Yusuf - 12:51

قَالَ مَا خَطْبُكُنَّ إِذْ رَاوَدتُّنَّ يُوسُفَ عَن نَّفْسِهِ قُلْنَ حَاشَ لِلّهِ مَا عَلِمْنَا عَلَيْهِ مِن سُوءٍ قَالَتِ امْرَأَةُ الْعَزِيزِ الآنَ حَصْحَصَ الْحَقُّ أَنَاْ رَاوَدتُّهُ عَن نَّفْسِهِ وَإِنَّهُ لَمِنَ الصَّادِقِينَ
[12:51]
He said: How was your affair when you sought Yusuf to yield himself (to you)? They said: Remote is Allah (from imperfection), we knew of no evil on his part. The chief's wife said: Now has the truth become established: I sought him to yield himself (to me), and he is most surely of the truthful ones.
(The king) said (to the ladies): "What was your affair when ye did seek to seduce Joseph from his (true) self?" The ladies said: "Allah preserve us! no evil know we against him!" Said the 'Aziz's wife: "Now is the truth manifest (to all): it was I who sought to seduce him from his (true) self: He is indeed of those who are (ever) true (and virtuous).
He (the king) (then sent for those women and) said: What happened when ye asked an evil act of Joseph? They answered: Allah Blameless! We know no evil of him. Said the wife of the ruler: Now the truth is out. I asked of him an evil act, and he is surely of the truthful.
