This booklet presents a suppositional dialogue between a Muslim and a pagan. It starts with a question from the Muslim to the pagan whether he believes in any deity besides God. The pagan said: Yes. Then the Muslim nullified the godship and lordship of all deities besides the True God the Almighty using logical and religious evidences from the Holy Qur'an. After a long dialogue the Muslim convinced the pagan that God is One Who has the right to be worshipped, and Who Has the creation, command and kingdom. And deities have nothing to do and they do not cause harm or bring any benefit. At the end the pagan was convinced and he embraced Islam. Praise be to Allah by His grace good deeds are fulfilled.
