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

And among the bedouins are some who consider what they spend as a loss and await for you turns of misfortune. Upon them will be a misfortune of evil. And Allah is Hearing and Knowing.
