Beautiful Hadith is about Kindness to Animals

Narrated `Abdullah bin `Umar RA: Allah's Messenger (peace be upon him) said, "A woman was tortured and was put in Hell because of a cat which she had kept locked till it died of hunger." Allah's Messenger (peace be upon him) further said, (Allah knows better) Allah said (to the woman), 'You neither fed it nor watered when you locked it up, nor did you set it free to eat the insects of the earth." (Bukhari - Vol. 3, Book 40, Hadith 553)
