Abu Kathir Suhaimi (may Allah have mercy on him) says that I heard Sayyiduna Abu Hurairah (may Allah be pleased with him) saying: Whoever among the Jews or Christians came to know of my knowledge, he loved me. My mother (was a Christian), and I wanted her to accept Islam but she refused. (One day) I invited her to Islam, but as usual, she refused. I went to the service of the Noble Prophet (peace and blessings be upon him) and requested him to pray for my mother. The Prophet (peace and blessings be upon him) prayed. Then I went to her (my respected mother), and she had closed the door. From inside, she said: "Abu Hurairah, I have become a Muslim!" I informed the Noble Prophet (peace and blessings be upon him) of this and requested: Please pray for me and my mother. The Prophet (peace and blessings be upon him) prayed: "O Lord! Make Your servant Abu Hurairah and his mother beloved among the people."
