Re: Gay/lesbian friends
Yes. That is essentially in Quran.
Show me where Allah said in Quran how to punish homosexuals.
Look my friend you can keep going, but you need to read above for the answers already given.
As far as the act of homosexuality is concerned, there is no doubt it is wrong.
Socially one may choose not to associate with them which is the question of this thread.
Punishment is a different matter. It is not up to common people to worry about.
