Attending parties that contain some evils

Q 1: I live with five of my friends. Despite that they perform the (Part No. 26; Page No. 78) obligatory five Salahs (Prayers) in the Masjid (mosque), at night they play cards, smoke cigarettes, and watch television. I sit in the room with them without being able to enjoin Ma`ruf (that which is judged as good, beneficial, or fitting by Islamic law and Muslims of sound intellect) or forbid Munkar (that which is unacceptable or disapproved of by Islamic law and Muslims of sound intellect) as they are a group and I am only one person. As we work together, I also eat with them. Please answer the following questions:A- Is it permissible for me to live in the same room with them?B- Is it permissible for me to perform Salah (Prayer) with them bearing in mind that they perform Salah regularly?C- Is it permissible for me to eat with them as the nature of my work does not enable me to cook for myself.

A: You may live with your colleagues mentioned in the question, even if they commit some sins such as smoking cigarettes and playing cards so long as they continue performing Salah regularly and that you advise them to give up these sins. However, if they do not heed your advice; you must leave them and live elsewhere.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
