We know the Prophet had dispatched an army against tribes lying along the border with Syria, that was ruled by Byzantine empire. The tribes had shown tendencies of hostilities and at times had ridiculed the Prophet.
Usama had to return then due to the Prophet’s illness. The Caliph wanted to finish the task, the Prophet left uncompleted. He wished to conclude it on any condition. He went against the suggestions of close companions and sent an expedition.
Usama won and returned with momentous bounty.
Bedouin Attack on Madinah
There were few tribes that had accepted Islam but were reluctant to follow it after the death of the Prophet. They believed Madinah was defenseless and knew most of the warriors were with Umar, who had still not returned.
Few of them were incited by the false prophet of Najd. Some other were wary of giving Zakat and Jizya. But the caliph was adamant and maintained nothing be altered in what the Prophet had left behind.
Abu Bakr had already readied his men for any attack that might come.
The Bedouins finally attached but were defeated in both the Battle of Dhu’l-Qassa and Battle of Rabadha.
The battles further cemented Islam’s grip over smaller tribes of Arabia.
Abu Bakr’s determination had proved to be strategic and against all odds he stifled the opposition with little or no loss.
