Musannaf Ibn Abi Shaybah 34123 — Reports on Abu Bakr al-Siddiq

Bistam bin Muslim (may Allah have mercy on him) said: The Messenger of Allah (peace and blessings be upon him) sent Sayyiduna Amr bin al-As (may Allah be pleased with him) as commander of a detachment in which were Sayyiduna Abu Bakr and Sayyiduna Umar (may Allah be pleased with them both). When they returned, Sayyiduna Abu Bakr (may Allah be pleased with him) and Sayyiduna Umar (may Allah be pleased with him) complained about Sayyiduna Amr (may Allah be pleased with him). The Messenger of Allah (peace and blessings be upon him) said: "No one will be made commander over you two after me."
