About a scorpion it is notable that the Holy prophet, O Allah, grant compensation to Muhammad and his family worthy of their services to Your cause, once extended his hand into a hole for something and a scorpion bit him; and he (the Messenger of Allah) said, ‘May Allah condemn you. You do not distinguish between sinful and sinless ones.’ If a snake attacks you, you can kill it, but if it does not attack, do not attack it. If a biting dog or a beast attacks you [kill them] but if they do not attack you, do not attack them. If it is the treacherous black snake, kill it in all conditions. If it is a crow or al-Hida’at (another kind of crow), shoot them (if they are) on the back of your camel.’”
