Synopsis This treatise aims at introducing the founder-jurisconsults of Islamic Law the four Great Imams; namely, Imam Abu Hanifah, Imam Malik, Imam al-Shafi'i and Imam Ahmad bin Hanbal may Allah have mercy on them all.  The altruistic believers should have collaborated in achieving coherence, cohesion and consolidation in the Ummah and thereby proved their loyalty to the universal Message of Muhammad, ‘alaihissalam, for the reason that it ensured salvation not only to Muslims but also to the rest of Humanity. The Imams and their true Pupils never wanted to create conflict or strife among the votaries of Islam. They issued verdicts, opinions and Fatwas on Furu (Branches) of Sharia. To achieve solidarity against the assaults of corruption and evil, a dispassionate study of the personal merits of each Imam is a must today.
