I have following questions:
1 - Why is "shirk" been declared as a sin which will not be forgiven in any case. A Buddhist friend of mine says that isn’t God very selfish while declaring this? Kindly, respond and also tell the effect of "shirk" on worldly life?
2 - My second question is regarding the act of zina. A person who is committing zina or (in second case) going near zina, answerable to God only or the society as well? Can some body say, to the person who is committing zina or going near, that you are answerable to us as well?
3- Thirdly, if one comes to know that an individual near him or in his community is doing something wrong, what should be the right approach towards his correction?
