Quran 28:67

, he that is bereft of Faith, is unfit to make offerings to the deities. The food of only such a man is unfit to be eaten. This is the opinion of men conversant with duties. Want of Faith is a high sin. Faith is a cleanser of sins. Like a snake casting off its slough, the man of Faith succeeds in casting off all his sin. The religion of abstention with Faith is superior to all things considered sacred. Abstaining from all faults of behaviour, he who betakes himself to Faith, becomes sanctified. What need hath such a person of penances, or of conduct, or of endurance? Every man has Faith. Faith, however, is of three kinds, viz., as affected by Sattwa, by Rajas and by Tamas, and according to the kind of Faith that one has, one is named. Persons endued with goodness and possessed of insight into the true import of morality have thus laid down the subject of duties. We have, as the result of our enquiries, got all this from the sage Dharmadarsana. O thou of great wisdom, betake thyself to Faith, for thou shalt then obtain that which is superior. He who has Faith (in the declarations of the Srutis), and who acts according to their import (in the belief that they are good for him), is certainly of righteous soul. O Jajali, he who adheres to his own path (under the influence of Faith) is certainly a superior person.'"

For what if some did not believe? shall their unbelief make the faith of God without effect?

2 Bless thou the man who gives, O Faith; Faith, bless the man who fain would give. 3 Even as the Deities maintained Faith in the mighty Asuras, So make this uttered wish of mine tr

Such threefold faith, in highest piety Kept, with no hope of gain, by hearts devote, Is perfect work of Sattwan, true belief.
