Then she would resort to enticements in order to obtain her desire. She would promise to release him from prison, if he would but grant her wish. But… - Joseph

Zuleika saying, "If it be thy wish that I forsake idol worship, then fulfil my desire, and I will persuade that Egyptian husband of mine to abjure the idols, and we shall walk in the law of thy God." Joseph replied, "The Lord desireth not that those who fear Him shall walk in impurity, nor hath He pleasure in the adulterer."

she said to Joseph: "Why dost thou refuse to fulfil my wish? Am I not a married woman? None will find out what thou hast done."
Joseph replied: "If the unmarried women of the heathen are prohibited unto us, how much more their married women? As the Lord liveth, I will not commit the crime thou biddest me do."

And he left all that he had in Joseph's hand; and, having him, he knew not aught save the bread which he did eat. And Joseph was of beautiful form, and fair to look upon. And it came to pass after these things, that his master's wife cast her eyes upon Joseph; and she said: 'Lie with me.' But he refused, and said unto his master's wife: 'Behold, my master, having me, knoweth not what is in the house, and he hath put all that he hath into my hand; he is not greater in this house than I; neither hath he kept back any thing from me but thee, because thou art his wife. How then can I do this great wickedness, and sin against God?' And it came to pass, as she spoke to Joseph day by day, that he hearkened not unto her, to lie by her, or to be with her. And it came to pass on a certain day, when he went into the house to do his work, and there was none of the men of the house there within, that she caught him by his garment, saying: 'Lie with me.' And he left his garment in her hand, and fled, and got him out. [...] And she laid up his garment by her, until his master came home. And she spoke unto him according to these words, saying: 'The Hebrew servant, whom thou hast brought unto us, came in unto me to mock me. And it came to pass, as I lifted up my voice and cried, that he left his garment by me, and fled out.' And it came to pass, when his master heard the words of his wife, which she spoke unto him, saying: 'After this manner did thy servant to me'; that his wrath was kindled. And Joseph's master took him, and put him into the prison, the place where the king's prisoners were bound; and he was there in the prison.
