The Prophet Sallam's Allegiance to the People of Najd

The Prophet Sallam chose 70 of the best preachers from Ahlazsofah to go and preach in Najd. They were known for their charity work, even though they didn't have a house. This is what we call Hulafah or Halif, right? That your Halif you have a treaty. So he did not realize at the time that one of the other chieftains hated Islam so much that he was willing to invoke a civil war basically.
