Sahih Muslim
The Book of Virtue, Good Manners and Joining of the Ties of Relationship (Kitab Al-Birr was-Salat-I-wal-Adab)

This hadith has been reported on the authority of Ibn 'Umar through another chain of transmitters. And Ibn 'Umar reported Allah's Messenger (may peace be upon him) as saying: A woman was tormented because of a cat which she had tied and thus allowed it neither to eat or drink nor set it free so that it might eat the insects of the earth.
