How are fasting and prayer observed at the South and North Poles?

Question

How do the Muslims of the North Pole and the South Pole, where night lasts six months and day lasts six months, fulfil fasting and prayer: according to clock hours or according to [the cycle of] day and night?

Answer

What happens at the North and South Poles, and how those people perform fasting and prayer — obtain the answer to this from them, and then send it to me as well; after that it will be examined whether their practice conforms to the Shari‘a or not.
