Why did quraish think that holy prophet would favour them?

The Quraish believed that the Holy Prophet Muhammad would favor them because he belonged to their tribe, the Quraysh, which was a respected and influential clan in Mecca. They thought that his leadership and prophetic mission would naturally align with their interests, as they were the custodians of the Kaaba and held significant social and economic power in the region. Additionally, they viewed his message as potentially reinforcing their status rather than challenging it. However, as his teachings promoted monotheism and social justice, they eventually felt threatened by his message.
