Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: "It is permissible to kill five animals within the boundaries of the Haram: the snake, the scorpion, the mouse, the kite, and the biting dog." Imam Abu Bakr (may Allah have mercy on him) says that Imam Muhammad bin Yahya, while explaining the biting dog, mentioned the snake; it is possible that this was a slip of the tongue, because there is no connection between the snake and the dog, nor is the word 'dog' used for a snake. However, the word 'dog' is applied to the leopard and the wolf. In the narration of Hatim bin Isma'il, this clarification exists that the Noble Prophet (peace and blessings be upon him) differentiated between the snake and the biting dog. Therefore, how is it possible that in this narration, the biting dog refers to the snake, as the word 'dog' is not used for the snake.
