In the last two (28 29) of the verses cited above, it has been stated that the ` Aziz of Misr had already realized by having heard the child speak in the manner he did that some special supernatural situation was there to demonstrate the innocence of Sayyidna Yusuf (علیہ السلام) . After that, according to what the child had said, when he saw that the very shirt of Sayyidna Yusuf (علیہ السلام) is really torn up from the back, he became certain that it was Zulaikha who was at fault and it was Sayyidna Yusuf (علیہ السلام) who was innocent. So, first he addressed Zulaikha and said: إِنَّهُ مِن كَيْدِكُنَّ that is, all this is a guile of yours whereby you wish to pass on your wrongdoing to someone else. Then he said that great is the guile of women for it is difficult to understand and not easy to get out from. The reason is that they outwardly give the impression of being soft, delicate, even weak. A non-discerning onlooker is likely to believe in what they say. But, given a lack of wisdom and honesty, that could be a web of deception. (Mazhari)

According to a narration of Sayyidna Abu Hurairah ؓ عنہ appearing in the Tafsir of Al-Qurtubi, the Holy Prophet is reported to have said: The guile of women is stronger than the guile of Shaytan - because, about the guile of the Shaytan, Allah Ta ala has said that it is weak: كَيْدَ الشَّيْطَانِ كَانَ ضَعِيفًا (4:76); and about the guile of women, it was said: إِنَّ كَيْدَكُنَّ عَظِيمٌ (great is the guile of you women - 12:28). And it is obvious that not all women are meant here. Instead, meant here are only those of them who are involved in practicing guiles and excuses.
