Ar-Rashid
The Righteous Teacher

We shall teach thee, and thou wilt not forget aught of what thou art taught, save what God may will
thee to forget -- for verily, He alone knows all that is open to man's perception as well as all that is hidden from it -- and thus shall We make easy for thee
the path towards ultimate ease.
Al-A'la 87:7-8, tr. Asad
God turns you from one feeling to another
and teaches by means of opposites,
so that you will have two wings to fly,
not one.
