Translation of the verse 23 from Surah Yusuf : Number of verses 111 - - page 238 - Part 12.
And she, in whose house he was, sought to seduce him (to do an evil act), she closed the doors and said: "Come on, O you." He said: "I seek refuge in Allah (or Allah forbid)! Truly, he (your husband) is my master! He made my stay agreeable! (So I will never betray him). Verily, the Zalimun (wrong and evil-doers) will never be successful."
And she, in whose house he was, sought to seduce him. She closed the doors and said, "Come, you." He said, "[I seek] the refuge of Allah. Indeed, he is my master, who has made good my residence. Indeed, wrongdoers will not succeed."
(12:23) Now the woman in whose house he was began to tempt him, and one day she closed the doors and said, "Come here." Joseph replied, "May Allah protect me from this! My Lord has given me a good abode: (and should I, then, misbehave like this?) Such workers of iniquity never fare well. " *21
*21) Generally the commentators and translators are of the opinion that Prophet Joseph used (Rabbi "My Lord") for the master of the house, and what he meant to imply by way of argument was this: "My Lord has treated me very kindly and kept me well in the house. How can I, then, be so disloyal and ungrateful as to commit adultery with his wife?" I, however, strongly differ with such a translation and commentary. Though the Arabic usage of (rabb) admits of such a meaning, I have two strong reasons against this here. First, it is far below the dignity of a Prophet to refrain from a sin because of the regard he had for some person other than AIlah. Second, there is not a single instance in the Qur'an that a Prophet ever called anyone other than Allah his "rabb." Prophet Joseph himself differentiates between his creed and that of the Egyptians making it plain that his ( "rabb" : Lord) was Allah, while they had made other human beings their "rabb". Then this verse should be considered from another point of view: when ("rabbi") may also mean "My Lord", Prophet Joseph might have invoked Allah. Why should then one take the other meaning, "my master", which most surely implies something that is against the right creed?
