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

Among the Bedouins are those who regard what they spend as a loss, and they watch for a reversal of your fortunes. Theirs shall be an adverse turn of fortune, and Allah is all-hearing, all-knowing.
