How do Shahrayar and Shahzaman prove to themselves that women are by nature faithless?

Shahrayar and Shahzaman, characters from "One Thousand and One Nights," become convinced of women's faithlessness through their personal betrayals. Shahrayar discovers his wife's infidelity, which fuels his distrust, while Shahzaman finds his own spouse in a similar act of betrayal. Their experiences lead them to generalize that all women are unfaithful, prompting them to take drastic actions against women as a result of their disillusionment. This perspective reflects their emotional pain and reinforces a cycle of mistrust and vengeance.
