I would like to acknowledge the great effort and support I received throughout the period of writing, editing, and publishing of this book. Many thanks are due to the professional editors of this manuscript. I sincerely acknowledge the comments, suggestions, and feedback of scores of friends, colleagues and scholars around the world who provided invaluable contribution to the wealth of information provided in this book.

I humbly acknowledge the continued and significant support of Dr. Mohammad Alweh for his endless contribution and feedback. My daughter Fatima deserves my best appreciation and love for designing the cover of the book.

I certainly acknowledge and appreciate the enduring support and encouragement I received from my family, especially my mother, who continues to nourish me with her prayers, advices and wisdom. I certainly appreciate the great love, support, and understanding of my wife, my daughter and five sons. My seven brothers and three sisters have provided me with all the support and encouragement. I am especially indebted to my brother Ahmad who encouraged me to write this book and provided most helpful advices and support.

Without the support and help from God, I could not have accomplished this task. I am always in deep remembrance to the bounties he bestowed upon me.
