Question #672:

What rule applies to the prayer and fasting of someone who is propagating Islam in two locations and intends to stay in that area for ten days?

Answer #672:

If they are considered as two locations according to the common view, it will not be correct for him to make the intention of staying for ten days in both of them, or in one of them as long as he intends to go back and forth between the two during the ten days.
