Surah Saba, Verse 39

قُلۡ إِنَّ رَبِّي يَبۡسُطُ ٱلرِّزۡقَ لِمَن يَشَآءُ مِنۡ عِبَادِهِۦ وَيَقۡدِرُ لَهُۥۚ وَمَآ أَنفَقۡتُم مِّن شَيۡءٖ فَهُوَ يُخۡلِفُهُۥۖ وَهُوَ خَيۡرُ ٱلرَّٰزِقِينَ٣٩

qul inna rabbī yabsuṭu l-riz'qa liman yashāu min ʿibādihi wayaqdiru lahu wamā anfaqtum min shayin fahuwa yukh'lifuhu wahuwa khayru l-rāziqīna

Say, "Indeed, my Lord extends provision for whom He wills of His servants and restricts [it] for him. But whatever thing you spend [in His cause] - He will compensate it; and He is the best of providers."
