The ruling on combining two prayers due to dust
Machine translationRead the Arabic original
Question:
Abu 'Abd al-'Aziz says: If there is a lot of dust in the neighborhood, and it is not severe, but it may affect some of the worshippers, does that permit the imam of the mosque to combine the two prayers, as is done with heavy rain?
Answer:
No, there is no report that prayers are combined because of dust. The air is always free of dust, and there is no report that they are combined for that reason. Combining Maghrib and 'Isha' is only reported for rain that wets the clothes, or for mud from clay and water in the streets. In that case, Maghrib and 'Isha' are combined. Or combining while traveling, or combining due to illness. If the sick person needs to combine, he combines. Yes.
