"Indeed We have revealed it (Qur'an) in the night of Power. And what will explain to you what the night of Power is? The night of Power is better than a thousand months.

Abu Umamah reported: "I came to the Messenger of Allah and said: 'Order me to do a deed that will allow me to enter Paradise.' He said: 'Stick to fasting, as there is no equivalent to it.' Then I came to him again and he said: 'Stick to fasting."' [Ahmad, an-Nasa'i, and al-Hakim].
Sahl ibn Sa'd reported that the Prophet salla Allahu alaihi wa sallam said: "There is a gate to Paradise that is called ar-Rayyan. On the Day of Resurrection it will say: 'Where are those who fasted?' When the last [one] has passed through the gate, it will be locked." [al-Bukhari and Muslim].
`Abdullah ibn `Amr reported that the Messenger of Allah, salla Allahu alaihi wa sallam, said: "The fast and the Qur'an are two intercessors for the servant of Allah on the Day of Resurrection. The fast will say: 'O Lord, I prevented him from his food and desires during the day. Let me intercede for him.' The Qur'an will say: 'I prevented him from sleeping at night. Let me intercede for him.' And their intercession will be accepted." [Ahmad]
