Test the orphans until they reach the age of marriage , and then if you find them mature of mind hand over to them their property , and do not eat it up by either spending extravagantly or in haste , fearing that they would grow up ( and claim it ) . If the guardian of the orphan is rich let him abstain entirely ( from his ward 's property ) ; and if he is poor , let him partake of it in a fair measure .
