Ubadah bin Umayr bin Ubadah bin Awf (may Allah have mercy on him) said: Abu Ayyub (may Allah be pleased with him) said to me: The Messenger of Allah (peace and blessings be upon him) said to me: "O Abu Ayyub! Shall I not guide you to a charity that Allah and His Messenger love? Make peace between people when they hate one another and their relations have become corrupted."
