Surah At-Tawbah, ayah 98

وَمِنَ ٱلۡأَعۡرَابِ مَن يَتَّخِذُ مَا يُنفِقُ مَغۡرَمٗا وَيَتَرَبَّصُ بِكُمُ ٱلدَّوَآئِرَۚ عَلَيۡهِمۡ دَآئِرَةُ ٱلسَّوۡءِۗ وَٱللَّهُ سَمِيعٌ عَلِيمٞ ٩٨

Waminal-a'rābi man yattakhidhu mā yunfiqu maghraman wayatarabbasu bikumud-dawā'ira 'alayhim dā'iratus-saw'i wallāhu samī'un 'alīm

And among the bedouins are some who consider what they spend as a loss⁴⁹⁹ and await for you turns of misfortune. Upon them will be a misfortune of evil. And Allāh is Hearing and Knowing.
