Appears 10 times in the Quran. (Root: نفق)
  1. (As for) those who spend their property in the way of Allah, then do not follow up what they have spent with reproach or injury, they shall have their reward from their Lord, and they shall have no fear nor shall they grieve.

  2. Men are the maintainers of women because Allah has made some of them to excel others and because they spend out of their property; the good women are therefore obedient, guarding the unseen as Allah has guarded; and (as to) those on whose part you fear desertion, admonish them, and leave them alone in the sleeping-places and beat them; then if they obey you, do not seek a way against them; surely Allah is High, Great.

  3. And what (harm) would it have done them if they had believed in Allah and the last day and spent (benevolently) of what Allah had given them? And Allah knows them.

  4. And those who are constant, seeking the pleasure of their Lord, and keep up prayer and spend (benevolently) out of what We have given them secretly and openly and repel evil with good; as for those, they shall have the (happy) issue of the abode

  5. And they who when they spend, are neither extravagant nor parsimonious, and (keep) between these the just mean.

  6. Surely they who recite the Book of Allah and keep up prayer and spend out of what We have given them secretly and openly, hope for a gain which will not perish.

  7. Believe in Allah and His Messenger, and spend out of what He has made you to be successors of; for those of you who believe and spend shall have a great reward.

  8. And what reason have you that you should not spend in Allah's way? And Allah's is the inheritance of the heavens and the earth, not alike among you are those who spent before the victory and fought (and those who did not): they are more exalted in rank than those who spent and fought afterwards; and Allah has promised good to all; and Allah is Aware of what you do.

  9. O you who believe! when believing women come to you flying, then examine them; Allah knows best their faith; then if you find them to be believing women, do not send them back to the unbelievers, neither are these (women) lawful for them, nor are those (men) lawful for them, and give them what they have spent; and no blame attaches to you in marrying them when you give them their dowries; and hold not to the ties of marriage of unbelieving women, and ask for what you have spent, and kt them ask for what they have spent. That is Allah's judgment; He judges between you, and Allah is Knowing, Wise.

  10. And if anything (out of the dowries) of your wives has passed away from you to the unbelievers, then your turn comes, give to those whose wives have gone away the like of what they have spent, and be careful of (your duty to) Allah in Whom you believe.
