Chapter: The virtue of the regular sunnah prayers before and after the obligatory prayers, and their numbers
Hadith 728 Part A
Umm Habiba (the wife of the Holy Prophet) reported Allah's Messenger (ﷺ) as saying
A house will be built in Paradise, for anyone who prays in a day and a night twelve rak'ahs; and she added: I have never abandoned (observing them) since I heard it from the Messenger of Allah (ﷺ). Some of the other narrators said the same words: I have never abandoned (observing them) since I heard (from so and so).
Hadith 728 Part B
Nu'man b. Salim reported with the same chain of transmitters
He who observed twelve voluntary rak'ahs, a house will be built for him in Paradise.
Hadith 728 Part C
Umm Habiba, the wife of the Messenger of Allah (ﷺ), reported Allah's Messenger (ﷺ) as saying
If any Muslim servant (of Allah) prays for the sake of Allah twelve rak'ahs (of Sunan) every day, over and above the obligatory ones, Allah will build for him a house in Paradise, or a house will be built for him in Paradise; and I have not abandoned observing them after (hearing it from the Messenger of Allah). (So said also 'Amr and Nu'man.)
Hadith 728 Part D
Umm Habiba reported the Messenger of Allah (ﷺ) having said
If any Muslim servant (of Allah) performed ablution, and performed it well, and then observed every day, the rest of the hadith is the same.
Hadith Number 729
Ibn 'Umar reported
I prayed along with Allah's Messenger (ﷺ) two rak'ahs before and two rak'ahs after the noon prayer, two rak'ahs after the sunset prayer and two rak'ahs after the 'Isha' prayer and two rak'ahs after the Friday prayer; and so far as the sunset, 'Isha' and Friday prayers are concerned, I observed (them) along with the Messenger of Allah (ﷺ) in his house.
