After that...
After that, it was due to this blessing bestowed by the Imam (a) that Hisham was always victorious like a champion over his enemies in discourses. He used to say always that he achieved this power in himself and felt a holy light due to the blessing of Imam (a).
"By God, till this day when I am standing here, nobody has defeated me in religious discourses." Witticism of Hisham The respected scholar Sayyid Mohsen Jabal Amili (God bless him) writes in his valuable book A'yan al Shi'a that too many eulogies have been quoted by the two Imams (the 6th Imam Ja'far ibn Muhammad and the 7th Imam (a) about Hisham.
Then he adds: It is enough to say regarding Hisham's readiness to answer and his impromptu speeches, that one day people asked him whether Mu'awiyah was present in the Battle of Badr or not? He replied quickly: Yes, but on the other side. That is, he was present but was among the opponents and a member of the enemy's army.
Books of Hisham Hisham is the first man who discussed and deliberated the fundamentals of beliefs and topic of leadership in the Islamic world on the basis of the scientific point of view. He wrote books on those topics and opened the way for research and debate for the coming generations. By using rational and traditional reasoning in his speeches and writings, he made the sublime goal and the benefit of the Shi'a school clear for the other Muslims and foreign scholars.
Hisham had many books on different scientific fields but unfortunately, today there is nothing left except their names written in the books. Ibn Nadeem and a group of other great writers have counted his books to be about thirty volumes. Allamah Helli writes: Hisham has compiled a book against dualists and separatists and another book against "Aristotle", "Shaikh and the Slave" and "Eight Chapters" were among his books.
The Founder of the Science of the Fundamentals of Religion The late Allamah Sayyid Mohsen Amili, the writer of A'yan al Shi'a says: Hisham has written the book- Al-Alfaz. So the statement of Jalaluddin Seuti: that the first writer of the fundamentals of Muslim laws, according to the consensus of scholars, is Shafei, "is not correct, because Hisham b. Hakam has been living a very long time before him.
Moreover to emphasize this point it is known that Imam al-Baqer (a) and Imam al-Sadiq (a) used to teach the complete and useful rules of this science from the chapters of etymological arguments and rational proofs to their pupils and followers.
