“I heard 'Atiyyah Al-Quradhi say: 'We were presented to the Messenger of Allah ﷺ on the Day of Quraidhah. Those whose pubic hair had grown were killed, and those whose pubic hair had not yet grown were let go. I was one of those whose pubic hair had not yet grown, so I was let go.” (Using translation from Ibn Mājah 2541)
