Volume 003, Book 032, Hadith Number 226Narrated By Abu Huraira :
I heard Allah's Apostle saying regarding Ramadan, "Whoever prayed at night in it (the month of Ramadan) out of sincere Faith and hoping for a reward from Allah, then all his previous sins will be forgiven."
Volume 003, Book 032, Hadith Number 227Narrated By Abu Huraira :
Allah's Apostle said, "Whoever prayed at night the whole month of Ramadan out of sincere Faith and hoping for a reward from Allah, then all his previous sins will be forgiven." Ibn Shihab (a sub-narrator) said, "Allah's Apostle died and the people continued observing that (i.e. Nawafil offered individually, not in congregation), and it remained as it was during the Caliphate of Abu Bakr and in the early days of 'Umar's Caliphate." 'Abdur Rahman bin 'Abdul Qari said, "I went out in the company of 'Umar bin Al-Khattab one night in Ramadan to the mosque and found the people praying in different groups. A man praying alone or a man praying with a little group behind him. So, 'Umar said, 'In my opinion I would better collect these (people) under the leadership of one Qari (Reciter) (i.e. let them pray in congregation!)'. So, he made up his mind to congregate them behind Ubai bin Ka'b. Then on another night I went again in his company and the people were praying behind their reciter. On that, 'Umar remarked, 'What an excellent Bid'a (i.e. innovation in religion) this is; but the prayer which they do not perform, but sleep at its time is better than the one they are offering.' He meant the prayer in the last part of the night. (In those days) people used to pray in the early part of the night."
Volume 003, Book 032, Hadith Number 228Narrated By 'Aisha :
(The wife of the Prophet) Allah's Apostle used to pray (at night) in Ramadan.
Volume 003, Book 032, Hadith Number 229Narrated By 'Urwa :
That he was informed by 'Aisha, "Allah's Apostle went out in the middle of the night and prayed in the mosque and some men prayed behind him. In the morning, the people spoke about it and then a large number of them gathered and prayed behind him (on the second night). In the next morning the people again talked about it and on the third night the mosque was full with a large number of people. Allah's Apostle came out and the people prayed behind him. On the fourth night the Mosque was overwhelmed with people and could not accommodate them, but the Prophet came out (only) for the morning prayer. When the morning prayer was finished he recited Tashah-hud and (addressing the people) said, "Amma ba'du, your presence was not hidden from me but I was afraid lest the night prayer (Qiyam) should be enjoined on you and you might not be able to carry it on." So, Allah's Apostle died and the situation remained like that (i.e. people prayed individually)."
Volume 003, Book 032, Hadith Number 230Narrated By Abu Salama bin 'Abdur Rahman :
That he asked 'Aisha "How was the prayer of Allah's Apostle in Ramadan?" She replied, "He did not pray more than eleven Rakat in Ramadan or in any other month. He used to pray four Rakat... let alone their beauty and length... and then he would pray four... let alone their beauty and length... and then he would pray three Rakat (Witr)." She added, "I asked, 'O Allah's Apostle! Do you sleep before praying the Witr?' He replied, 'O 'Aisha! My eyes sleep but my heart does not sleep."
Volume 003, Book 032, Hadith Number 231Narrated By Abu Huraira :
The Prophet said, "Whoever fasted the month of Ramadan out of sincere Faith (i.e. belief) and hoping for a reward from Allah, then all his past sins will be forgiven, and whoever stood for the prayers in the night of Qadr out of sincere Faith and hoping for a reward from Allah, then all his previous sins will be forgiven."
