Who was slaughtered by a companion of Muhammad in 632?
Khalid ibn al-Walid Abū Sulaymān Khālid ibn al-Walīd ibn al-Mughīrah al-Makhzūmī (Arabic: أبو سليمان خالد بن الوليد بن المغيرة المخزومي‎ ‎ ‎; 585–642), also known as Sayf ullah al-Maslūl (Arabic: سيف الله المسلول‎ ‎ ; "Drawn Sword of God"), was a companion of Muhammad. He is noted for his military tactics and prowess, commanding the forces of Medina under Muhammad and the forces of his immediate successors of the Rashidun Caliphate, Abu Bakr and Umar ibn Khattab. It was under his military leadership that Arabia, for the first time in history, was united under a single political entity, the Caliphate. Commanding the forces of the nascent Islamic state, Khalid was victorious in over a hundred battles, against the forces of the Byzantine-Roman Empire, Sassanid-Persian Empire, and their allies, in addition to other Arab tribes. His strategic achievements include the conquest of Arabia during the Ridda Wars, Persian Mesopotamia and Roman Syria within several years from 632 to 636. He is also remembered for his decisive victories at Yamamah, Ullais, and Firaz, and his tactical successes at Walaja and Yarmouk.
Ridda wars The Ridda wars (Arabic: حروب الردة), also known as the Wars of Apostasy, were a series of military campaigns launched by the Caliph Abu Bakr against rebel Arabian tribes during 632 and 633 AD, just after Muhammad died. The rebels' position was that they had submitted to Muhammad as the prophet of God, but owed nothing to Abu Bakr. Some rebels followed either Tulayha or Musaylima or Sajjah, all of whom claimed prophethood. Most of the tribes were defeated and reintegrated into the Caliphate. The peoples surrounding Mecca did not revolt.
