وَمِنَ الأَعرابِ مَن يَتَّخِذُ ما يُنفِقُ مَغرَمًا وَيَتَرَبَّصُ بِكُمُ الدَّوائِرَ ۚ عَلَيهِم دائِرَةُ السَّوءِ ۗ وَاللَّهُ سَميعٌ عَليمٌ

Among the Desert Arabs, some consider what they spend as a loss, and they await misfortunes to befall you. Yet, they will be afflicted by misfortunes. God is All-Hearing, All-Knowing.
