Sayyiduna Abu Musa al-Ash'ari (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: "The Children of Israel wrote a book and began to follow it, and they abandoned the Torah."
Tabarani recorded it in al-Mu'jam al-Awsat; its chain contains a narrator, Muhammad bin Uthman bin Abi Shaybah, who is thiqah (trustworthy), though more than one scholar has declared him da'if (weak).
