Uthman ibn Huwairith
Uthman ibn Huwairith was one of the four major hanifs during the time of the Islamic prophet Muhammad.
Uthman eventually accepted Christianity and remained Christian until he died. It is unknown whether he heard Muhammad's message. It was said that he left the area most likely before the birth of Muhammad. This is because he left around the time Waraqah was in his 20s.
He traveled to Rome and eventually became an interpreter. It is mentioned that because of this he eventually accepted Christianity, and held a substantial position amongst the society in Rome.
