Allah, Exalted is He, enjoined Muslims to show mercy to all creatures, and decreed that Islam should be the religion of mercy, kindness, and benevolence. Given the significant care and attention assigned to this fundamental Islamic principle, Muslims are enjoined to show mercy to all living beings, including animals, and are promised abundant rewards for it. In this hadeeth, Aboo Hurayrah (may Allah be pleased with him) related that the Messenger of Allah ﷺ said: “While a man was walking,” the apparent indication of the hadeeth’s wording is that this man belonged to the previous nations; “he felt thirsty and went down a well and drank water from it. On coming out of it, he saw a dog panting.” It means that the dog was out of breath or sticking his tongue out due to excessive thirst, “and eating mud because of excessive thirst,” meaning that it was licking dust out of thirst. “The man said, 'This (dog) is suffering from the same problem as that of mine. So, he (went down the well), filled his shoe with water, caught hold of it with his teeth and climbed up and watered the dog.” The Prophet ﷺstated that this man took off his shoe, held it in his hand, went down the well, filled his shoe with water, caught hold of it with his teeth, and climbed up and watered the dog, to indicate the difficulties he had to face in the process.The same goes for the reference to holding the shoe with his own teeth to bring water to this thirsty dog. Therefore, “Allah thanked him for his (good) deed and forgave him." Allah, Exalted is He, knew of his act and rewarded it by forgiving his sins. The version recorded by Al-Bukhaaree reads: “Allah thanked him for his (good) deed, forgave him, and admitted him to Paradise.” The Prophet ﷺ used the verb ‘thank’ to denote reward, because thanking or appreciation is a form of reward. When the Companions (may Allah be pleased with them) heard the story, they asked the Prophet ﷺ whether or not one earns reward for serving animals. He ﷺ replied, "Yes, there is a reward for serving any living being,” meaning that showing mercy and kindness to any living being is a rewardable act in Islam. The Arabic word used in the hadeeth, ‘Kabid,’ literally means ‘liver’ and is used to refer to every living being because the liver needs water to live, otherwise an animal would die. The hadeeth means that doing any merciful act or act of kindness to an animal, by serving it water or food or protecting it from heat or coldn, whether or not it is owned by the doer, others, or is not owned by anyone, is a good act for which Allah, Exalted is He, will reward the doer. The hadeeth urges Muslims to show kindness to people, because if one earns the forgiveness of Allah, Exalted is He, for serving water to a thirsty dog, this essentially means serving water to a thirsty person is even more rewardable. It also underlines the virtues of serving water to others,and that it is a great means to draw closer to Allah, Exalted is He. It also discourages Muslims from abusing or harming animals. .
