It is narrated from a Companion (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: In the month of Ramadan, the gates of the heavens are opened and the gates of Hell are closed, and every rebellious devil is chained. And every night a caller announces: O seeker of good! Advance, and O seeker of evil! Refrain, until Ramadan comes to an end.
