وَمِنَ ٱلْأَعْرَابِ مَن يَتَّخِذُ مَا يُنفِقُ مَغْرَمًا وَيَتَرَبَّصُ بِكُمُ ٱلدَّوَآئِرَۚ عَلَيْهِمْ دَآئِرَةُ ٱلسَّوْءِۗ وَٱللَّهُ سَمِيعٌ عَلِيمٌ ٩٨
And of the wandering Arabs there is he who taketh that which he expendeth (for the cause of Allah) as a loss, and awaiteth (evil) turns of fortune for you (that he may be rid of it). The evil turn of fortune will be theirs. Allah is Hearer, Knower.
