Surah 92. Al-Lail, Ayah 20

The definition of Righteousness, Charity, or Self-sacrifice, becomes thus highly spiritualised. The Atqa are so completely identified with Allah's Will that everything else is blotted out to them. What would seem to be sacrifice from other points of view, becomes their own highest pleasure and satisfaction. Every virtuous man will have his own bliss, for there are degrees in virtue and bliss. This supreme bliss is the portion-not the prize-of supreme virtue.
