Verily, some of what reached people from the speech of the early prophets: If you feel no shame, then do whatever you wish

The Prophet (may Allah's peace and blessings be upon him) informed that among the teachings of the early prophets that were circulated among people and passed from one generation to another until reaching the early generation of this Ummah: Consider what you want to do and do it if it is not something to feel ashamed of; but leave it if it is something you feel ashamed of.

Modesty prevents committing villainous deeds, and one who has no share of modesty will indulge in all types of immoral and evil deeds.
