وَمِنَ ٱلْأَعْرَابِ مَن يَتَّخِذُ مَا يُنفِقُ مَغْرَمًا وَيَتَرَبَّصُ بِكُمُ ٱلدَّوَآئِرَ ۚ عَلَيْهِمْ دَآئِرَةُ ٱلسَّوْءِ ۗ وَٱللَّهُ سَمِيعٌ عَلِيمٌ

And of the dwellers of the desert are those who take what they spend to be a fine, and they wait (the befalling of) calamities to you; on them (will be) the evil calamity; and Allah is Hearing, Knowing.
