Moral qualities fall under two heads. First, those moral qualities that enable a person to discard evil; and, secondly, those moral qualities that enable him to do good. Discarding evil comprehends those qualities through which a person tries that he should do no harm to the property, honour or life of a fellow being by his tongue or his hand or his eyes or by any other organ, nor should he design to do him such harm. The doing of good comprehends all those moral qualities whereby a person tries to benefit a fellow being in respect of his property or honour by his tongue or his hand or his knowledge, or by any other means, or determines to make manifest his glory or honour, or overlooks a wrong that had been done to himself and thus benefits the perpetrator of the wrong by sparing him physical pain or financial imposition, or inflicts such chastisement upon him in respect of the wrong which is in reality a mercy for the wrongdoer.
