I used to discuss many secular persons about Islam. They had some questions and objectios. I am trying here to answer some of their questions.
Atheist: Islam has spread by the sword.
Muslim: This is not true. Islam has spread in many countries in Asia and Africa without any military action. The Islamic civilization is a fact that cannot be denied. Ask Europe about the Islamic civilization in Spain and the darkness of Europe. Islam is not a barbaric religion. But Islam is the true religion. The Islamic civilization used the military actions for defence and for attacking some enemies. But the muslims did not enforce anyone to convert to Islam. The muslims treated non-muslims justly. They wanted to convince them not to enforce them to convert to Islam.
Atheist: I do not need any religion.
Muslim: Who has created the universe? Who has created you? What is the aim of your life? What will happen to you after death? All these are questions that you cannot find answers to without Islam. Besides, you enjoy materialistic pleasures, but you neglect your soul. Islam achieves the balance and harmony between the soul and the body. Islam does not forbid materialistic pleasures, but Islam is a unit of enjoying our lives and more important obeying our God and Creator.
Atheist: There is no soul.
Muslim: You deny the presence of the soul because you cannot see and cannot touch the soul. We cannot see electricity, but we are sure that there is some thing called electricity because we can see its effects -the light and the heat for example-. Equally, we cannot see the soul, but we can see its effects. What is the difference between two young men: one of them can talk and move while the other is dead without any reason? He did not suffer from any disease. He was not the victim of any accident. The difference is that the soul of the first one is inside his body while the soul of the second one had left his body.
Atheist: What is the difference between Islam and Christianity?
Muslim: The true Christianity invited people to worship One Deity, but some of its followers changed it. The unchanged Bible said that there will be a prophet called Muhammad or Ahmed and invited christians to follow him. The untrue christianity says that there is a God and his son. This is untrue. If the God decided something and his son decided another thing, what will happen? There will be a conflict between the God and his son. In Islam, there is only One God and He has no sons.
Atheist: There is no God.
Muslim: The universe is changable, so it cannot be eternal. The God created the universe. The God is eternal. I invite you to rethink about the presence of the God and to read the Holy Quran. I invite you to read about Islam from the Islamic point of view.
