Harun ibn Sa‘id al-Ayli and Ahmad ibn ‘Isa narrated to us; they said: Ibn Wahb informed us; Makhramah ibn Bukayr informed me, from his father, who said: I heard ‘Ubayd Allah ibn Miqsam say: I heard al-Qasim ibn Muhammad say: I heard ‘A’ishah, the wife of the Prophet, peace and blessings be upon him, say: I heard the Messenger of Allah, peace and blessings be upon him, say: "Four are all vicious, and they are killed in the sacred precinct and outside it: the kite, the crow, the rat, and the biting dog." He said: I said to al-Qasim: "What do you think of the snake?" He said: "It is killed, however small it may be."
