Abu Hurayrah (may Allah be pleased with him) said: Once a strong wind overtook the people while they were on the road to Makkah, and Umar (may Allah be pleased with him) was going for Hajj, and the wind became very severe. So Umar (may Allah be pleased with him) asked the people around him: "What is the wind?" But they gave him no answer. Then the news reached me that Umar (may Allah be pleased with him) had asked this question, so I urged my mount towards him until I caught up with him, and I said: O Commander of the Believers! I have been told that you asked about the wind, and I heard the Messenger of Allah (peace and blessings be upon him) say: "The wind is from the mercy of Allah; it brings mercy and it brings punishment, so do not curse it. Ask Allah Almighty for its good and seek refuge in Him from its evil."
