Some of these sections are found in the Torah that is now in their possession, some in the prophecies of Isaiah, and some in the prophecies of others. “The first Torah” (1) is broader than the particular Torah known today. Allah—glorified be He—had written for Moses on the tablets an admonition about everything and a detailed clarification of every matter; but when he broke them, much of that knowledge was removed while a great deal of good remained.
