All praise be to Allah, and may His blessings and peace be upon His messenger. This is a well written treatise on Sharia. It aims to explain it to the Muslim and non-Muslim public by linking many of its main teachings to their objectives, namely protecting the five essentials: faith, life, lineage, property, and intellect. The treatise candidly selected the more misunderstood teachings and ingenuously elucidated them. I hope this work will be of benefit for the Muslim and non-Muslim readership.
