“But when the messenger came to him” and said, “Respond to the king,” Joseph refused to leave with the messenger until his innocence had been made manifest. Then he said to the messenger, “Return to your master”—meaning, the king—“and ask him about the women who cut their hands.” He did not explicitly mention the wife of al-Aziz, out of courtesy and respect.
The Prophet, peace and blessings be upon him, said: “Had I remained in prison for as long as Joseph remained, I would have answered the caller.” (1)
“Indeed, my Lord is fully aware of their plot”: that is, Allah knows what they did.

It was also said that the women turned to the wife of al-Aziz and pressed her for an admission, [and she confessed] (2). Another view is that she feared they would testify against her, so she confessed. “It was I who sought to seduce him, and he is certainly telling the truth”—in his statement, “She sought to seduce me.” When Joseph heard this, he said: (3)
