How should we call potential reverts) to Islam?

Question

Calling others to Islam is an honorable mission. The Muslims in general and the Scholars in particular are commanded to call people to Islam. The caller may be faced with debates. Allah Ta’ala has commanded us that, if it reaches the point of debate, to debate in a manner that is better, that is with kindness and gentleness, explaining the principles of Islam as they came, pure and simple with no compulsion.
