The need for a key in urdu language to the book Dururs al-Lugath al-‘arabiyyah has long been felt. Such a key in urdu is now a reality Al-hamdulillah. Each lesson is dealt with in three sections. In the first section all the grammatical rules occuring in the lessons are explained. The second section gives a translation of the questions contained in the Exercise section. The third section contains the vocabulary. It is hoped that this key will greatly help those readers who wish to learn Arabic by themselves.
