Abu Taleb Muhammad, known as: Fakhr al-Muhaqeqin (Honour of scholars) Fakhr al-Islam and Fakhr al-Din, great scholar (1282 – 1311) in Hilla – Iraq. He was son of “Allameh Helli” (prominent scholar). He studied primary and common sciences of his own time in the presence of his father. He also studied philosophy, theology, logic, Hadith, intellectual & transmitted sciences and jurisprudence (Fiqh) & methodology (Osul); Helli studied all the sciences under his father and did not have any other masters. He became an expert scholar at intellectual and #### transmitted sciences, therefore when he finished his education, asked his father to write a comprehensive book on jurisprudence. Some scholars such as: “Noor Allah Shushtari” and “Fazel Hendi” believe that Fakhr al-Muhaqeqin at the time of writing the book was 10 years old or less and was a great “Mujtahed” (a person who possesses the aptitude to form his own judgement on questions concerning Islamic law), but this idea is wrong because as “Allameh Helli” (b. 1249) wrote in the book: “My son! I summarised the rules and commandments of Islam and explained them in an easy way, I am now 50 years old”. Therefore the book was written in 1299 and Fakhr al-Muhaqeqin was 16. Allameh Helli loved his son; he wrote the book “al Alfin” (Thousands) by request of Fakhr al-Din. The book is on thousands intellectual and transmitted reasons on proving Imamte of Imam Ali (p.b.u.h) and thousands reasons on rejecting doubts of opponents and also many reasons on proving Imamate of other Imams.
