Why were so many bedouins against muhammad's preaching?

Muhammad’s message of monotheism does not adequately explain why the leaders of the Quraysh rejected his message so forcefully. Indeed, Muhammad preached a lot more than this: he called for a top-to-bottom reform of Meccan society, advocating for the rights of the poor and weak. While it is also true that Muhammad’s renouncement of the pagan gods was unbearable to many followers of the old religion, so too did his powerful critique of the rich and powerful set him on a collision course against them.
