The Prophet (ﷺ) went out at night and found AbuBakr praying in a low voice, and he passed Umar ibn al-Khattab who was raising his voice while praying.

When they both met the Prophet (ﷺ) together, the Prophet (ﷺ) said: I passed by you, AbuBakr, when you were praying in a low voice. He replied: I made Him hear with Whom I was holding intimate converse, Messenger of Allah. He (the Prophet) said to Umar: I passed by you when you were praying in a loud voice. He replied: Messenger of Allah, I was awakening the drowsy and driving away the Devil.

Al-Hasan added in his version: The Prophet (ﷺ) said: Raise your voice a little, AbuBakr, and he said to Umar: Lower your voice a little.

Raise your voice a litte ; or he said to 'Umar: Lower your voice a little. But this version adds: (The Prophet said:) I heard you, Bilal, (reciting) ; you were reciting partly from this surah and partly from that surah. He said: This is all good speech ; Allah has combined one part with the other; The Prophet (ﷺ) said: All of you were correct.

A man got up at night and recited the Qur'an in a loud voice. When the dawn came, the Messenger of Allah (ﷺ) said: May Allah have mercy on so-and-so who reminded me many verses that I had nearly forgotten.

Abu Dawud said: Harun al-Nahwi transmitted from Hammad b. Salamah the Quranic verse of Surah Al-'Imran: "How many of the prophet fought (in Allah's way)" (3:146)

The Messenger of Allah (ﷺ) retired to the mosque. He heard them (the people) reciting the Qur'an in a loud voice. He removed the curtain and said: Lo! every one of you is calling his Lord quietly. One should not trouble the other and one should not raise the voice in recitation or in prayer over the voice of the other.

The Prophet (ﷺ) said: One who recites the Qur'an in a loud voice is like one who gives alms openly; and one who recites the Qur'an quietly is one who gives alms secretly.

The Messenger of Allah (ﷺ) used to pray ten rak'ahs during the night, and would observe the witr with one rak'ah, he then prayed two rak'ahs of the dawn prayer. Thus he prayed thirteen rak'ahs in all.

The Messenger of Allah (ﷺ) used to pray eleven rak'ahs (at night, observing the witr with one rak'ahs). When he finished it (the prayer), he would lie down on his right side.

Between the time when the Messenger of Allah (ﷺ) finished the night prayer till the dawn broke, he used to pray eleven rak'ahs, uttering the salutation at the end of every two and observing the witr with a single one, and during that he would make a prostration about as long a one of you would take to recite fifty verses before raising his head. When the mu'adhdhin finished making the call for the dawn prayer, he stood up and prayed two short rak'ahs, then he lay down on his right side till the mu'adhdhin came to him

Some narrators added something more in their version.

Abu Dawud said: Ibn Numair reported it from Hisham recently.

The Messenger of Allah (ﷺ) used to pray thirteen rak'ahs during the night ; he then offered two light rak'ahs of prayer when he heard the call to the dawn prayer.

The Prophet (ﷺ) used to pray thirteen rak'ahs during the night. He would offer eight rak'ahs observing the witr with one rak'ah. Then he prayed (the narrator Muslim said) two rak'ahs after witr prayer in sitting position. When he wished to bow, he stood up and bowed. He used to pray two rak'ahs between the call to the dawn prayer and the iqamah.

How did the Messenger of Allah (ﷺ) pray during Ramadhan ? She said: The Messenger of Allah (ﷺ) did not pray more than eleven rak'ahs during Ramadhan and other than Ramadhan. He would pray four rak'ahs. Do not ask about their elegance and length. He then would pray for rak'ahs. Do not ask about their alegance and length. Then he would pray three rak'ahs. 'Aishah said: I asked: Messenger of Allah, do you sleep before observing witr ? He replied: 'Aishah, my eyes sleep, but my heart does not sleep.

I divorced my wife. I then came to Medina to sell my land that was there so that I could buy arms and fight in battle. I met a group of the Companions of the Prophet (ﷺ). They said: Six persons of us intended to do so (i.e. divorce their wives and purchase weapons), but the Prophet (ﷺ) prohibited them. He said: For you in the Messenger of Allah there is an excellent model. I then came to Ibn 'Abbas and asked him about the witr observed by the Prophet (ﷺ). He said: I point to you a person who is most familiar with the witr observed by the Messenger of Allah (ﷺ). Go to 'Aishah. While going to her I asked Hakim b. Aflah to accompany me. He refused, but I adjured him. He, therefore, went along with me. We sought permission to enter upon 'Aishah. She said: Who is this ? He said: Hakim b. Aflah. She asked: Who is with you ? He replied: Sa'd b. Hisham. She said: Hisham son of 'Amir who was killed in the Battle of Uhud. I said: Yes. She said: What a good man 'Amir was! I said: Mother of faithful, tell me about the character of the Messenger of Allah (ﷺ). She asked: Do you not recite the Quran ? The character of Messenger of Allah (ﷺ) was the Qur'an. I asked: Tell me about his vigil and prayer at night. She replied: Do you not recite: "O thou folded in garments" (73:1). I said: Why not ?

When the opening of this Surah was revealed, the Companions stood praying (most of the night) until their fett swelled, and the concluding verses were not revealed for twelve months from heaven. At last the concluding verses were revealed and the prayer at night became voluntary after it was obligatory. I said: Tell me about the witr of the Prophet (ﷺ). She replied: He used to pray eight rak'ahs, sitting only during the eighth of them. Then he would stand up and pray another rak'ahs. He would sit only after the eighth and the ninth rak'ahs. He would utter salutation only after the ninth rak'ah. He would then pray two rak'ahs sitting and that made eleven rak'ahs, O my son. But when he grew old and became fleshy he observed a witr of seven, sitting only in sixth and seventh rak'ahs, and would utter salutation only after the seventh rak'ah. He would then pray two rak'ahs sitting, and that made nine rak'ahs, O my son. The Messenger of Allah (ﷺ) would not pray through a whole night, or recite the whole Qur'an in a night or fast a complete month except in Ramadan. When he offered prayer, he would do that regularly. When he was overtaken by sleep at night, he would pray twelve rak'ahs.

The narrator said: I came to Ibn 'Abbas and narrated all this to him. By Allah, this is really a tradition. Has I been on speaking terms with her, I would have come to her and heard it from her mouth. I said: If I knew that you were not on speaking terms with her, I would have never narrated it to you.

He (the Prophet( used to pray eight rak'ahs during which he did not sit except the eight rak'ahs. He would sit, make mention of Allah, supplicate Him and then utter the salutation so loudly that we could hear it. He would then pray two rak'ahs sitting after he had uttered the salutation. Then he would pray one rak'ah, and that made eleven rak'ahs, O my son. When the Messenger of Allah (ﷺ) grew old and became fleshy, he offered seven rak'ahs of witr, and then he would pray two rak'ahs sitting after he had uttered the salutation. The narrator narrated the tradition to the same effect till the end.

"He uttered the salutation so loudly that we could hear it."

He uttered the salutation in a way that we could hear it.

Zurarah ibn Awfa said that Aisha was asked about the midnight prayer of the Messenger of Allah (ﷺ).

She said: He used to offer his night prayer in congregation and then return to his family (in his house) and pray four rak'ahs. Then he would go to his bed and sleep, but the water for his ablution was placed covered near his head and his tooth-stick was also kept there until Allah awakened him at night.

He then used the tooth-stick, performed ablution perfectly then came to the place of prayer and would pray eight rak'ahs, in which he would recite Surah al-Fatihah, and a surah from the Qur'an as Allah willed. He would not sit during any of them but sit after the eighth rak'ah, and would not utter the salutation, but recite (the Qur'an) during the ninth rak'ah. Then he would sit and supplicate as long as Allah willed, and beg Him and devote his attention to Him; He would utter the salutation once in such a loud voice that the inmates of the house were almost awakened by his loud salutation. He would then recite Surah al-Fatihah while sitting, bow while sitting, and then recite the Qur'an during the second rak'ah, and would bow and prostrate while sitting. He would supplicate Allah as long as He willed, then utter the salutation and turn away.

This amount of prayer of the Messenger of Allah (ﷺ) continued till he put a weight. During that period he retrenched two rak'ahs from nine and began to pray six and seven rak'ahs standing and two rak'ahs sitting. This continued till he died.

He (the Prophet) would offer the night prayer and go to his bed. In this version there is no mention of praying four rak'ahs. The narrator then transmitted the rest of the tradition. This version further says: He would pray eight rak'ahs during which his recitation of the Qur'an, bowing and prostration were all equal. He would sit only after the eight rak'ah, and then stand up without uttering the salutation, and pray one rak'ah observing witr prayer and then give the salutation raising his voice so much so that we were about to awake. The narrator then transmitted the tradition to the same effect.

He used to lead the people in the 'Isha prayer and return to his family and pray four rak'ahs and go to his bed. The narrator then transmitted the tradition in full. This version does not mention the words: "During them (the rak'ahs) he equated all the recitation of the Qur'an, bowing and recitation." This also does not mention the words about the salutation: "Till he almost awakened us."
