The right of the one who trains you through knowledge is magnifying him, respecting his sessions, listening well to him, and attending to him with devotion. You should not raise your voice toward him. You should never answer anyone who asks him about something, in order that he may be the one who answers. You should not speak to anyone in his session nor speak ill of anyone with him. If anyone ever speaks ill of him in your presence, you should defend him. You should conceal his faults and make manifest his virtues. You should not sit with him in enmity or show hostility toward him in friendship. If you do all of this, God's angels will give witness for you that you went straight to him and learned his knowledge for God's sake, not for the sake of the people.
