ٱلْأَعْرَابُ أَشَدُّ كُفْرًا وَنِفَاقًا وَأَجْدَرُ أَلَّا يَعْلَمُوا۟ حُدُودَ مَآ أَنزَلَ ٱللَّهُ عَلَىٰ رَسُولِهِۦ ۗ وَٱللَّهُ عَلِيمٌ حَكِيمٌ
Al A'raabu ashaddu kufranw wa nifaaqanw wa ajdaru allaa ya'lamoo hudooda maaa anzalal laahu 'alaa Rasoolih; wallaahu 'Aleemun Hakeem
The desert Arabs are harder in denial and hypocrisy, and more likely to be ignorant of the limits of what God has sent down to his Messenger. And God is all-knowing, all-wise.
