The ruler's wife invited the city's women to a feast. What did the women do when they saw Joseph?
They cut their hands with the knife that the ruler's wife had given them
And women in the city said: The ruler's wife is asking of her slave-boy an ill- deed. Indeed he has smitten her
to the heart with love. We behold her in plain aberration.
And when she heard of their sly talk, she sent to them and prepared for them a cushioned couch (to lie on at the feast)
and gave to every one of them a knife and said (to Joseph): Come out unto them! And when they saw him they exalted him and
cut their hands, exclaiming: Allah Blameless! This is no a human being. This is not other than some gracious angel.
