It is narrated from Hazrat Dawood bin Husain (may Allah have mercy on him) that among the judges of Madinah Munawwarah, a child named Salamah bin Abdur Rahman Al-Makhzumi gave testimony before one of the judges. Hazrat Salim (may Allah have mercy on him) and Hazrat Qasim (may Allah have mercy on him) were asked about the validity of his testimony. They replied: If some pubic hair has appeared below his navel, then his testimony is valid.
