(14) "And take in thy hand a little grass, and strike therewith: and break not (thy oath)." Truly We found him full of patience and constancy. How excellent in Our service! ever did he turn (to Us)!

And if any one earns any good, We shall give him an increase of good in respect thereof: for Allah is Oft-Forgiving, Most Ready to appreciate (service).

(16) If ye loan to Allah, a beautiful loan, He will double it to your (credit), and He will grant you Forgiveness: for Allah is most Ready to appreciate (service), Most Forbearing,-
