O you who believe! do not make your charity worthless by reproach and injury, like him who spends his property to be seen of men and does not believe in Allah and the last day; so his parable is as the parable of a smooth rock with earth upon it, then a heavy rain falls upon it, so it leaves it bare; they shall not be able to gain anything of what they have earned; and Allah does not guide the unbelieving people.

Had We sent down this Quran on a mountain, you would certainly have seen it falling down, splitting asunder because of the fear of Allah, and We set forth these parables to men that they may reflect.
