9:97
الأَعْرَابُ أَشَدُّ كُفْراً وَنِفَاقاً وَأَجْدَرُ أَلاَّ يَعْلَمُواْ حُدُودَ مَا أَنزَلَ اللّهُ عَلَى رَسُولِهِ وَاللّهُ عَلِيمٌ حَكِيمٌ
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.
9:101
وَمِمَّنْ حَوْلَكُم مِّنَ الأَعْرَابِ مُنَافِقُونَ وَمِنْ أَهْلِ الْمَدِينَةِ مَرَدُواْ عَلَى النِّفَاقِ لاَ تَعْلَمُهُمْ نَحْنُ نَعْلَمُهُمْ سَنُعَذِّبُهُم مَّرَّتَيْنِ ثُمَّ يُرَدُّونَ إِلَى عَذَابٍ عَظِيمٍ
Certain of the desert Arabs round about you are hypocrites, as well as (desert Arabs) among the Medina folk: they are obstinate in hypocrisy: thou knowest them not: We know them: twice shall We punish them: and in addition shall they be sent to a grievous penalty.
11:59
وَتِلْكَ عَادٌ جَحَدُواْ بِآيَاتِ رَبِّهِمْ وَعَصَوْاْ رُسُلَهُ وَاتَّبَعُواْ أَمْرَ كُلِّ جَبَّارٍ عَنِيدٍ
Such were the 'Ad People: they rejected the Signs of their Lord and Cherisher; disobeyed His messengers; And followed the command of every powerful, obstinate transgressor.
14:15
وَاسْتَفْتَحُواْ وَخَابَ كُلُّ جَبَّارٍ عَنِيدٍ
But they sought victory and decision (there and then), and frustration was the lot of every powerful obstinate transgressor.
50:24
أَلْقِيَا فِي جَهَنَّمَ كُلَّ كَفَّارٍ عَنِيدٍ
(The sentence will be:) "Throw, throw into Hell every contumacious Rejecter (of Allah)!-
74:16
كَلَّا إِنَّهُ كَانَ لِآيَاتِنَا عَنِيداً
By no means! For to Our Signs he has been refractory!
