She said, "That is the one about whom you blamed me. And I certainly sought to seduce him, but he firmly refused; and if he will not do what I order him, he will surely be imprisoned and will be of those debased."
` She [ Zulaikha ] said: 'So, [ see ] this is the one you blamed me for. Yes, I seduced him, but he abstained. And should he [ in future ] not follow my command, he shall be [ surely ] imprisoned and shall be disgraced [ too ].'
When Zulaikha realized that her secret lay disclosed before those women anyway, she started threatening Sayyidna Yusuf (علیہ السلام) right before them. At that time, according to some commentators, all these women too started telling Sayyidna Yusuf علیہ السلام that Zulaikha was their benefactor, therefore, he should not oppose her.
Tazkirul Quran
Maulana Wahiduddin KhanOn ayahs 29–33
Joseph ran towards the door to save himself and Zulaykha also ran after him and caught hold of his shirt from behind. In this chaos the back of his shirt was torn. However, Joseph was able to open the door and came out. It so happened that Zulaykha’s husband was there outside the door. On seeing him, Zulaykha put all the blame on Joseph. She did not hesitate to make a false accusation against a person for whom she had been professing love only a moment earlier. Joseph said that the matter was entirely the opposite of what Zulaykha claimed. Now the question was to decide as to who was in the wrong. No third person was present on this occasion who could have been an eyewitness. At that time a wise person of the household offered good advice. (In all probability this person was already aware of the situation. Moreover, he might have already seen that Joseph’s shirt was torn from behind and not from in front.) He told all those concerned that, in the absence of an eyewitness, circumstantial evidence should be relied upon and the circumstantial evidence was that Joseph’s shirt was a clear proof of the fact that in this case it was not Joseph, but Zulaykha who had made improper advances.
