And the Messenger of Allah, peace and blessings be upon him, said: "There are three types of people whose supplication is not rejected: the fasting person until he breaks his fast, the just ruler, and the supplication of the oppressed. Allah raises it above the clouds, and the gates of the heavens are opened for it. Then the Lord, Blessed and Exalted, says: By My Honor! I will surely help you, even if after some time."
