Is a questioner excused for praying at home instead of the nearby Zawiya due to the mosque's distance, the presence of insults and curses outside the Zawiya, discomfort with the people inside, and the Zawiya not holding Friday prayers? Is his prayer at home accepted? And is he sinful if praying at the Zawiya is obligatory?

Your diligence in praying in the mosque carries a great reward, and there is no sin upon you if you pray in congregation at home, for congregational prayer is valid everywhere and does not require a mosque. Praying in congregation at the Zawiya, even if it is surrounded by reprehensible acts, is better than praying alone or in a small congregation at home. It is obligatory to perform prayer with the Muslims and to denounce evil. What you find in yourself towards the people of the Zawiya, if it is unjustified, try to get rid of it. Congregational prayer at home removes sin and fulfills the obligation, but praying in the mosque is better, and if that is not possible, then praying at the Zawiya is more proper and carries a greater reward.
