Abu Huraira reported from Allah's Messenger (may peace be upon him) A hadith out of which one was this that Allah's Messenger (may peace be upon him) said: A woman got into Hell-Fire because of a cat whom she had tied, and thus it could not eat, and she did not let it free so that it could devour the insects of the earth, until it died.
