قُل إِنَّ رَبّي يَبسُطُ الرِّزقَ لِمَن يَشاءُ مِن عِبادِهِ وَيَقدِرُ لَهُ ۚ وَما أَنفَقتُم مِن شَيءٍ فَهُوَ يُخلِفُهُ ۖ وَهُوَ خَيرُ الرّازِقينَ

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."
