Is it permissible to befriend someone

Q 3: What is the ruling on the following issue: I am a bachelor and I live with some colleagues. They only perform Salah (Prayer) in front of people. What is the ruling on living with them in this case?

A: If the reality is as you have mentioned, you have to advise them, perhaps Allah (Exalted be He) will guide them to the Truth through you. If they do not accept your advice, it will not be permissible for you to sit or live with them lest you should be affected by them. Hence, you have to abandon them and supplicate to Allah (Exalted be He) to guide them to the Truth.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
