What is the criterion for combining the two prayers in the rain, and is it permissible to combine them due to strong wind?

Question:
The questioner: What is the criterion for combining the two prayers in the rain, and is it permissible to combine them during strong winds and dust?

Answer:
The rain that falls during the prayer on the road reaches the level of choice, and one combines the prayers for its sake. However, if the rain stops, the prayers are not combined unless there is mud and slush in the road, in which case one would slip from the mosque. As for the wind, it is described with various attributes: a strong, cold wind on a dark night. If these attributes are present—that it is strong, that it is cold, and that it is on a dark night—then a group of scholars hold that one combines the prayers for its sake. If it is not so, then one does not combine the prayers for its sake. As for dust, one does not combine the prayers for its sake. None of the Salaf or the predecessors combined the prayers for dust, nor did they mention it as one of the causes for combining. Yes.
