At Tawbah, 97 Ayah
9:97
ٱلۡأَعۡرَابُ أَشَدُّ كُفۡرٗا وَنِفَاقٗا وَأَجۡدَرُ أَلَّا يَعۡلَمُواْ حُدُودَ مَآ أَنزَلَ ٱللَّهُ عَلَىٰ رَسُولِهِۦۗ وَٱللَّهُ عَلِيمٌ حَكِيمٞ ٩٧
Al-'A`rābu 'Ashaddu Kufrāan Wa Nifāqāan Wa 'Ajdaru 'Allā Ya`lamū Ĥudūda Mā 'Anzala Al-Lahu `Alá Rasūlihi Wa ۗ Allāhu `Alīmun Ĥakīmun
The bedouins are stronger in disbelief and hypocrisy and more likely not to know the limits of what [laws] Allah has revealed to His Messenger. And Allah is Knowing and Wise.
