salaam alaikum,

1. a muslim who beleives in shahadah goes to dargah to seek the help of dead saints, he will be still a muslim right?

because its an act of shirk as his heart believes that there is only Allah to help him/her.

2. a muslim beleives that alcohol is not haraam. is it kufr or an act of kufr? becoz s/he too beleives in Allah and Last Day.

hope u understood my point.
