Nadr bin Anas, may Allah have mercy on him, says that during the incident of Harrah, when the children of Hazrat Anas, may Allah be pleased with him, and people of his tribe were martyred, Hazrat Zaid bin Arqam, may Allah be pleased with him, wrote him a letter of condolence and said: I give you glad tidings from Allah. I heard the Prophet Muhammad, peace and blessings be upon him, say: O Allah! Forgive the Ansar, their sons, and their grandsons, and forgive the women of the Ansar, the women of their sons, and the women of their grandsons.
