At this reply of the Holy Prophet, the Christians priests felt stranded, but to keep up appearances, they desired that a Mubahila be held. The Christians named five priests who were to take part in the Mubahila. The Holy Prophet nominated five persons who were to take part in the Mubahila on behalf of the Muslims. These included the Holy Prophet himself, Ali, Fatima, Hasan and Husain. The Holy Prophet did not dominate any of his wives in this behalf. The nomination was confined to such persons who had blood relation with him. The Holy Prophet declared that the Mubahila would be held the following day. At night, the Christians could get no sleep. They felt that truth shone in the eyes of the Holy Prophet and to invoke the curse of God with people like these would invite destruction for the Christians. The following day when the Christian priests waited on the Holy Prophet, they said that they had neither the conviction to profess Islam, nor the strength to enter into any disputation or fight with the Muslims. They said that while maintaining their own faith, they would accept the dominance of the Muslims and pay an annual tribute. The Holy Prophet accepted the offer, entered into a treaty with them, and allowed them to return to Najran. The way in which the Christians gave the challenge of Mubahila in the first instance, and then backed out of it, was a confession of failure on the part of the Christians, and their acknowledgment of the supremacy of Islam as a faith.
