‘Abd Al-Rhaman Ibn Nasr ibn ‘Abdallah ibn Muhammad al-Nabarawi al-Shafi’i (al-Adawi al-Shairazi);
is an Egyptian scholar who flourished probably in the time of Salahuddin (sultan 1169-1193). He wrote a handbook for the use of police officers in charge of markets (muhtasib; hence, Spanish almotacen; their function was called hisba), enabling them for instance to verify weights and measures and to test the genuineness of wares.
