It is narrated from Hazrat Jarir (may Allah be pleased with him) that at the time of accepting Islam, I presented myself in the court of the Messenger and said, "O Messenger of Allah! I pledge allegiance to Islam." The Noble Prophet (peace and blessings be upon him) withdrew his hand and said, "Show goodwill to every Muslim." Then the Noble Prophet (peace and blessings be upon him) said, "Whoever does not show mercy to people, Allah Almighty does not show mercy to him."
