Ash Shaykh Muhammad Ibn Ali Ibn Hizaam said:

Imam Ash Shafiee in Ar Risaalah encouraged learning the Arabic language and mentioned some chapters in regards to that due to the importance of that as has preceded.

Due to that a person shouldn’t turn away from learning Nahwu (Arabic grammar) and he shouldn’t despair. The beginning of it becomes hard upon some people, then he becomes impatient with this field, and its not befitting that he become impatient rather upon him is that he has patience, and reads it time after time until Allah opens it upon him, perhaps it may become hard upon him in the beginning only, if he continues it will be made easy upon him by the permission of Allah, he shouldn’t make it much upon himself by studying more then a book, whilst the information repeats in every book.
