"Aisha, the wife of Allah's Apostle, reported: 'Allah's Messenger left my
apartment during the night. Then he came and he saw me in an agitated state.'
He said: "Aisha, what has happened to you? Do you feel jealous?" I said: "How
can it be that a girl like me would not feel jealous in regard to a husband like
you? Thereupon Allah's Messenger said: "It is your devil who has come to
you." I said: "Allah's Messenger, is there a devil with me?" He said: "Yes." I
said: "Is there a devil attached to everyone?" He said: "Yes." I said: "Allah's
Messenger, is there a devil attached to you also?" He said: "Yes."--(Sahih Muslim:Vol.014,Book 39,No.6759
