And test the orphans [in your charge] until they reach a marriage­able age; then, if you find them to be mature of mind, hand over to them their possessions; and do not consume them by wasteful spending, and in haste, ere they grow up. And let him who is rich abstain entirely [from his ward's property]; and let him who is poor partake thereof in a fair manner. And when you hand over to them their possessions, let there be witnesses on their behalf - although none can take count as God does.
