Re: I am confused.....
If Shiraz repents sincerely and resolves to never go back to drinking, he will be forgiven inshAllah taala.
As for trying to get someone out of a mess, you first have to make your imaan 10 times strong so you dont fall into peer pressure. It would be better that Shiraz leaves waseem's company until he finds himself strong enough to try to show someone the correct path. There is nothing WORST than a bad company.
