In some cities, the sun does not rise at all for days or does not set at all for days or even more. How should we pray and fast?
Answer
As for salat, one should, as a matter of obligatory precaution, observe the closest place that has night and day in a twenty-four hour period, then say salat according to its timings with the intention of mutlaqa [i.e., just qurbatan ilal lah without specifying whether it is ada (on time) or qadha (after time)]. As for fasting, it is obligatory upon you to move during the month of Ramadhan to another city where you can observe fasting of this holy month, or move to that city after that month to perform it qadha.
