Musannaf Ibn Abi Shaybah 37438 — The words of Abu Hurayrah

It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that he said: A man passed by a dog lying beside a well, a dog that was close to death from thirst. The man found nothing with which to give it water, so he took off his leather sock, scooped up water for it and gave it to drink. So Allah Almighty dealt with his account and admitted him to Paradise.
