Interest based earnings and profits

Assuming you are all Pakistanis and muslims. I have been a silent contributor of this community for quite long time. But when i see people talking about earning from interest based options and non of you guys tell him that's not permissible. I'm not one of those person who will say money doesn't matter. It does but at what cost? It depends on you. You can make your akhirat worst for some millions which is probably going to be spent by your kids. Think wisely before investing.
