And with Joseph two other slaves entered the prison. One of them said: "I saw myself pressing wine in a dream"; and the other said: "I saw myself carrying bread on my head of which the birds were eating." Both said: "Tell us what is its interpretation; for we consider you to be one of those who do good." 36 Joseph said: "I will inform you about the interpretation of the dreams before the arrival of the food that is sent to you. This knowledge is part of what I have been taught by my Lord. I have renounced the way of those who do not believe in Allah, and who deny the Hereafter, 37 And I have followed the creed of my fathers, Ibrahim and Is'haq and ya'qub: it is not for us to associate aught with Allah. That is of Allah's grace upon us and upon mankind; but most of mankind thank not. 38 Say, which is better, my fellow-prisoners -- many gods at variance, or God the One, the Omnipotent? 39 (What) you worship besides Him are nothing but names that you and your fathers have assigned, for which no sanction has been sent down by God. Authority belongs to God alone. He commands that you worship none but Him. This is the right way; but most men are ignorant. 40 Fellow-prisoners, as for one of you, he shall pour wine for his lord; as for the other, he shall be crucified, and birds will eat of his head. The matter is decided whereon you enquire.' 41 He said to the one he thought would be saved, "Mention me to your master." However Satan made him forget to mention him to his master, and so Joseph remained in prison for a number of years. 42
