وَمِنَ الأَعْرَابِ مَن يَتَّخِذُ مَا يُنفِقُ مَغْرَمًا وَيَتَرَبَّصُ بِكُمُ الدَّوَائِرَ عَلَيْهِمْ دَآئِرَةُ السَّوْءِ وَاللّهُ سَمِيعٌ عَلِيمٌ
[9:98]
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.
Some of the desert Arabs look upon their payments as a fine, and watch for disasters for you: on them be the disaster of evil: for Allah is He That heareth and knoweth (all things).
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.
