﴿ 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.”
