Abd al-Malik bin Umayr narrates from Sayyiduna Jabir bin Samurah (may Allah be pleased with him) that he said: A Bedouin came to the Messenger of Allah (peace and blessings be upon him) and said: "O Messenger of Allah, what do you say about the dabb (spiny-tailed lizard)?" He said: "A nation from the Children of Israel was transformed, and I do not know into which animal it was transformed. I neither command it nor forbid it."
