' Aishah narrated that when the Prophet(saw) saw a cloud approaching from any horizon, he would stop what he was doing, even if he was praying, and turn to face it, then he would say: (O Allah, we seek refuge with You from the evil of that with which it is sent)." Then if it rained he would say: (O Allah, a beneficial rain),” two or three times. And if Allah dispelled it and it did not rain, he would praise Allah for that. (Sahih)
