At-Tawba • EN-ASBAB-AL-NUZUL-BY-AL-WAHIDI
﴿ ٱلْأَعْرَابُ أَشَدُّ كُفْرًۭا وَنِفَاقًۭا وَأَجْدَرُ أَلَّا يَعْلَمُوا۟ حُدُودَ مَآ أَنزَلَ ٱللَّهُ عَلَىٰ رَسُولِهِۦ ۗ وَٱللَّهُ عَلِيمٌ حَكِيمٌۭ ﴾
“[The hypocrites among] the bedouin are more tenacious in [their] refusal to acknowledge the truth and in [their] hypocrisy [than are settled people], and more liable to ignore the ordinances which God has bestowed from on high upon His Apostle - but God is all-knowing, wise.”
(The wandering Arabs are more hard in disbelief and hypocrisy�) [9:97]. This verse was revealed about some Bedouins from the tribes of Asad and Ghatafan as well as about some other Bedouins who settled in Medina.
