Surah 6

Surah 6:92

"This is a Book: We have sent it down, blessed, confirming that which was before it. And (We sent it down) so that you may warn the Mother of Towns and those around it. Those who believe in the Hereafter believe in it, and they keep guard over their prayers."

6.92 – This is a Book: We have sent it down, blessed, confirming that which was before it
After mentioning the “Book which Moses brought,” the Quran claims that the present recitation is also revealed by Allah. See this “self-referential” style of verse in “Different Kinds of Literature” in the general introduction.
The Quran frequently states that its contents confirm (muṣaddiq) what came before it – in this case apparently the Torah. For an analysis of the Quran’s claim of confirmation, see 46.12.
