And prayers and peace be upon our Prophet Muhammad, and upon his family and all his Companions.

The reader: In the name of Allah, the Most Gracious, the Most Merciful.
Praise be to Allah, Lord of the worlds, and may peace and blessings be upon our Prophet Muhammad, and upon his family and all his Companions:
The author (may Allah have mercy on him) transmitted, in the context of the hadiths in the chapter on the virtue of standing in night prayer: "From Aisha (may Allah be pleased with her):

The Messenger of Allah (ﷺ) used to perform eleven Rak'ah (of Tahajjud) prayers at night. He (ﷺ) would prostrate so long as one of you might recite fifty Ayat (of the Qur'an). Thereafter, he would perform two Rak'ah before Fajr prayers and would lie down on his right side till the Mu'adhdhin would come and inform him about the time of (Fajr) prayer.

أن رسول الله صلى الله عليه وسلم كان يصلي إحدى عشرة ركعة -تعني في الليل- يسجد السجدة من ذلك قدر ما يقرأ أحدكم خمسين آية قبل أن يرفع رأسه، ويركع ركعتين قبل صلاة الفجر، ثم يضطجع على شقه الأيمن حتى يأتيه المنادي للصلاة

Riyad as-Salihin 1171

Al-Bukhari narrated it.
And from her (may Allah be pleased with her), she said:

The Messenger of Allah (peace and blessings be upon him) did not exceed eleven rak'ahs — in Ramadan or otherwise: he would pray four, so do not ask about their beauty and length! Then he would pray four, so do not ask about their beauty and length! Then he would pray three. I said: O Messenger of Allah, do you sleep before you pray the witr? He said: O Aisha, my eyes sleep, but my heart does not sleep.

ما كان رسول الله صلى الله عليه وسلم يزيد - في رمضان ولا في غيره - على إحدى عشرة ركعة : يصلي أربعًا فلا تسأل عن حسنهن وطولهن ! ثم يصلي أربعًا فلا تسأل عن حسنهن وطولهن ! ثم يصلي ثلاثًا. فقلت : يا رسول الله أتنام قبل أن توتر !؟ فقال : يا عائشة إن عيني تنامان ولا ينام قلبي

Sunan Abi Dawud 1341Sahih (Al-Albani)

Agreed upon by al-Bukhari and Muslim.
And from her (may Allah be pleased with her):

The Prophet (ﷺ) would sleep during the early part of night and stand in Salat during the latter part.

أن النبي صلى الله عليه وسلم كان ينام أول الليل ويقوم آخره فيصلي

Agreed upon by al-Bukhari and Muslim.
And from Ibn Mas'ud (may Allah be pleased with him) he said:

One night I joined the Prophet (ﷺ) in his (optional) Salat. He (ﷺ) prolonged the Qiyam (standing) so much that I made up my mind to commit an act of wrong. He was questioned: "What did you intend to do?" He replied: "I intended to sit down and stop following him (in Salat)."

صليتُ مع النبي صلى الله عليه وسلم ليلة، فلم يزل قائمًا حتى هممت بأمر سوء ، قيل : ما هممت ؟ قال : هممت أن أجلس وأدعه

Agreed upon by al-Bukhari and Muslim.
And from Hudhayfah (may Allah be pleased with him) he said:

Hudhaifah (May Allah be pleased with him) reported: I performed Salat with the Prophet (ﷺ) one night, and he started reciting Surat Al- Baqarah. I thought that he would go in Ruku' (bowing posture in Salat) at the end of one hundred Ayat, but he continued (reciting); and I thought that he would perhaps recite (this Surah) in the whole Rak'ah (prayer), but he continued the recitation; I thought he would perhaps bow on completing (this Surah). He (ﷺ) then started reciting Surat An-Nisa' which he followed with Surat Al-Imran. He recited leisurely. When he recited an Ayah which mentioned the tasbeeh, he would say Subhan Allah and when he recited the Ayah which tells how the Rubb is to be asked, the Messenger of Allah (ﷺ) would then ask from Him; and when he (ﷺ) recited an Ayah asking one to seek Protection Allah, he would seek Protection of Allah. Then he bowed and said, "Subhana Rabbiyal-Azim (My Rubb the Great is free from imperfection)"; his bowing lasted about the same length of time as his standing, (and then on returning to the standing posture after Ruku') he would say, "Sami' Allahu liman hamidah, Rabbana lakal-hamd (Allah listens to him who praises Him. Praise be to You, Our Rubb!)," and he would then stand about the same length of time as he had spent in bowing. He would then prostrate himself and say, "Subhana Rabbiyal-A'la (My Rubb the Supreme is free from imperfection)," and his prostration lasted nearly the same length of time as his standing (Qiyam). [Muslim] .

صليتُ مع النبي صلى الله عليه وسلم ذات ليلة فافتتح البقرة، فقلت : يركع عند المائة، ثم مضى، فقلت : يصلي بها في ركعة، فمضى، فقلت : يركع بها، ثم افتتح النساء فقرأها، ثم افتتح آل عمران فقرأها، يقرأ مترسلا، إذا مر بآية فيها تسبيح سبَّح، وإذا مرَّ بسؤال سأل، وإذا مرَّ بتعوذ تعوذ، ثم ركع، فجعل يقول : سبحان ربي العظيم، فكان ركوعه نحوًا من قيامه، ثم قال : سمع الله لمن حمده، ربنا لك الحمد، ثم قام طويلا قريبا مما ركع، ثم سجد فقال : سبحان ربي الأعلى، فكان سجوده قريبًا من قيامه

The Shaykh : In the name of Allah, the Most Gracious, the Most Merciful:
These are hadiths explaining the prayer of the Prophet (peace and blessings be upon him and his family) at night: among them is the first hadith of Aisha: : and he explained this in detail in other hadiths: that he would say the taslim from two rak'ahs, then two rak'ahs, then two rak'ahs, then two rak'ahs, then two rak'ahs, then one rak'ah, meaning he would pray eleven rak'ahs, saying the taslim from every two and completing the prayer with one, and then the Messenger of Allah (peace and blessings be upon him)
