Аль-Мутаффифин 83:4

Every human being wants to have his dues paid in full. But it is only right and proper that, if he is a man of character, he should also take care to give to others their full and rightful dues. He should want for others whatever he wants for himself. Those who take full measure for themselves and give less to others, will reach the Hereafter in such an ill state of grace that they will be doomed to eternal perdition. One who tries to ensure full measure for himself knows that everyone should receive his just deserts. In this context, if he gives less while giving to others, he lessens his realization of or sensitivity to the rights of others. If a man repeats this sort of misdeed again and again, a time will finally come when he will completely lose his sensitivity to others’ rights. His heart will be completely corroded by his sinful actions. In the present world many people are not at all keen to respect the rights of others or to give them their full dues. They are interested solely in recovering in full what is due to them from others. Such people will remain in a state of deprivation in the Hereafter. Wise are those who are eager to discharge others’ rights and dues fully, because they are the ones who will be entitled to the great bounties of God in the Hereafter.
