أَوَلَمْ يَعْلَمُوا أَنَّ اللَّهَ يَبْسُطُ الرِّزْقَ لِمَن يَشَاءُ وَيَقْدِرُ إِنَّ فِي ذَلِكَ لَآيَاتٍ لِّقَوْمٍ يُؤْمِنُونَ

Do they not know that Allah expands the provision for whomever He wishes and tightens it [for whomever He wishes]? There are indeed signs in that for a people who have faith.
