ACKNOWLEDGMENT

All Praise and thanks be to Allah. We praise and thank him, ask Him for his help and forgiveness, and we seek refuge in Allah from the evils of our souls and the mischief’s of our deeds. He whom Allah guides will not be misled, and he whom Allah misleads will never have a guide. I testify that there is no deity but Allah alone, without any partners, and that Muhammad is his 'Abd (worshiper) and Messenger Sallallahu 'Alaihi wa Sallam.

I dedicate this report to my parents who gave me all the support. My prayers for forgiveness, mercy for them and to reach their soul. Also to my brothers and sisters for their support as well as my best friend Muhammed Bubshait and my two daughters.
