Musannaf Ibn Abi Shaybah 40714 — Reports on the Khawarij

Sayyiduna Abu al-Tufayl (may Allah be pleased with him) said: A boy was born in the time of the Messenger of Allah (peace and blessings be upon him). He prayed for him, took hold of the skin of his forehead and did like this, pressed his forehead and prayed for blessing for him. The narrator said: A hair like the coarse hair of a horse grew on the boy's forehead. Then the boy grew up, and when the time of the Khawarij came, he inclined towards the Khawarij. Then that hair fell from his forehead. His father seized him and tied him up, because he feared that he would join the Khawarij. We met him once, admonished him and said to him: "Do you not see that the blessing of the Messenger of Allah (peace and blessings be upon him) has fallen from your forehead?" We kept on counselling him in this way until he turned back from his opinion. Then Allah Almighty returned the hair to his forehead, and he repented and reformed himself.
