"But when the truth came to them from Us"—meaning: the Quran—"they said, 'Why has he not been given'"—referring to the Prophet, peace be upon him—"'the like of what was given to Moses?'" That is: Why was the Quran not revealed to him all at once, just as the Torah was revealed to Moses all at once?
Allah said: "But did they not disbelieve in what was given to Moses before?" For the Book of Moses was a proof against them. In the tafsir of al-Hasan: "They said, 'Two sorcerers who support each other'"—meaning Moses and Muhammad; this is according to the tafsir of al-Hasan, and this was the saying of the Arab polytheists—"'And they said, "Indeed, we are in both of them disbelievers"'"—meaning: in both the Torah and the Quran.
