Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) narrates: When this verse was revealed: "Indeed, this (teaching, or statement) is in the earlier scriptures, the scriptures of Ibrahim and Musa," the Prophet (peace and blessings be upon him) said: "All of this (the narrator is unsure; perhaps the words are:) this is in the scriptures of Ibrahim and Musa."
Al-Bazzar recorded it; its chain contains a narrator, Ata' bin al-Sa'ib, whose memory became confused (ikhtilat), and the rest of its narrators are the narrators of the Sahih.
