Hadith.2255 - The Messenger of Allah (swt), peace and blessings be upon him and his family, said: "There are four whose supplications are not rejected until the gates of the heavens are opened for them and their prayers reach the Throne: the supplication of a parent for their child, the supplication of the wronged against the one who wronged them, the supplication of the one performing Umrah until they return, and the supplication of the fasting person until they break their fast."
