Quran 34:39

قُلۡ إِنَّ رَبِّى يَبۡسُطُ ٱلرِّزۡقَ لِمَن يَشَآءُ مِنۡ عِبَادِهِۦ وَيَقۡدِرُ لَهُ ۥۚ وَمَآ أَنفَقۡتُم مِّن شَىۡءٍ۬ فَهُوَ يُخۡلِفُهُۖ ۥ وَهُوَ خَيۡرُ ٱلرَّٲزِقِينَ ٣٩

Say, "My Lord is the One who controls all provisions; He increases the provisions for whomever He chooses from among His servants, or reduces them. Anything you spend (in the cause of ALLAH), He will reward you for it; He is the Best Provider."
