i found this narration:
Abu Huraira's mother, was still a polytheist, He
prayed for her to become a Muslim, but she refused. Sunni sources report:
One day, he again invited his mother to believe in the
One God and
His Prophet. She answered with some bad words about the
Prophet. Abu Hurairah went to the Prophet with tears in his eyes. “Why are you crying, Abu Hurairah?” asked the Prophet. “I always invite my mother to
Islam, and she always refuses,” said Abu Hurairah. “I asked her again today. But she said some things about you that made me sad. Can you pray to Allah for her to turn to Islam?” The Prophet prayed for Abu Hurairah’s mother to accept Islam. When Abu Hurairah went home, he found the door closed. He heard
the splashing of water. He tried to enter the house, but his mother said, “Wait a minute. Don’t come in yet.” Then she got dressed and said, “You can come in now.” When Abu Hurairah went inside, his mother said,
“I declare that there is no god but Allah and that Muhammad is His Servant and Messenger.” Abu Hurairah again went to the Prophet crying. But this time his tears were tears of joy. “I have good news,
Rasul'Allah,” he said. “Allah has answered your
prayer and guided my mother to Islam.”
