Prophet Muhammad (sallallahu alaihi wa sallam) part 39 :

The continued part of invasion/successful conquest of Mecca :

The vast groups who had listened to the above declaration returned to their homes, and before the following year was over the majority of them were Muslims. During the tenth year of the hijrah, as in the preceding one, numerous embassies continued to pour into Medina from all parts of Arabia, to testify to the allegiance of their chiefs and their tribes.

Teachers were sent by the Prophet(ﷺ) into the different provinces to teach the new converts the principles and guidelines of Islam. These teachers were invariably given the following orders when they were about to depart on their mission: "Deal gently with the people, and be not harsh; cheer them, and do not look down upon them with disrespect. You will meet with many believers in the Holy Scriptures, who will ask you: 'What is the key to heaven?' Answer them it
(the key to heaven) is to bear witness to the divine truth and to do good."

Thus, the mission of the Prophet Muhammad(ﷺ) was now accomplished; the whole work was achieved in his lifetime. Idolatry with its nameless evils was entirely destroyed. The people who were sunk in superstition, cruelty, and immorality 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 everlasting 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.

In sha Allah, will be continued. {Ref : Stories of prophets by Ibn Kathir(rahimahullah)}
