O you who have believed, do not invalidate your charities with reminders [of it] or injury as does one who spends his wealth [only] to be seen by the people and does not believe in Allāh and the Last Day. His example is like that of a [large] smooth stone upon which is dust and is hit by a downpour that leaves it bare. They are unable [to keep] anything of what they have earned. And Allāh does not guide the disbelieving people.
O you who have faith in Allah and follow His Messenger, do not ruin the reward of your charity by boasting about it and hurting the person to whom you gave it. A person who does this is like one who spends to be seen and praised by people, and does not have faith in Allah and in the reward and punishment on the Day of Resurrection. This is like a smooth stone on which there is some dust: when heavy rain falls onto it, the dust is washed away and the stone is left smooth with nothing on it. Similarly, the reward of the actions and charity of those who show off does not remain in the sight of Allah. Allah does not guide disbelievers to what pleases Him and benefits them in their actions and spending.
