Hazrat Abu Saeed (may Allah be pleased with him) narrates from Abu Huraira (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: O Allah! I make a covenant with You which You will never break with me. I am also a human being. O Allah! If I have ever caused harm to anyone (unknowingly), or struck someone with a whip, or uttered abuse or curse, then make it a means of purification and mercy for that person, and on the Day of Resurrection, make it a cause for Your closeness.
