This scholarly work by Dr. Faris Al-Sayyid Al-Sultani offers a deep linguistic investigation into the phenomenon of 'Al-Mu'arrab'—foreign words that have been assimilated into the Arabic language. The study meticulously analyzes the etymology and evolution of these loanwords throughout history. A significant portion of the book is dedicated to identifying and examining Arabized words found within the Holy Qur'an, providing critical insights for linguists, translators, and scholars of Quranic studies. It sheds light on the dynamic nature of the Arabic language and its interaction with other cultures and tongues.
