Musannaf Ibn Abi Shaybah 35980 — The account of al-Yamamah and those

Urwah said: When people of Banu Sulaym began to apostatize, Sayyiduna Abu Bakr (may Allah be pleased with him) sent Sayyiduna Khalid bin al-Walid (may Allah be pleased with him) to them with an army. There he gathered the people in one place and set fire to them. When Sayyiduna Umar (may Allah be pleased with him) learned of this, he came to Sayyiduna Abu Bakr (may Allah be pleased with him) and said to him: "You should remove from command a man who inflicts the punishment that is the right of Allah!" Sayyiduna Abu Bakr (may Allah be pleased with him) said: "By Allah, I cannot sheathe such a sword of Allah until Allah Almighty Himself sheathes His sword." Then Sayyiduna Abu Bakr (may Allah be pleased with him) ordered Sayyiduna Khalid bin al-Walid (may Allah be pleased with him) to go against Musaylimah.
