Zina takes everything from you. It is one of a few sins the Quran calls pure filth. Zina is a chain reaction, it starts with a glance, then a smile, a message, a meeting until one day your heart has already crossed the line and the body simply follows. That's why Allah didn't say don't commit zina, Allah says do not go even near it. Because the paths leading to Zina are as destructive as Zina itself.
