Narrated 'Aishah [may Allah be pleased with her]:
"When the Prophet (ﷺ) saw storm clouds he would pace back and forth. And when it rained, he would relax." She said: "I said something to him about that, and he said: 'What do I know? Maybe it is as Allah, Most High said: Then, when they saw it as a dense cloud approaching their valleys, they said: "This is a cloud bringing us rain (46:24)."' (PT)
