Attribute your adoptees to their fathers, that is more just and more upright with Allah, then if you did not know their real fathers then call them at that time by the brotherhood of religion which joins you with them, for they are your brothers in the religion and your allies therein, and there is no sin upon you in what you fell into of mistake which you did not intend, but only Allah takes you to task if you intended that. And Allah was Forgiving to whoever erred, Merciful to whoever repented from his sin.
