The National Library of Paris maintains a handwritten collection of seven letters, mentioned by the orientalist Baron de Slane in the index he created for the manuscripts of the aforementioned library. the group .
I asked the handwritten group to be photographed in a microphone and a film, and I started to read what I care about from it, and I was amazed when I read the page numbered (1112) after the Basmalah: (Sheikh Badr al-Din bin Umm Qasim, may God Almighty have mercy on him, said: I asked, may God grant you success, about the one that has a place of Arabic, because The campaign has its origins ... and this topic continues until the end of the paper (161).
I was pleased with what I read, because a new trace I found of Al-Muradi was among the missing, as no one mentioned that Al-Muradi was classified with this title. Even the orientalist de Slane, when he described the groups messages, was blinded by the message of al-Muradi, and he thought it a continuation of the book (The Thirty Rules), and this matter was also permissible for Professor Saeed al-Afghani when he described the group in his introduction to the book The Strangers in the Controversy of the Arabs by Abu al-Barakat Ibn al-Anbari. One of the compilations included in the Khattiyyah collection, he considered the letter of al-Mouradi a safe part (grammar) of al-Qurafi.
And since I had studied al-Mouradi and his life, learned about his method of research, and traced all his effects and tested him in books of grammar, classes and manuscript indexes, I preferred to achieve this valuable effect, and correct his attribution to (Ibn Umm Qasim), and here I am presenting in my hands the investigation with a brief study For the message and its author.
