All praises belong to Allah, as numerous as the number of His creation, abundant to His desire, equal to the weight of His Throne, and as plentiful as the amount of His words. To Him belongs praise appropriate to His Perfect Countenance and Magnificent Dominion. I praise Him for His immense bounties and enormous favours. Every bounty and favour we enjoy is from Allah subhanahu wa ta ‘ala alone. Whoever endeavours to count the favours of Allah will never be able to enumerate them.
I am dutifully grateful and thankful to Allah subhanahu wa ta ‘ala for facilitating the writing of this treatise for me and for His continuous assistance till its completion. Praise belongs to Him at the beginning and at the end for empowering me and guiding me. I beg Him subhanahu wa ta ‘ala for an increase in His grace and generosity and to accept this humble action for His pleasure.
Adhering to Prophetic practice and the conduct of the Messenger salla Llahu ‘alayhi wa sallam:
لا يشكر الله من لا يشكر الناس
He has not been grateful to Allah who has not expressed appreciation to people.
Firstly, I express my heartfelt appreciation to my benevolent parents who, after Allah subhanahu wa ta ‘ala, played the most prominent part in my seeking, acquisition, and dedication to knowledge. Allah subhanahu wa ta ‘ala alone do I invoke to protect them, nurture them, and make them the coolness of my eyes in the world and the Hereafter. He is the patron of this and All-Powerful to make it a reality.
Secondly, I express gratitude to Markaz al Buhuth wa al Dirasat at Mabarrat al Al wa al Ashab for their participation in preparing this book, from proposing the idea, supervision of the project, sourcing and referencing, emendation of few discussions, to communication of valuable considerations until the book reached completion. Appreciation is expressed to al Mabarrah Institute for their interest in the book and administering its printing and publishing.
At the same time, I am thankful to every person who taught me, guided me, or apprised me of a mistake.
Finally, this is the effort of one lacking proficiency. Everything correct is from Allah subhanahu wa ta ‘ala and any error is from me and Shaitan. Allah subhanahu wa ta ‘ala has reserved perfection for His mighty Book. Allah subhanahu wa ta ‘ala announces:
إِنَّ الَّذِيْنَ كَفَرُوْا بِالذِّكْرِ لَمَّا جَاءَهُمْ وَإِنَّهُ لَكِتَابٌ عَزِيْزٌ لَّا يَأْتِيْهِ الْبَاطِلُ مِنْ بَيْنِ يَدَيْهِ وَلَا مِنْ خَلْفِهِ تَنزِيْلٌ مِّنْ حَكِيْمٍ حَمِيْدٍ
Indeed, those who disbelieve in the message after it has come to them… And indeed, it is a Mighty Book. Falsehood cannot approach it from before it or from behind it; [it is] a revelation from a [Lord who is] Wise and Praiseworthy.
