The ruling on combining prayers during rainfall

Question:
Another person says: After the rains have become frequent in these days, and praise be to Allah, Lord of the worlds, what is the ruling on combining the Maghrib prayer with the 'Isha' prayer while it is raining at the time of Maghrib, and which is better, combining them or not?

Answer:
This varies. If the rain is heavy and causes harm to passersby, then this permits combining the Maghrib and 'Isha' prayers, and according to the correct view, it also permits combining the Zuhr and 'Asr prayers if there is a need. However, if it is light rain and there is no mud in the paved, asphalted markets, and the rain is slight and causes no harm, then pray each prayer in its proper time. But if hardship arises from the rain or from mud in the markets, there is no harm in combining them.
