The trials of scientists in Egypt in the Mamluk era Taqi al-Din ibn al-'Aziz (d. 695 AH / 1295 AD) is a model

   The chief magistrates Taqi AL-Deen Abu-AL-Qasim Abdu-AL-Rahman bin Abdu-AL-Wahab bin khalaf AL-Alami AL-Masry AL-Shafi’i، one of the those who left a relevant print in the political، social and intellectual Egyptian history in the early first Mamluk age، according to the important administrational posts he occupied ;last of them was the chief magistrates of the Egyptian country. Where no character before him or of his contemporaries known had gathered seventeen administrational and scientific posts at the same time and ran them all soundly and professionally witnessed by all. Let alone his scientific status that enabled him to teach in the most important schools in Egypt and Cairo at that time. So، it is not strange to be the profession that he occupied under the minister bin AL-Saalous، an important event dealt with it the pens of his contemporaries of historians or whom came latter; which shade lights on the hidden causes laid behind that profession.
   from other side، the event that the magistrate AL-Taqi exposed without any doubt the amount of the hidden conflict between the minister bin AL-Saalous who was supported by AL-Sultan AL-Ashraf Khaleel of one side and the mamluk  princes of the other side about gaining the utmost authority and privileges، that conflict which emerged after a short time to public to reveal bad conclusions laid their effect in addition to other factors – in a disastrous end to those countries where the sultan and his minister met their end in a terrified way.
   what rises the importance of that event، entering a wide spectrum of scientists and Islamic jurists on the lines of events to refer to us the amount of conflict which was standing amongst them for the sake of gaining the privileges and administrational posts.
