Re: Non-Shias attending Shia majlises/milad- is it ok?
I am sure your dear grandmother appreciated this noble gesture by her best friends.
What was the response of your dear grandmother? Did she reciprocate the noble gesture by her best friends by accompanying them to Taraweeh prayers?
I am sure this gesture would have been appreciated by her best friends. (I am sure she did - she would not let her best friends down, would she?)
