Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates that the Prophet Muhammad (peace and blessings be upon him) said: "When the first night of the month of Ramadan comes, the devils, that is, the rebellious jinn, are chained. The doors of Hell are closed and none of its doors remain open. The doors of Paradise are opened and none of its doors remain closed. And a caller announces: O seeker of good, come forward! O seeker of evil, desist! Allah frees some people from the Fire, and this happens every night."
