(114) باب مَا يَقُولُ إِذَا هَاجَتِ الرِّيحُ
Narrated Aisha, Ummul Mu'minin:
When the Prophet (ﷺ) saw a cloud formation in the sky, he left work, even if he were at prayer, and then would say: "O Allah! I seek refuge in Thee from its evil. " If it rained, he would say: "O Allah! send a beneficial downpour."
