Musannaf Ibn Abi Shaybah 22329 — Testimony of children

It is narrated from Dawud bin al-Husayn (may Allah have mercy on him) that a boy testified before one of the judges of Madinah, who was named Salamah bin Abd al-Rahman al-Makhzumi. He sent to Salim (may Allah have mercy on him) and al-Qasim (may Allah have mercy on him) and asked them about his testimony, and they said: If he has grown some pubic hair, his testimony is valid.
