In the Name of Allah, the Merciful, the Compassionate

The Prophet of Islam, peace be upon him and his pure family, remained in the city of Mecca for approximately thirteen years when he was sent as a messenger. He then migrated to the city of Medina and remained there until his death on the 28^th of Safar [1] .
During the thirteen years that the Prophet remained in Mecca, historians report that the number of converts to Islam was less than two hundred.

And you see people entering the religion of Allah in troops [2]

During the short period that the Prophet was in Medina, hundreds of thousands of people converted to Islam, most of which occurred during the last two or three years of the holy Prophet's life. How, one might ask, did the Prophet achieve such a goal?

The Prophet Mohammad is the greatest and most honourable person that Allah has ever created. Imam Ali was once asked if he was superior to Prophet Mohammad. Imam Ali replied, "I am but one of the servants of Mohammad"[3].  Moreover, the quality of the traditions, laws, and the system that Prophet Mohammad chose for Muslims are in line and consistent with his character and merits. There is a direct relationship between his personal, intellectual, and spiritual qualities and those of the laws he brings.  Just as the Prophet is the best of creation, his laws too are the best and most perfect of laws and regulations.

Throughout his stay in Mecca since the start of his Prophetic mission, the Prophet's plans and policies did not materialize; his teachings were not implemented or practiced as the right environment was not yet available for them to be implemented, nor did he have the necessary means to do so, such that it would become known how he would deal with people:

• How will he deal with his supporters and opponents?
• What is his monetary policy?
• What are his policies for a war and its aftermath?
• What type of government would he create?
• What is his personal lifestyle and practice?

All of these questions were addressed [when the Prophet established his base] in Medina.  Almost twenty-five years after the death of the Prophet, when Imam Ali assumed the office of government, he revived and implemented the same policies and principles that the Prophet had, during his reign of less than five years.

The life of Prophet Mohammad contains great many examples of his conducts and policies that if they were collected and presented to humanity, many people would be so impressed by them that they would ultimately adopt Islam as a way of life.  If we truly follow the genuine laws and traditions of the Holy Prophet and Imam Ali in every aspect of our lives, then what occurred fourteen centuries would happen again, which is what Allah states in the abovementioned verse in the Holy Qur'an. Then you would see millions of non-Muslims would willingly join Islam.
