Banu Thaqif
A year after the Battle of Tabuk, the Banu Thaqif sent emissaries to surrender to Muhammad and adopt Islam. Many bedouins submitted to Muhammad to safeguard against his attacks and to benefit from the spoils of war. However, the bedouins were alien to the system of Islam and wanted to maintain independence: namely their code of virtue and ancestral traditions. Muhammad required a military and political agreement according to which they "acknowledge the suzerainty of Medina, to refrain from attack on the Muslims and their allies, and to pay the Zakat, the Muslim religious levy."
