Sura al-Tawbah 9:98

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

wa-mina l-aʿrābi man yattakhidhu mā yunfiqu maghraman wa-yatarabbaṣu bikumu l-dawāʾira ʿalayhim dāʾiratu l-sawʾi wallāhu samīʿun ʿalīmun

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).
