It is narrated from Hazrat Abu Hurairah (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: There are three persons whose supplication is never rejected: a just ruler, a fasting person until he breaks his fast, and the supplication of the oppressed. It rises above the clouds, the gates of the heavens are opened for it, and Allah, the Exalted, says: By My honor, I will surely help you, even if it is after some time.
