Animal
ShaikhAbu Hurayra reported that the Messenger of Allah, may Allah bless him and grant him peace, said, “One day a man became very thirsty while walking down the road. He came across a well, went down into it, and drank and then climbed out. In front of him he found a dog panting, eating the dust out of thirst. The man said, “This dog is as thirsty as I was.” He went back down into the well and filled his shoe, putting it into his mouth (in order to climb back up) and then gave the dog water. Therefore Allah thanked him and forgave him.” They said, “Messenger of Allah, will we have a reward on account of animals?” He said, “There is a reward on account of every living thing.” (Bukhari)
Shaikh Abdullah ibn “Umar reported that the Messenger of Allah, may Allah bless him and grant him peace, said, “A woman punished her cat by imprisoning it until it died of hunger and because of it, she entered the Fire. It was said – and Allah knows best:
“You did not feed it nor give it water when you imprisoned it nor did you release it and let it eat from the plants of the earth.” (Bukhari)
Shaikh Abu Umama that the Messenger of Allah, may Allah bless him and grant him peace, said, “Anyone who shows mercy, even to an animal meant for slaughtering, will be shown mercy by Allah on the Day of Rising.” (Bukhari)
It is reported from Mujahid that Ibn “Umar disliked making animals fight each other. (Bukhari)
