No one is better in word than who called to the monotheism of Allah and His worship alone and performed a righteous deed and said: "Indeed I am from the Muslims yielded for the command of Allah and His law." And in the verse is encouragement on the call to Allah Glorified be He, and a clarification of the merit of the scholars calling to Him upon an insight, according to what came from the Messenger of Allah Muhammad peace and blessings of Allah be upon him.
