On the occasion of the Feast of Mab'ath

What was the main reason for Prophet of Islam’s accomplishment in conveying his message?

A great movement was started which could well be said to have divided human history into two eras: the pre-Islamic era, and the post-Islamic era. The Holy Prophet (s.w.a.) pushed humanity forwards, strengthened the bases of morality, and left unforgettable lessons for all humans. You should consider the greatness of Mab'ath from such a perspective.
