The Women - 4:6 Test the orphans when they reach the age of marriage. If you see maturity in them, give them their property. Do not eat their wealth in extravagance and haste, lest they grow up. Let the rich give up (the wages of his efforts to protect the property). Let the poor spend an appropriate amount. Return their property to them in the presence of witnesses. Allah is sufficient as the Reckoner.
