وَلَقَدۡ صَرَّفۡنَا لِلنَّاسِ فِي هَٰذَا ٱلۡقُرۡءَانِ مِن كُلِّ مَثَلٖ فَأَبَىٰٓ أَكۡثَرُ ٱلنَّاسِ إِلَّا كُفُورٗا ٨٩
English — A. Maududi (English Tafhim commentary)
We have explained things for people in this Qur'an in diverse ways to make them understand the Message, yet most people obstinately persist in unbelief.
Urdu — Tafheem-ul-Quran, Syed Abul A'la Maududi
