(Ankabooth ) 29 : 62
اللَّهُ يَبْسُطُ الرِّزْقَ لِمَنْ يَشَاءُ مِنْ عِبَادِهِ وَيَقْدِرُ لَهُ ۚ إِنَّ اللَّهَ بِكُلِّ شَيْءٍ عَلِيمٌ
Lord Allah extends provision for whom He wishes of His servants and restricts for whom He wishes; indeed Allah is the Knower of everything.
See explanation 16: 71 and 17: 30.
