Narrated Anas Ibn Malik: He said, "We were with the Messenger of Allah (ﷺ), At one point it started raining on us. Then the Messenger of Allah (ﷺ) lifted some part of his clothes so that the rain water would fall on him. We ask, “O Messenger of Allah! Why did you do that? ” He said, "It has just come from his great Lord!"
