9:98
وَمِنَ ٱلْأَعْرَابِ مَن يَتَّخِذُ مَا يُنفِقُ مَغْرَمًا وَيَتَرَبَّصُ بِكُمُ ٱلدَّوَآئِرَ ۚ عَلَيْهِمْ دَآئِرَةُ ٱلسَّوْءِ ۗ وَٱللَّهُ سَمِيعٌ عَلِيمٌ
wamina l-aʿrābi man yattakhidhu mā yunfiqu maghraman wayatarabbaṣu bikumu l-dawāira ʿalayhim dāiratu l-sawi wal-lahu samīʿun ʿalīmun
Some of the desert Arabs consider what they give to be an imposition; they are waiting for fortune to turn against you, but fortune will turn against them. God is all hearing and all knowing.
And of the bedouins there are some who look upon what they spend (in Allâh’s Cause) as a fine and watch for calamities for you, on them be the calamity of evil. And Allâh is All-Hearer, All-Knower.
