Qasar Namaz In Travelling
What I understand from clips of Al Mawrid scholars Qasr namaz is read in a situation like a long overseas travel. Or where circumstances render it impossible to read prayers in time. Like a surgeon operating. I have not heard of a fixed time period of 6 days or as one also heard 15 days maximum. I think one can go back to normal prayers as soon as the circumstances permit but obviously this differs from person to person.
