The author is a defender of the Imams of Guidance who carried on the Shari’a of the Master of Messengers (S), raised the saline features of the creed, explained the Sunnah and promoted righteousness. The said Imams (‘a) disseminated the Islamic teachings whenever they had the opportunity to do so, braving nUmarous trials and tribulations, persevering in every hostile environment. Their foes envied them while those who despised and hated them harboured a great deal of grudge against them. The intestines of some of them were cut open while the livers of others were chopped. Swords severed their joints, and they were hurled into dark dungeons. Despite all of this, the light of the truth did, indeed, dispel the darkness of misguidance. Truth always subdues falsehood. Generations have been obliterated and new ones have come as the scholars of the Infallible Household remain vigilant as guardians of theShari’a. They took upon themselves to study and clarify its obscurities and comprehend its pith The knowledge of Ahl alBayt (‘a) has received a great deal of attention and awarded a great deal of concern; therefore, major Islamic cities have been filled with many a genius and a scholar. These set up the rules and established the branches. Their pens delved into each and every field and wrote about every branch of knowledge and scholarship.
