Read all Ahadith in prayer (kitab al-salat): voluntary prayers by sunan abu dawood

Narrated Umm Habibah: The Prophet صلی ‌اللہ ‌علیہ ‌وسلم 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).

Narrated Abdullah bin Shaqiq: I asked Aishah about the voluntary prayers offered by the Messenger of Allah صلی ‌اللہ ‌علیہ ‌وسلم. She replied: Before the noon prayer he would pray four rak'ahs in my house, then go out and lead the people in prayer, then return to my house and pray two rak'ahs. He would lead the people in the sunset prayer, then return to my house and pray two rak'ahs. Then he would lead the people in the night prayer, and enter my house and pray two rak'ahs. He would pray nine rak'ahs during the night, including witr (prayer). At night he would pray for a long time standing and for a long time sitting. When he recited the Quran while standing, he would bow and prostrate himself from the standing position, and when he recited while sitting, he would bow and prostrate himself from the sitting position, and when dawn came he prayed two rak'ahs, then he would come out and lead the people in the dawn prayer.

Narrated Abdullah bin Umar: The Messenger of Allah صلی ‌اللہ ‌علیہ ‌وسلم would pray two rak'ahs before and two after the noon prayer, two after the sunset prayer in his house, and two after the night prayer. He would not pray afte the Friday prayer till he departed. He would then pray two rak'ahs.

Narrated Aishah: The Prophet صلی ‌اللہ ‌علیہ ‌وسلم never omitted four rak'ahs before the noon prayer, and two rak'ahs before the dawn prayer.

Narrated Aishah: The Messenger of Allah صلی ‌اللہ ‌علیہ ‌وسلم was more particular about observing the supererogatory rak'ahs before the dawn prayer than about observing any of the other supererogatory prayers.

Narrated Aishah: The Prophet صلی ‌اللہ ‌علیہ ‌وسلم would pray two rak'ahs before the dawn prayer lightly so much so that I would say: Did he recite Surah al-Fatihah in them.

Narrated Abu Hurairah: The Prophet صلی ‌اللہ ‌علیہ ‌وسلم would recite in both rak'ahs of the dawn prayer: Say, O unbelievers and Say: He is Allah, the one

Narrated Bilal: Ziyadah al-Kindi reported on the authority of Bilal that he (Bilal) came to the Messenger of Allah صلی ‌اللہ ‌علیہ ‌وسلم to inform him about the dawn prayer. Aishah kept Bilal engaged in a matter which she asked him till the day was bright and it became fairly light. Bilal then stood up and called him to prayer and called him repeatedly. The Messenger of Allah صلی ‌اللہ ‌علیہ ‌وسلم did not yet come out. When he came out, he led the people in prayer and he (Bilal) informed him that Aishah had kept him engaged in a matter which she asked him till it became fairly light; hence he became late in reaching him (in time). He (Bilal) said: Messenger of Allah, the dawn became fairly bright. He said: If the dawn became brighter than it is now, I would pray them (the two rak'ahs of the sunnah prayer), offer them well and in a more beautiful manner.

Narrated Abu Hurairah: The Prophet صلی ‌اللہ ‌علیہ ‌وسلم said: Do not omit them (the two rak'ahs before the dawn prayer) even if you are driven away by the horses.

Narrated Abdullah bin Abbas: The Messenger of Allah صلی ‌اللہ ‌علیہ ‌وسلم used to recite in both rak'ahs of the dawn prayer: Say: We believe in Allah and in the revelation given to us (3: 84). This is in the first rak'ah and in the second rak'ah (he recited): We believe in Allah and bear witness that we submit ourself (to Him). (3: 52).
