Sayyidina Abu Hurayrah reported that Allah’s Messenger said, “When it is the first night of the month of Ramadan, the devils and the rebellious jinns are put in hackles. The gates of Hell are shut and not one of them is opened. And the gates of Paradise are unlocked and none of them is locked. And, an announcer calls, ‘0 seeker of good, come forward. And 0 seeker of evil, desist’. And, freedom from fire is (allowed) by Allah. And, this happens every night”.
