As I was reciting Chapters 15 and 16 tonight. I noticed how God calls the Quran the Remembrance,
{15:9} Verily, [it is] We [who] have been sending down the Reminder and verily, [it is] We [who] are indeed guarding it. And that got me thinking about
{16:44} [We sent them] with clear proofs and written ordinances. And We sent down to you the Remembrance so that you may make clear to the people what has been sent down to them and that they might give thought. It must mean the Quran too, but what does the verse refer to when it says, "
So that you may make clear to the people what has been sent down to them"?
I have read many interpretations of that clause. Some said that it refers to the Quran and that the Remembrance is the Hadeeth. Those scholars believe that the Hadeeth too was preserved by God and was sent down by God. If that interpretation is true, then the folks who believe that the Sunna can abrogate the Quran may have an argument. But the majority do not share that interpretation.
I only had to notice the verse immediately before it to understand what the clause means,
{16:43} And We did not send before you except men to whom We revealed [Our message]. So ask the people of the Remembrance if you do not know. The clause means prior revelations! The Quran was sent down to explain to all people, especially the People of the Book, what they have differed on, which happened because they edited the Scriptures.
This view is supported later in
And all that is
a prelude, I think, to the substitution verse, following in the same Chapter and often quoted as evidence for abrogation,
{16:101} And when We substitute a sign in place of a sign - and God is most knowing of what He sends down - they say, "You, [O Muhammad], are but an inventor [of lies]." But most of them do not know. It's about the sign of the Quran replacing the signs of the Torah and Gospel in order to confirm what is original in them and correct what was edited or added to them. Confirmation and correction is what naskh is.
This become even clearer when one notices that prior scriptures, in their original form, have been called the Remembrance as well, e.g.,
{21:105} And We wrote in the Psalms, after the Remembrance, that Our righteous worshipers inherit the earth. Which most likely refers to the Torah.
