Quran , ch 2 v 264

{O believers! Do not waste your charity with reminders ˹of your generosity˺ or hurtful words, like those who donate their wealth just to show off and do not believe in Allah or the Last Day. Their example is that of a hard barren rock covered with a thin layer of soil hit by a strong rain—leaving it just a bare stone. Such people are unable to preserve the reward of their charity. }
