And test (and try) the orphans until they are of marriageable age. If you find they have acquired sound judgement, then hand over their property to them; but devour not their wealth, nor use it up hastily out of fear that soon they will grow up (and demand it). And (the guardian) who is rich should abstain from spending much (of their wealth); and he who is poor should use only as much as is fair. And when you give back their possessions have this witnessed, (and remember) that God is sufficient to take all account.
— Quran 4:6
