My cousin who is a muslim and works with a bank manager as his personal assistant complained to me that on some sundays,he had had to follow his boss to church on special occassions.
Most times,He stay outside the church until his boss had to complain through a third party that he doesnt stay in the church.So is he allowed to stay in the church even though that does not affect his faith,
thanks

You should advise your cousin to stay away from the act. tell him there is no obedience to anybody while disobeying the Creator. He has nothing to benefit from Church except Kufr and blasphemy. His boos is only looking for away of wooing him to their midst.

in the first place he has to even find out the ruling for a Muslim working any a bank. Please it is very crucial. Maybe if you need more information, you can let me know.

At first, for the boss to complain through third part shows that he has hidden motive. Is he affecting for him to stay outside. Just advise your cousin to watch closely and be careful.

tell ur cousin that going to church will do alot of good.that is where the true God resides. there is no good place like the presence of GOD!
