Prophet Muhammad's (Peace be upon him) march had a great deal of an impact on Makkah. Some people of Makkah, didn't believe in one god, and hurt Prophet Muhammad (Peace be upon him) and his Sahbah (companions). But they didn't give up, and kept preaching Islam, even though the Quershay would hurt them so much, they would throw rocks on them while they were Praying, yet they didn't give up!
