The Messenger of Allah ﷺ said, "A man was walking along a road when he became overwhelmed with thirst. He found a well, climbed down into it, drank, and came back out. Then he saw a dog panting and licking at the wet earth from thirst. The man said, 'This dog is suffering from thirst just as I was.' So he went back down into the well, filled his shoe with water, held it in his mouth as he climbed up, and gave the dog a drink. Allah appreciated what he had done and forgave him."They said, "Messenger of Allah, are we rewarded even for what we do for animals?"He replied, "There is a reward for whatever is done for any living creature."
و حدثني عن مالك عن سمي مولى أبي بكر عن أبي صالح السمان
أن رسول الله ﷺ قال بينما رجل يمشي بطريق إذ اشتد عليه العطش فوجد بئرا فنزل فيها فشرب وخرج فإذا كلب يلهث يأكل الثرى من العطش فقال الرجل لقد بلغ هذا الكلب من العطش مثل الذي بلغ مني فنزل البئر فملأ خفه ثم أمسكه بفيه حتى رقي فسقى الكلب فشكر الله له فغفر له فقالوا يا رسول الله وإن لنا في البهائم لأجرا فقال في كل ذي كبد رطبة أجر
