He was a mercy not just to believers, but to disbelievers as well, for he would invite them to come out of darkness and into the light of true guidance. He is a favor and blessing for mankind, not just the Arabs, the people among whom he was sent, but for people of all races and colors. His staunchest enemies became his closest followers when the cloud of blind prejudice was removed from their sight and when they were able, for the very first time, to see with clarity the true nature of the Prophets character.
