Imam Ja‘far as-Sadiq when Zulaykha decided to have sexual relations with Yusuf, there was an idol in the room. When she put a curtain on it, Yusuf asked the reason behind it. She said, she was ashamed of the idol.
“You are ashamed of the idol that neither sees nor hears you. Shall I not be ashamed of my Lord who is manifest and informed about everything?” asked Yusuf. Then he disengaged himself and tried to flee. Zulaykha pursued him and at that moment the ‘Aziz appeared at the doorway. Zulaykha asked him what the punishment was for a person who intended evil with his wife, except imprisonment or a painful punishment. Yusuf pleaded innocence and said she herself harbored evil intentions on him. There was an infant in the cradle at that time. The Almighty sent a revelation on Yusuf and he suggested to ‘Aziz that he ask the infant who was a witness of all that had passed. “He will tell you that I have not betrayed trust,” said Yusuf.
‘Aziz asked the child and the Almighty gave it the power of speech to testify in favor of Yusuf. The little child said, “If the shirt of Yusuf is torn from the front, Zulaykha speaks the truth and Yusuf is lying. But if his shirt has a tear at the back, Zulaykha is a liar and Yusuf is truthful.” ‘Aziz inspected the shirt of Yusuf and found that it was torn from behind. He told Zulaykha that it was her evil plot. And the guile of you women is great,” he added.
