[2:262] Those who spend their money in the cause of GOD, then do not follow their charity with insult or harm, will receive their recompense from their Lord; they have nothing to fear, nor will they grieve.
[2:263] Kind words and compassion are better than a charity that is followed by insult. GOD is Rich, Clement.
[2:264] O you who believe, do not nullify your charities by inflicting reproach and insult, like one who spends his money to show off, while disbelieving in GOD and the Last Day. His example is like a rock covered with a thin layer of soil; as soon as heavy rain falls, it washes off the soil, leaving it a useless rock. They gain nothing from their efforts. GOD does not guide disbelieving people.
