This book has two parts. The first part: "Can God Create a Rock He Cannot Lift?" is about how we can fight with doubts that come to mind about Allah and gives persuasive answers based on the concept of the deity in Islam. Could there be something that God's power is not enough for? Can God kill himself? Who created God? " And so on... Can such questions bring a deficiency to God's glory? Believing in God is the first of the six pillars of faith. But it is not enough just to accept that God exists. If we do not have a correct belief in Allah, our faith is ready to be shaken and leave us at any moment. This work is like a ready-made template. It can answer many questions about Allah... The second part: Is the Quran the Word of God? The Qur'an is God's word, but it was revealed to us in our language. Shouldn't it have come down even more miraculously since Allah spoke? Why does the Quran only mention Arabian Peninsula fruits and not pineapples? In this work, I have provided succinct but convincing responses to these questions. If you come across similar questions, you'll be able to answer them using the same logic.
