I currently work as a private tutor for a middle-school girl. She and her family are non-Muslims. My tutoring job starts at 4.30 PM and ends at 6.30 PM. I come to their house to tutor the girl. Adhan for Maghrib prayer (salat) comes in the middle of teaching time, at about 5.49 PM.
Shall I wait till 6.30 PM to do Salat in the nearby Masjid (mosque) or shall I just do Salat in the middle of teaching, and in their house? With knowing that Maghrib time ends at about 7.00 PM?
I just feel kind of awkward to do Salat in their house. But either, I don't wanna hurt their feelings to leave the house at the beginning of maghrib time to do salat and come back again to tutor their daughter.
Is there anything in Islam that rules where we do Salat and where we don't?
