Zaid b. Jubair reported:
A person asked Ibn 'Umar which beast a Muhrim could kill, whereupon he said: One of the wives of Allahs Apostle ( صلی اللہ علیہ وسلم ) told me: He (the Holy Prophet) commanded to kill voracious dog, rat, scorpion, kite, crow, and snake (and this is allowed) likewise in prayer.
