Key Verses

1. 4:82An-NisaNarrative
   أَفَلَا يَتَدَبَّرُونَ ٱلۡقُرۡءَانَۚ وَلَوۡ كَانَ مِنۡ عِندِ غَيۡرِ ٱللَّهِ لَوَجَدُواْ فِيهِ ٱخۡتِلَٰفٗا كَثِيرٗا
   Will they not then ponder on the Qur'an? If it had been from other than Allah they would have found therein much incongruity.
   In context

   Why do these people not reflect over the Qur'ān and study it until they realise that it contains no differences or inconsistency, so that they can accept the truth of what you brought? Had it been from anyone other than Allah, they would have found inconsistencies in its rulings and differences in its meanings.

2. 47:24MuhammadNarrative
   أَفَلَا يَتَدَبَّرُونَ ٱلۡقُرۡءَانَ أَمۡ عَلَىٰ قُلُوبٍ أَقۡفَالُهَآ
   Will they then not meditate on the Qur'an, or are there locks on the hearts?
   In context

   Will these people who turn away not ponder over the Qur’ān and reflect over what is in it? If they pondered over it, it will guide them to every good and will distance them from every evil. Or are there locks on the hearts of these people that are tightly closed, so that no advice reaches them and no reminder benefits them?
