Prophet Muhammad (Muhammad) - The Majority of Mecca Becomes Islamic

Hitherto no prohibition had been enforced against idolaters entering the Holy Ka'ba, or performing their abominable rites within the sacred precincts. Towards the end of the ninth year of the hijrah, during the month of pilgrimage Ali was delegated by the Prophet to read a proclamation that ran as follows: "No idolater shall after this year perform the pilgrimage; no one shall make the circuit of the Ka'ba naked (such a disgraceful custom was practiced by the pagan Arabs); any treaty with the Prophet shall continue in force but four months are allowed to every man to return to his territories; after that there will be no obligation on the Prophet, except towards those with whom treaties have been concluded."

The vast multitude who had listened to the above declaration returned to their homes, and before the following year was over the majority of them were Muslims.

Muhammad Accomplishes His Mission
Thus, the mission of the Prophet Muhammad was now accomplished; the whole work was achieved in his lifetime. Idolatry with its nameless abominations was entirely destroyed. The people who were sunk in superstition, cruelty, and vice in regions where spiritual life was utterly unknown were now united in one bond of faith, hope and charity. The tribes which had been from time immemorial engaged in perpetual wars were now united together by the ties of brotherhood, love, and harmony. Henceforth, their aims were not confined to this earth alone; but there was something beyond the grave - much higher, purer, and diviner - calling them to the practice of charity, goodness, justice, and universal love. They could now perceive that Allah was not that which they had carved out of wood or stone, but the Almighty Loving, Merciful, the Creator of the Universe.
