Ibn Abi Al-Huqaiq was despatched to the Messenger of Allâh [pbuh] to negotiate the surrender treaty. The Prophet [pbuh] agreed to spare their lives on condition they evacuate Khaibar and the adjacent land, leaving whatever gold and silver they had in their possession. However, he stipulated that he would disavow any commitment if they concealed anything. Shortly afterwards, the forts were handed over to the Muslims and all Khaibar was reduced and brought under the sway of Islam.
This treaty notwithstanding, Abi Al-Huqaiq’s two sons concealed a leather bag full of jewels, and money belonging to Huyai bin Al-Akhtab, who carried it with him when Banu Nadir had been banished. Kinanah bin Ar-Rabi‘, who had hidden the musk somewhere, was obdurate in his denial and so he was killed when the musk was discovered and his dishonesty was proven. Abi Al-Huqaiq’s two sons were killed in recompense for breaching the covenant, and Safiyah, Huyai’s daughter was taken as a captive.
