It is narrated from Hazrat Abu Saeed Khudri (may Allah be pleased with him) and Hazrat Abu Huraira (may Allah be pleased with him) that the Holy Prophet (peace and blessings of Allah be upon him) said: O Allah, I ask You for a promise which You will never break with me. If, being human, I have caused any harm to a Muslim, or spoken harshly to him, or beaten him, or cursed him, then make it a source of mercy, purification, and nearness to You for him on the Day of Resurrection.
