It is narrated from Hazrat Samurah (may Allah be pleased with him) that once the Prophet (peace and blessings be upon him) was delivering a sermon when a Bedouin came and started asking questions during the sermon. He said, "O Messenger of Allah, what do you say about the lizard?" The Prophet (peace and blessings be upon him) said, "A community among the Children of Israel had their forms transformed. Now I do not know which animal's forms were transformed."
