Answer:
Turn against.
Step-by-step explanation:
The clans turn against Islam and Muhammed (S. A. W) after hearing Islam's message by Muhammad (S. A. W) because they can't tolerate any statement against their ancestor's religion. The message of Muhammad (S. A. W) is that there is no God but Allah, and that life should be lived in complete submission to the will of Allah and prevent them from preaching their ancestor's religion which turn against Islam and Muhammad (S. A. W).
