Train and educate the orphans well. When they reach the age of marriage, and attain sound judgment, release their property to them. The marriageable age shall mean attainment of physical and mental maturity when one can legally make a solemn contract (4:21). Do not consume their property or let it be wasted. Nor hastily spend it fearing that they will come of age. If the guardian is well off, let him claim no compensation for the management of the property. But, if he is poor he may have a just and reasonable amount. When you are releasing the property to the orphans be sure to take witnesses. Remember that Allah is Competent in taking account.
