Qur'an 12:51

قَالَ مَا خَطْبُكُنَّ إِذْ رَٰوَدتُّنَّ يُوسُفَ عَن نَّفْسِهِۦ ۚ قُلْنَ حَـٰشَ لِلَّهِ مَا عَلِمْنَا عَلَيْهِ مِن سُوٓءٍ ۚ قَالَتِ ٱمْرَأَتُ ٱلْعَزِيزِ ٱلْـَٔـٰنَ حَصْحَصَ ٱلْحَقُّ أَنَا۠ رَٰوَدتُّهُۥ عَن نَّفْسِهِۦ وَإِنَّهُۥ لَمِنَ ٱلصَّـٰدِقِينَ

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.
