Musnad Ahmad 1092:1

Isma'il narrated to us, from 'Uthman al-Batti, from 'Abd al-Hamid ibn Salamah, from his father, from his grandfather, that his parents disputed over him before the Prophet, peace and blessings of Allah be upon him, and one of them was a Muslim and the other was a disbeliever. He gave him the choice, so he turned toward the disbeliever among them. He (the Prophet) said: "O Allah, guide him." Then he turned toward the Muslim, so he (the Prophet) judged him to him.
