What is the ruling on combining the Zuhr and 'Asr prayers, and likewise the Maghrib and 'Isha' prayers, on winter days?

Question:
He asks and says: What is the ruling on combining the Zuhr and 'Asr prayers, and likewise the Maghrib and 'Isha' prayers, on winter days? May Allah reward you with good.

Answer:
Combining is not permissible except in specific circumstances. For instance, if a sick person needs to combine, he combines.
Likewise, a traveler who needs to combine, specifically a traveler who shortens the prayer, combines if he needs to. Also, in the case of rain in the town, if there is heavy rain that soaks the clothes and people are distressed by it, and there is mud and clay on the way to the mosque that they slip in, then in this case they combine the Maghrib and 'Isha' prayers. This is the well-known position among the scholars of knowledge. As for combining the Maghrib and 'Asr, this is questionable, and combining the Zuhr and 'Asr in this case is left out.
