Ningependa kutoa shukrani zangu kwa juhudi kubwa na msaada niliopokea katika kipindi chote cha kuandika, kuhariri na kuchapisha kitabu hiki. Shukrani nyingi zimwendee wahariri wataalamu wa muswada huu. Ninatoa shukrani zangu za dhati kwa maoni, mapendekezo na ushauri wa marafiki wengi, wenzangu na wanazuoni kutoka pembe mbalimbali za dunia, ambao walichangia kwa kiwango kikubwa utajiri wa taarifa zilizomo katika kitabu hiki.

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.

Ninatoa shukrani zangu za dhati kwa msaada endelevu na mkubwa wa Dkt. Mohammad Alweh, kwa mchango wake usio na kikomo na maoni yake. Binti yangu Fatima anastahili shukrani zangu za juu kabisa na upendo wangu kwa kubuni jalada la kitabu hiki.

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.

Ninatambua kwa dhati na kuthamini msaada na faraja ya kudumu niliyopokea kutoka kwa familia yangu, hasa mama yangu, ambaye anaendelea kunilisha kwa dua zake, ushauri wake na hekima yake. Ninathamini sana upendo mkubwa, msaada na uelewa wa mke wangu, binti yangu na wana wangu watano. Ndugu zangu saba wa kiume na dada zangu watatu wamenipa msaada wote na faraja. Ninadaiwa shukrani za pekee kwa kaka yangu Ahmad, ambaye alinihimiza kuandika kitabu hiki na kunipa ushauri na msaada wenye manufaa makubwa.

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.

Bila msaada na usaidizi kutoka kwa Mungu, nisingeweza kukamilisha kazi hii. Daima ninamkumbuka kwa shukrani kubwa kwa neema alizonijaalia.

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.
