Arrogance as the Disease of the Heart

Arrogance is identified as the number one disease of the heart. The speaker highlights an incident where an Arab woman questioned why another Arab woman didn't have an Arab friend, emphasizing the notion of superiority and the need to associate only with those from the same background. This arrogance extends beyond Arab communities and can be observed in various settings, such as reserving seats in a mosque or disapproving of a marriage to an African American Muslim. The speaker emphasizes that breaking down these barriers was one of the first achievements of Islam and encourages humility and acceptance in the Muslim community.
