It is narrated from Sayyiduna Atiyyah Qarazi (may Allah be pleased with him), he says: I was presented before the Noble Prophet (peace and blessings be upon him) on the day of Qurayzah. When people doubted whether I was mature or not, the Prophet (peace and blessings be upon him) ordered that it be checked whether I had grown pubic hair or not. When they saw that I had not grown these hairs, I was released and included among the captives.

Brief Explanation
Benefits: … On the occasion of the Battle of Khandaq, the Jewish tribe of Banu Qurayza broke their covenant. When the Prophet sallallahu alayhi wa sallam besieged them, they agreed to accept the judgment of Sayyiduna Sa'd bin Mu'adh radi Allahu anhu. He ruled that their men should be killed and their women and children taken captive. Now, in cases where there was doubt about whether a boy had reached puberty or not, the decision would be made by examining the hair under the navel (pubic hair); if it had grown, he would be considered an adult man and killed, otherwise he would be considered a child and spared. From this incident, it is understood that pubic hair is the distinguishing line between puberty and non-puberty. But is this a general law? See the benefits of the last hadith of this chapter.
