling, but I could not find anyone to tell me until Umm Hani' bint Abu Talib told me that he had come during the year of the Conquest (of Makkah). He ordered that a screen be held up, and that was done, and he took a bath; then he prayed eight Rak'ah (units) of voluntary prayer."

God’s Messenger asked me, “How will you act when you are under rulers who make prayer a dead thing, or delay it beyond its proper time?” When I asked what he commanded me to do he replied, “Observe the prayer at its proper time, and if you can say it along with them do so, for it will be a supererogatory prayer for you.” Muslim transmitted it.

We came to the house of 'Abdullah b. Mas'ud. He said: Have these people said prayer behind you? We said: No. He said: Then stand up and say prayer. He neither ordered us to say Adhan nor Iqama. We went to stand behind him. He caught hold of our hands and mode one of us stand on his right hand and the other on his left side. When we bowed, we placed our hands on our knees. He struck our hands and put his hands together, palm to palm, then put them between his thighs. When he completed the prayer he said. There would soon come your Amirs, who would defer prayers from their appointed time and would make such delay that a little time is left before sunset. So when you see them doing so, say prayer at its appointed time and then say prayer along with them as (Nafl), and when you are three, pray together (standing in one row), and when you are more than three, appoint one amongst you as your Imam. And when any one of you bows he must place his hands upon hie thighs and kneel down. and putting his palms together place (them within his thighs). I perceive as if I am seeing the gap between the fingers of the Messenger of Allah (may peace he upon him).

My friend (i.e. the Prophet) instructed me to observe three practices which I never leave: he instructed me to fast three days every month, and not to sleep but after observing the witr, and to observe supererogatory prayer in the forenoon while traveling and while resident.

I asked Anas b. Malik about the voluntary prayers after the afternoon prayer and he replied, “Umar used to forbid prayer after the afternoon prayer, but in the time of God’s Messenger we used to pray two rak'as after the setting of the sun before the sunset prayer.” I asked him whether God’s Messenger prayed these two and he replied, “He used to see us praying them, but neither commanded us nor forbade us to do so.” Muslim transmitted it.

Yahya related to me that Malik said, "I have heard from Nafi that Abdullah ibn Umar used to see his son, Ubaydullah ibn Abdullah, doing voluntary prayers on a journey,and he would not disapprove of it."

The Messenger of Allah (PBUH) said, "The first of man's deeds for which he will be called to account on the Day of Resurrection will be Salat. If it is found to be perfect, he will be safe and successful; but if it is incomplete, he will be unfortunate and a loser. If any shortcoming is found in the obligatory Salat, the Glorious and Exalted Rubb will command to see whether His slave has offered any voluntary Salat so that the obligatory Salat may be made up by it. Then the rest of his actions will be treated in the same manner."

[At- Tirmidhi].

The Messenger of Allah (PBUH) said, "When anyone of you enters the mosque, he should perform two Rak'ah (of voluntary prayer) before sitting."

[Al-Bukhari and Muslim].

He who observed twelve voluntary rak'ahs, a house will be built for him in Paradise.

Are you not surprised at AbuHurayrah? He came and sat beside my apartment, and began to narrate traditions from the Messenger of Allah (saws) making me hear them. I was saying supererogatory prayer. He got up (and went away) before I finished my prayer. Had I found him, I would have replied to him. The Messenger of Allah (saws) did not narrate traditions quickly one after another as you narrate quickly.

The Messenger of Allah (PBUH) recited in the two supererogatory Rak'ah of the Fajr prayer Surat Al-Kafirun (No. 109) [in the first Rak'ah], and Surat Al-Ikhlas (No. 112) [in the second Rak'ah].

[Muslim].

They are dearer to me than the whole world.

“The Messenger of Allah (saw) said: ‘You may come across people who offer a prayer at the wrong time. If you meet them, then perform prayer in your houses at the time that you know, then pray with them and make that voluntary.”

Yahya related to me from Malik that he had heard that Abdullah ibn Umar used to say, "(Voluntary) prayer in both the day and night is two at a time with a taslim after every 2 raka'ahs."

Malik said, "That is the custom among us."

Umm Habiba reported God’s Messenger as saying, “A house will be built in paradise for anyone who prays in a day and a night twelve rak'as, four before and two after the noon prayer, two after the sunset prayer, two after the evening prayer, and two before the dawn prayer.” Tirmidhi transmitted it. In a version by Muslim she said she heard God’s Messenger say, “If any Muslim prays to God twelve voluntary rak'as daily, over and above the obligatory ones, God will build a house for him in paradise,” or, “a house will be built for him in paradise.”

I wrote to Nafi' asking him about Nafl (spoils of war) and be wrote to me that Ibn 'Umar was among that expedition. (The rest of the hadith is the same.)
