     اِعْلَمْ أَنَّ مِمَّا أَضَرَّ بِٱلنَّاسِ فِي تَحْصِيلِ ٱلْعِلْمِ وَٱلْوُقُوفِ عَلَى غَايَاتِهِ كَثْرَةَ ٱلتَّآلِيفِ وَٱخْتِلَافَ ٱلِٱصْطِلَاحَاتِ فِي ٱلتَّعْلِيمِ وَتَعَدُّدَ طُرُقِهَا ثُمَّ مُطَالَبَةَ الْمُتَعَلِّمِ وَٱلتِّلْمِيذِ بِٱسْتِحْضَارِ ذٰلِكَ.

     It should be known that among the things that are harmful to the human quest for knowledge and to the attainment of a thorough scholarship are the great number of works (available), the large variety in technical terminology (needed for purposes) of instruction, and the numerous (different) methods (used in those works). The student is required to have a ready knowledge of (all) that.
