Mukhtasar Bukhari

Sahih Sahl (may Allah be pleased with him) narrates from the Noble Prophet (peace and blessings of Allah be upon him) that he said: "In Paradise, there is a gate called 'Rayyan.' On the Day of Resurrection, only those who fast will enter through it; no one else will enter through that gate. It will be announced: 'Where are those who fasted?' Then they will stand up, and no one except them will enter through that gate. When they have entered, the gate will be closed, and no one else will enter through it."

Narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) said: "Whoever spends two pairs (of clothes or any two things) in the way of Allah will be called from the gates of Paradise (the angels will say): O servant of Allah! This gate is good (enter through it). Then whoever is among those who establish prayer will be called from the gate of prayer, and whoever is among those who strive in jihad will be called from the gate of jihad, and whoever is among those who fast will be called from 'Bab al-Rayyan (Rayyan)', and whoever is among those who give charity will be called from the gate of charity." So Sayyiduna Abu Bakr al-Siddiq (may Allah be pleased with him) said: "O Messenger of Allah! May my parents be sacrificed for you, whoever is called from all these gates will have no further need (left). Will anyone be called from all these gates?" The Prophet (peace and blessings of Allah be upon him) said: "Yes! And I hope that you will be among them."

Narrated from Sayyiduna Abu Huraira (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) said: "When Ramadan comes, the gates of Paradise are opened."

Sayyiduna Abu Hurairah (may Allah be pleased with him) in another narration says that the Messenger of Allah (peace and blessings of Allah be upon him) said: "When Ramadan comes, the doors of the sky (that is, Paradise) are opened and the doors of Hell are closed, and the devils are chained with the strongest chains."
