Reflection and Contemplation (Tadabbur)

أَفَلَا يَتَدَبَّرُونَ ٱلْقُرْءَانَ ۚ وَلَوْ كَانَ مِنْ عِندِ غَيْرِ ٱللَّهِ لَوَجَدُوا۟ فِيهِ ٱخْتِلَـٰفًا كَثِيرًا

Then do they not reflect upon the Qur’ān? If it had been from [any] other than Allāh, they would have found within it much contradiction.

فَٱنظُرْ كَيْفَ كَانَ عَـٰقِبَةُ ٱلْمُنذَرِينَ

Then look how was the end of those who were warned -

كِتَـٰبٌ أَنزَلْنَـٰهُ إِلَيْكَ مُبَـٰرَكٌ لِّيَدَّبَّرُوٓا۟ ءَايَـٰتِهِۦ وَلِيَتَذَكَّرَ أُو۟لُوا۟ ٱلْأَلْبَـٰبِ

[This is] a blessed Book which We have revealed to you, [O Muḥammad], that they might reflect upon its verses and that those of understanding would be reminded.
