Almighty Allah related the scene of the banquet in His words: So when she heard of their accusation, she sent for them and prepared a banquet for them; she gave each one of them a knife (to cut the foodstuff with), and she said (to Joseph): "Come out before them." Then, when they saw him, they exalted him (at his beauty) and (in their astonishment) cut their hands. They said: "How perfect is Allah (or Allah forbid)! No man is this! This is none other than a noble angel!"
She said: "This is he (the young man) about whom you did blame me (for his love), and I did seek to seduce him, but he refused. And now if he refuses to obey my order, he shall certainly be cast into prison, and will be one of those who are disgraced." Surah 31-32
