2:270
وَمَآ أَنفَقْتُم مِّن نَّفَقَةٍ أَوْ نَذَرْتُم مِّن نَّذْرٍ فَإِنَّ ٱللَّهَ يَعْلَمُهُۥ ۗ وَمَا لِلظَّـٰلِمِينَ مِنْ أَنصَارٍ
wamā anfaqtum min nafaqatin aw nadhartum min nadhrin fa-inna l-laha yaʿlamuhu wamā lilẓẓālimīna min anṣārin
Whatever you may give, or vow to give, God knows it well, and those who do wrong will have no one to help them.
And whatever you spend for spendings (e.g., in Sadaqah - charity for Allâh’s Cause) or whatever vow you make, be sure Allâh knows it all. And for the Zâlimûn (wrong-doers) there are no helpers.
