Q: When we go for umrah, all the umrah busses stop for asr prayer according to shafiee time. We (ladies) strictly follow hanafi time. In winters, due to school, we read our zuhur salah after the shafiee asr azan, as hanafi zuhur salaah time is still there. We also read our asr according to hanafi time i.e. late.

So my question is... the bus stops for asr at shafiee time. If we do not get the jamaat, what should we do? Can we read at shafiee time at such circumstances?
