“Our Prophet (peace be upon him) and his followers were always peaceful [at Mecca], despite suffering unprovoked abuse and attacks by the polytheists”
The Muslims were actually the first to resort to physical violence, when Sa’d bin Abu Waqqas picked up a camel’s jawbone and struck a local polytheist who was “rudely interrupting” his group of praying Muslims. “This was the first blood to be shed in Islam” (Ibn Ishaq/Hisham 166).
The new converts were quite aggressive, particularly when they could get away with it, which was the misfortune of others. An example is when one of the strongest Muslims, Hamza, struck a Meccan leader by the name of Abu Jahl ‘violently” with his bow for speaking in an insulting way to Muhammad:
Although Abu Jahl did not retaliate against the more powerful man at the time, he later mistreated his Muslim slaves, almost certainly as a consequence of his public humiliation.
The Muslims would later be the first to declare war at Mecca, and were subsequently evicted. Even then, they were the first to renew hostilities as Muhammad ordered deadly raids against Meccan caravans from his new home in Medina.
