﴿ أَفَلَا يَتَدَبَّرُونَ ٱلْقُرْءَانَ أَمْ عَلَىٰ قُلُوبٍ أَقْفَالُهَآ ﴾

“Will they not, then, ponder over this Qur’an? - or are there locks upon their hearts?”

(Will they then not meditate on the Qur'an) regarding that which has been revealed about them, (or are there locks on the hearts) or are there locks on the hearts of the hypocrites such that they do not understand what is revealed about them?
