Hadith 542
Sayyiduna Mahmud bin Rabi’ (may Allah be pleased with him) narrates: Sayyiduna Suraqah bin Ju’sham (may Allah be pleased with him) submitted: O Messenger of Allah! If a lost camel comes to my pond and I give it water to drink, will there be a reward for that? The Prophet (peace and blessings of Allah be upon him) said: “Give it water to drink, for there is a reward in doing good to every living being.”
