﴿ وَمَآ أَنفَقْتُم مِّن نَّفَقَةٍ أَوْ نَذَرْتُم مِّن نَّذْرٍۢ فَإِنَّ ٱللَّهَ يَعْلَمُهُۥ ۗ وَمَا لِلظَّٰلِمِينَ مِنْ أَنصَارٍ ﴾

“For, whatever you may spend on others, or whatever you may vow [to spend], verily, God knows it; and those who do wrong [by withholding charity] shall have none to succour them.”

And whatever expenditure you expend, and whatever vow you make, surely God knows it, [knows] which type it is and rewards you accordingly. For the evildoers, those who expend to make a show before people, who expend in the wrong way, or who diminish what is their due by contemplating their expenditure or combining it with reminder [of one's favour] or injury, or by expending of what is vile: they have no helpers, to protect them from the might of God.
