It is no secret to anyone that studying and investigating books of jurisprudence, despite their suffering, is a pleasure that cannot be compared to pleasure, and it has benefits and importance that cannot be limited and summed up, and it has great fruits that researchers and students of knowledge reap, as well as enriching libraries with jurisprudential material, after dusting them and taking them out to the light of libraries to be seen. Researchers and scholars, generation after generation, so that this nation can benefit from this pioneering intellectual and scientific product that was written for us by our first ancestors of working scholars who enriched human civilization with this scientific material, which has become a beacon guiding the people of the earth and its countries. In the titles of the manuscripts in the libraries to choose a manuscript for investigation and study, my view fell on the title of this manuscript and marked (Al-Azhar’s saying in the fatwa with it from the sayings of Imam Zafar) by Imam Piri Zadeh, d. 1099 AH.. which will enrich the Arab Islamic library.
