And try orphans ( as regards their intelligence ) until they reach the age of marriage ; if then you find sound judgement in them , release their property to them , but consume it not wastefully , and hastily fearing that they should grow up , and whoever amongst guardians is rich , he should take no wages , but if he is poor , let him have for himself what is just and reasonable ( according to his work ) . And when you release their property to them , take witness in their presence ; and Allah is All-Sufficient in taking account .
