Undoubtedly this book would not have been possible without God. I praise and thank Him. Once you finish reading this book you will realise that everything depends on God and He alone is worthy of perfect praise and gratitude.

The Prophet Muhammad صلى الله عليه وسلم taught that the person who has not thanked people has “not thanked God.”1

In this light, there are a number of people to whom I owe thanks for helping and encouraging me to write this book.

First among them are my family. I cannot ever forget the love, patience, support, encouragement and sacrifices of my wife and children. My neglect and isolation was endured and overlooked by the people I love. The fact that God gave me such a family is something that deserves eternal gratitude. I would like to show my appreciation to my brother Spyros Tzortzis. He was an early intellectual inspiration in my life. We shared the same bedroom for over two decades. His ability to think outside of the box and explore new ideas planted intellectual ‘seeds’ in my mind, the fruit of which is this book. I would like to thank my sister Haris Tzortzis. She has always supported me and never defined me by my faults, always by my strengths. My mother Androula Tzortzis is one of the most loving people that I know. Her undying love, energy and support have shaped who I am. My father Petros Tzortzis has always been my hero. His patience, tolerance, love, humility and wisdom have inspired me. I can never repay my parents. Anything I say cannot truly express the gratitude that is due to them. I pray that God guides and protects my family, and that He grants them long, healthy lives full of joy, love and piety. I pray that He continues to unite us in love. I want to thank my friend Imran Hussein. Imran reviewed the book and provided significant input. His contribution to Chapter 3 was extensive. I am also extremely grateful to my friend Subboor Ahmad, who provided important contributions and moral support.

I want to express my deepest gratitude to Abu Hurayra. He is one of the smartest people I have had contact with. Although we have never met, due to our similar interests we have exchanged ideas. He reviewed the book at its early stage and his input was beyond significant. Without his incisive criticism and contribution this book would not have been possible.

I would like to thank the author and academic Dr. Safaruk Chowdhury. Our friendship has inspired me to pursue further studies in Islamic thought and philosophy. His review of the book and scholarly contribution was extremely helpful.

I would like to thank Asif Uddin, who spent hours researching various Islamic classical texts. His input and corrections helped shaped the character of the book. I am ever grateful to my friend Adnan Rashid. His review of the book and his contribution to Chapter 14 was extensive.

I would also like to express my gratitude to Dr. Atif Imtiaz and Sharif Randhawa for their important suggestions and advice.

I would like to thank Umm-Talha bint Abi-Bilal who did a last minute review of the entire manuscript. I am grateful to Ghazi Mannai, Fahad Tasleem, Dr. Mohamed Ghilan, Anthony Green, Salahuddin Patel, Joni Molla, Esa Khan, Abdullah Mekki, Moseen Khalid, Zeenat Bibi, Abu Zakariya and Umm Zakariya for their noteworthy support and contributions. Finally, I would like to thank John Paine for his editorial work and iERA and Sapience Institute for their support which helped make this book become a reality. There are many more people whom I should show my appreciation and gratitude to. However, anyone that has been left out, know that your reward is with God, and what is from Him cannot be compared to anything in this world.
