[2:278] O you who believe, fear God, and give up the usury that is outstanding, if you are believers.
Being content with what is promised (mawʿūd) by the Lord is better for the one who submits than attaching one's heart to what the lower self seeks (maqṣūd). What you seek (maqṣūd) is from the seductions of the lower self, while what you have been promised (mawʿūd) has been guaranteed by the Real.
