The book "Existence of God and Tawheed" deals with a complex subject. This book is considered the best book of Dr. Malik Ghulam Murtaza (martyr). In this book, the existence of Allah Ta'ala has been proved by three types of arguments. The first type of arguments are natural arguments, which by hearing or reading, the human nature testifies to the existence of Allah Almighty. The second type of argument is rational, which is related to reason, mind and consciousness. By reading these arguments, a person consciously becomes convinced of the existence of Allah. The third type of argument is Sharia. In these arguments, arguments have been given for the existence of Allah Ta'ala with the help of Quran and Sunnah. Alhamdulillah, by reading this book, thousands of disbelievers repented and believed in the existence of Allah. (Professor Dr. Hafiz Muhammad Zaid Malik).
