The 'I must pray' Muslims, I can understand them. Because Friday
prayers are the only time which need to be done in a mosque. The
other prayers can be done anywhere.
I faced this problem when I was in poly. I had lecture/lesson from
1pm to 2pm. What i did was to go for prayers once every 3 weeks,
meaning 2 weeks go for class, 1 week go to mosque. But I make sure
i tell my tutor.
Maybe to be fair to all, Muslim men on Friday can either
start work 1 hour earlier or end 1 hour later (like start at 8am
instead of 9am or end at 6pm instead of 5pm).
I'm a Muslim. I know some Muslims are just bochap abt this.
