Narrated by 'Aisha
'Aisha, the wife of the Apostle of Allah (may peace be upon him). said: I heard Allah's Messenger (may peace be upon him) as saying: Four are the vicious (birds, beasts and reptiles) which should be killed in the state of Ihram or otherwise: kite (and vulture), crow, rat, and the voracious dog I (one of the narrators, 'Ubaid-ullah b. Miqsam) said to Qasim (the other narrator who beard it from 'Aisha): What about the snake? lie said: Let it be killed with disgrace.
