Asalamu alaykum brothers and sisters,
I have a slight problem. I have friends who are staying at my house for a few days. Some of them drink, and I have told them that I do not allow alcohol in my home, however they would like to drink. I told them they can drink outside. Is this permissible if they are in my backyard drinking? I do not want alcohol in my home as the angels do not enter the home when alcohol is present.

Please assist. Thank you.
