Prayer: If people live in two places seasonally, are both considered watan? How should they pray when travelling between them?

English:

Question #642:

Some tribes live in a winter resort for three or four months and in a summer resort for the rest of the year or vice versa. Are these two places considered their watan? When they are residing in one of them, they may have a trip to the other. How should they pray?

Answer #642:

If they intend to continue going back and forth permanently between the summer and the winter resorts, spend some days of the year in one and other days in the other one, and choose both places as their permanent settlements or for many consecutive years, then both places are regarded as their watans. If the distance between the two watans equals or exceeds the shar‘ī distance, while traveling from one watan to the other, their rule is that of other travelers.
