Reading qasr salaah at home
Q: I am staying in a hostel and doing my 1st year college. When I come home for the weekend, I offer salaah as a musaafir by offering 2 rakaats zuhr, 2 rakaats asr, 3 rakaats maghrib and 2 rakaats isha. My house is 177 km away from the hostel. Is it right? How many km should it be for me to be a musaafir?
