Abu Hurairah narrated that: the Messenger of Allah said: “On the first night of the month of Ramadan, the Shayatin are shackled, the jinn’s are restrained, and the gates of the Fires are shut such that no gate among them would be opened. The gates of Paradise are opened such that no gate among them would be closed, and a caller calls: ‘O seeker of the good; come near!’ and ‘O seeker of evil; stop! For there are those whom Allah frees from the Fire.’ And that is every night.” (Jami at-Tirmidhi: 682, Sunnah.com reference: Book 7, Hadith 5)
