Mujahid (may Allah have mercy on him) says that Ayyash bin Abi Rabi'ah (may Allah be pleased with him) accepted Islam and emigrated to the Prophet (peace and blessings be upon him). Then his maternal half-brother Abu Jahl bin Hisham came to him along with another man, and they said to him: Your mother adjures you by her kinship and her right that you return to her. So Sayyiduna Ayyash bin Abi Rabi'ah (may Allah be pleased with him) went back with them, and they tied him up, brought him to Makkah and subjected him to all kinds of torment.
