Granted paradise

Prophet Muhammad ( peace be on him) once told a story to his companions. There was a man who went on a journey and on his way felt very thirsty. He found a well and went down into it and drank water. When he came out of the well he saw a dog who was also very thirsty and was licking the salty ground with his tongue. Thinking that the animal was thirsty like him, he again went down into the well, filled his leather socks with water and gave it to the dog. Allah was so pleased with this action of the man that he granted him Paradise
