what prophet said about ramdan?

“In Paradise there is a gate called al-Rayyaan, through which those who used to fast will enter on the Day of Resurrection, and no one but they will enter it. It will be said, ‘Where are those who fasted?’ They will get up, and none will enter it but them. When they have entered, it will be locked, and no one else will enter.” (al-Bukhaari, 1763; Muslim, 1947).

It was narrated from Abu Salamah that Abu Hurayrah said: “The Messenger of Allaah (peace and blessings of Allaah be upon him) said: ‘Whoever fasts Ramadaan out of faith and seeking reward, his previous sins will be forgiven.’” (Narrated by al-Bukhaari, al-Eemaan, 37).

It was narrated that Abu Hurayrah (may Allaah be pleased with him) said: “The Messenger of Allaah (peace and blessings of Allaah be upon him) said: ‘Allaah says: “Every deed of the son of Adam is for him, except for fasting; it is for Me and I shall reward for it.” Fasting is a shield and when one of you is fasting he avoid sexual relations with his wife and quarreling. If somebody should fight or quarrel with him, he should say, ‘I am fasting.’ By the One in Whose hand is my soul, the unpleasant smell coming out from the mouth of a fasting person is better in the sight of Allaah than the smell of musk. The fasting person will have two moments of joy: one when he breaks his fast, and the other when he meets his Lord; then he will be pleased because of his fasting.’” (Narrated by al-Bukhaari, 1771)

In the saheeh ahaadeeth it says that there are eight gates:

It was narrated from Sahl ibn Sa’d (may Allaah be pleased with him) that the Prophet (peace and blessings of Allaah be upon him) said: “In Paradise there are eight gates, among which is a gate called al-Rayyaan, which none will enter but those who fast.” (Narrated by al-Bukhaari, 3017).

It was narrated from ‘Ubaadah (may Allaah be pleased with him) that the Prophet (peace and blessings of Allaah be upon him) said: “Whoever bears witness that there is no god but Allaah alone, with no partner or associate, and that Muhammad is His slave and Messenger, and that ‘Eesa (Jesus) is the slave of Allaah and His Messenger, and a word which Allaah bestowed on Maryam and a spirit created by Him (cf. al-Nisa’ 4:171), and that Paradise is true and Hell is true, will have the right to be admitted by Allaah to Paradise through whichever of the eight gates he wishes, because of his good deeds.” (Narrated by al-Bukhaari, 3180; Muslim, 41)

It was narrated from Abu Hurayrah (may Allaah be pleased with him) that the Prophet (peace and blessings of Allaah be upon him) said: “When Ramadaan begins, the gates of Paradise are opened and the gates of Hell are closed, and the devils are chained up.”

(Narrated by al-Bukhaari, 3035; Muslim 1793)
