Is the prayer valid in a house where there is presence of any alcoholic beverages? Are we allowed to go to their house if they are our relatives?
Yes, prayer is valid in a house which has alcoholic drinks as far as the place of Prostration is Tahir. We should avoid any act which gives others an impression that we approve their drinking alcohol. We are allowed to visit our relatives who keep alcohol at their house with out approving their sinful acts.
Wassalam.
