Abu Rafi, who was sent as an envoy from Makkah to the Prophet, became a Muslim in a few days because he was influenced by what he had seen. He wanted to abandon being the envoy of Makkans and wanted to live in Madinah. Hazrat Muhammad (pbuh) did not accept it saying,

“I will not violate the agreement. I will not retain the envoy, either. If you still have the same idea when you return to Makkah, you can come back and we will regard you as one of our brothers.”

Abu Rafi returned to Makkah. Then, he migrated to Madinah and settled there as a Muslim.
