Musannaf Ibn Abi Shaybah 36065 — The sending of al-Numan bin Muqarrin

Abd al-Malik bin Umayr said: Sayyiduna Umar (may Allah be pleased with him) wrote in a letter to Sayyiduna Nu'man bin Muqarrin (may Allah be pleased with him): "In battle keep seeking the counsel and help of Sayyiduna Tulayhah and Sayyiduna Amr bin Ma'dikarib (may Allah be pleased with them both), but do not entrust any position of authority to them, for every maker knows best what he has made."
