Mujahid narrates: I heard a man in the mosque of Kufa saying: The day when Sayyiduna Sa’d bin Mu’adh (may Allah be pleased with him) was appointed as arbitrator regarding Banu Qurayza, I was a young boy. They doubted whether I had reached puberty, so they examined me and did not find pubic hair on me, and for this reason, I was spared.
