Quran 4:38 — Women (Al-Nesa')

They give money to charity only to show off, while disbelieving in GOD and the Last Day. If one's companion is the devil, that is the worst companion.

[4:37] The ones who are stingy, exhort the people to be stingy, and conceal what GOD has bestowed upon them from His bounties. We have prepared for the disbelievers a shameful retribution.

[4:39] Why do they not believe in GOD and the Last Day, and give from GOD's provisions to them? GOD is fully aware of them.
