Umm al-Mu'mineen Aisha Siddiqa (may Allah be pleased with her) narrates from the Noble Prophet (peace and blessings of Allah be upon him) that the Messenger of Allah (peace and blessings of Allah be upon him) said about the lizard: "It is harmful." But I did not hear him (peace and blessings of Allah be upon him) giving the order to kill it. (However, it should be killed.)
