English translation
2550. It was reported from Abū Hurairah that the Messenger of Allāh ﷺ said: "Once while a man was walking on the road, he became extremely thirsty. He found a well and went down into it. He drank from the water and came out. He saw a dog panting heavily and eating soil due to its thirst. The man said: 'This dog must be in the same condition of thirst as I was,' so he went down into the well, and filled his Khuff with water, and held it by his mouth until he climbed up. He gave water to the dog to drink. Allāh accepted his deed and forgave him." They said: "O Messenger of Allāh! Are there rewards for us in our animals?" He said: "For every moist liver (living creature) there is a reward."(Sahīh)
