Tawakal

Al-Khuldi, the pupil, relates that he went to Junayd and found him suffering from a fever. "O Master," he cried, "tell God in order that He may restore thee to health." Junayd said: "Last night I was about to tell Him, but a voice whispered in my heart, 'Thy body belongs to Me: I keep it well or ill, as I please. Who art thou, that thou shouldst interfere with my property."
