" (A dervish was tempted by the devil to cease calling upon Allah, on the ground that Allah never answered, “Here am I.” The Prophet Khadir appeared to him in a vision with a message from God.) Was it not I who summoned thee to my service? Was it not I who made thee busy with my name? Thy calling “Allah!”was my “Here am I.” Jalal-uddin Rumi "
