وَمِنَ الْأَعْرَابِ مَن يَتَّخِذُ مَا يُنفِقُ مَغْرَمًا وَيَتَرَبَّصُ بِكُمُ الدَّوَائِرَ ۚ عَلَيْهِمْ دَائِرَةُ السَّوْءِ ۗ وَاللَّهُ سَمِيعٌ عَلِيمٌ ٩٨

And amongst these nomad villagers there is (also) one who regards that (money) which he spends (in the cause of Allah) as a compulsory fine, and looks forward to the spinning evil (of miseries and misfortunes) coming upon you. But it is they whom the evil spin (of calamity and ill-fortune) is going to whirl. And Allah is All-Hearing, All-Knowing. (9:98)
