Working during the time of congregational

Q: I am eighteen years old and I live in the Kingdom of Saudi Arabia, in Jeddah. I work as a guard at a Saudi man's villa. The man's father is elderly, so I do not leave him alone except at the time of Salah (Prayer), but he does not want me to offer Salah in the Masjid (mosque). When he knows that I have offered Salah in the Masjid, he beats me and threatens to send me back to my country. I do not want to be sent to my country; however, I am keen on offering Salah in the Masjid, and my conscience troubles me if I do not. This man does not offer Salah in the Masjid except for Jumu`ah (Friday) Prayer, and sometimes does not offer it at all claiming that he overslept. This might take place for three or four consecutive weeks. Please give me your advice concerning this matter. I like to offer congregational Salah in the Masjid; however, this man who is so easily irritated sometimes prevents me from going to the Masjid early on Friday, although I am a young man and I want to go early. Please advise me, and many thanks to you.

(Part No. 7; Page No. 303) A: You should offer the five congregational Salahs in the Masjid, and you should be patient and confidently anticipate Allah's Recompense. Allah will bring about ease after hardship. And whosoever fears Allâh and keeps his duty to Him, He will make a way for him to get out (from every difficulty). And He will provide him from (sources) he never could imagine. And whosoever puts his trust in Allâh, then He will suffice him. Verily, Allâh will accomplish his purpose. Indeed Allâh has set a measure for all things. Be advised that no one should be obeyed in matters that involve disobedience to Allah. If you obey Allah, He will support you.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
