The right of your child is that you should know that he is from you and will be ascribed to you, through both his good and his evil, in the immediate affairs of this world. You are responsible for what has been entrusted to you, such as educating him in good conduct (husn al-adab), pointing him in the direction of his Lord, and helping him to obey Him. So act toward him with the action of one who knows that he will be rewarded for good doing toward him and punished for evildoing.
