Q. I have roomies. They are Christian and Hindus. Can we wear each another’s clothing? (in office question)

A. If clothing fulfills Islamic requirements and are in the state of Islamic purity, then it can be worn.

Doing this would not function as a good habit. Muslim must wear Islamic clothing and do their sharing amongst themselves for they are part of each another. However, this does not negate its permissibility. It is always best to have people adopt your good Muslim clothing habits, then you adopting the habits of others.

Allah Certainly Knows Best.
