﴿ فَلَمَّا سَمِعَتْ بِمَكْرِهِنَّ أَرْسَلَتْ إِلَيْهِنَّ وَأَعْتَدَتْ لَهُنَّ مُتَّكَـًۭٔا وَءَاتَتْ كُلَّ وَٰحِدَةٍۢ مِّنْهُنَّ سِكِّينًۭا وَقَالَتِ ٱخْرُجْ عَلَيْهِنَّ ۖ فَلَمَّا رَأَيْنَهُۥٓ أَكْبَرْنَهُۥ وَقَطَّعْنَ أَيْدِيَهُنَّ وَقُلْنَ حَٰشَ لِلَّهِ مَا هَٰذَا بَشَرًا إِنْ هَٰذَآ إِلَّا مَلَكٌۭ كَرِيمٌۭ ﴾

“Thereupon, when she heard of their malicious talk, she sent for them, and prepared for them a sumptuous repast, and handed each of them a knife and said [to Joseph]: "Come out and show thyself to them!" And when the women saw him, they were greatly amazed at his beauty, and [so flustered were they that] they cut their hands [with their knives], exclaiming, "God save us! This is no mortal man! This is nought but a noble angel!"”
