ٱلۡأَعۡرَابُ أَشَدُّ كُفۡرٗا وَنِفَاقٗا وَأَجۡدَرُ أَلَّا يَعۡلَمُواْ حُدُودَ مَآ أَنزَلَ ٱللَّهُ عَلَىٰ رَسُولِهِۦۗ وَٱللَّهُ عَلِيمٌ حَكِيمٞ

Al A'raabu ashaddu kufranw wa nifaaqanw wa ajdaru allaa ya'lamoo hudooda maaa anzalal laahu 'alaa Rasoolih; wallaahu 'Aleemun Hakeem

The Arabs of the desert are the worst in Unbelief and hypocrisy, and most fitted to be in ignorance of the command which Allah hath sent down to His Messenger: But Allah is All-knowing, All-Wise.
