Can any Christian show us?

The Quran is from Allah Swt

The revelation of this Book is from Allah, Exalted in Power, Full of Knowledge, ( Surah 40:2)

--------------

We have, without doubt, sent down the Message; and We will assuredly guard it (from corruption). (Surah 15:9)

 No evil ones have brought down this (Revelation): It would neither suit them nor would they be able (to produce it). (Surah 26:210-211)

No falsehood can approach it from before or behind it: It is sent down by One Full of Wisdom, Worthy of all Praise. (Surah 41:42)

And it (the Quran) is not the word of the outcast Shaitan (Satan). (Surah 81:25)

Except whom He has approved of messengers, and indeed, He sends before him [i.e., each messenger] and behind him observers. That he [i.e., Muhammad Pbuh] may know1648 that they have conveyed the messages of their Lord; and He has encompassed whatever is with them and has enumerated all things in number.[ Surah 72:27-28]

This Quran could not have been produced by anyone other than God. In fact, it is a confirmation of what preceded it, and an elaboration of the Book. There is no doubt about it—it is from the Lord of the Universe. [Surah 10:37]

Can our Christian friends show us where Yahweh said the bible is a revelation from him alone and not from Satan?

It's a challenge !!!
