Silsilat al-Ahadith al-Sahihah

It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Once a dog was circling around a well, thirst was about to kill it. Suddenly, one of the immoral women from among the women of Bani Israel saw it. She took off her shoe and, using it, drew water from the well and gave it to the dog to drink. Because of this action, she was forgiven."
