﴿إِنَّآ أَنْزَلْنَاهُ قُرْآنًا عَرَبِيًّا لَّعَلَّكُمْ تَعْقِلُونَ ﴾
“Verily, We have sent it down as an ‘Arabic Qur’aan in order that you may understand.”
Soorah Yoosuf 12:2
The ‘Arabic language is the most eloquent, plain, deep and expressive of the meanings that might arise in one’s mind. Therefore, the most honorable Book, was revealed in the most honorable language, to the most honorable Prophet and Messenger (sallallaahu ‘alaihi wa sallam), delivered by the most honorable Angel (‘alaihis salaam), in the most honorable land on earth, and its revelation started during the most honorable month of the year, Ramadhaan. Therefore, the Qur’aan is perfect in every respect.
