Musannaf Ibn Abi Shaybah 35336 — Those whom it is forbidden to kill

Abd al-Malik bin Umayr (may Allah have mercy on him) reports that Sayyiduna Atiyyah al-Qurazi (may Allah be pleased with him) said: On the day of the campaign against Banu Qurayzah we were presented before the Prophet (peace and blessings be upon him). Whoever had grown pubic hair was killed, and whoever had not grown pubic hair had his way left clear.
