Ruling 1477

When thunder, lightning, and other similar natural phenomena occur, if one wants to [perform ṣalāt al‐āyāt] as a precautionary measure, and if these phenomena last a long time, it is not necessary for him to perform the prayer immediately. In other cases, such as an earthquake, one must perform it immediately in a way that people would not consider it as being delayed; and if he does delay it, the recommended precaution is that he should perform it later without making an intention of adāʾ or qaḍāʾ.
