Beginning of Persecution

At the end of the third year the Prophet received the command to “arise and warn,” whereupon he began to preach in public, pointing out the wretched folly of idolatry in face of the tremendous laws of day and night, of life and death, of growth and decay, which manifest the power of Allah and attest His sovereignty. It was then, when he began to speak against their gods, that Quraysh became actively hostile, persecuting his poorer disciples, mocking and insulting him. The one consideration which prevented them from killing him was fear of the blood-vengeance of the clan to which his family belonged. Strong in his inspiration, the Prophet went on warning, pleading, threatening, while Quraysh did all they could to ridicule his teaching, and deject his followers.
