[Machine] A man was born with a son during the time of the Prophet ﷺ. He brought the child to the Prophet ﷺ who took hold of the skin of his forehead and prayed for blessing upon him. A strand of hair grew on his forehead in the shape of an arch, and the boy grew up. When the time of the Khawarij came, he loved them and the strand of hair on his forehead fell off. His father took hold of him, tied him up, and confined him, fearing that he would join them. We went to him, admonished him, and said to him: "Did you not see that the blessings of the Prophet's supplication have fallen from your forehead?" We continued with this until he changed his mind. Allah then returned the strand of hair to his forehead, and he repented.
