Immutability - Bible vs Koran

The Bible never change because God never change.

The grass withers, the flower fades, but the word of our God will stand forever. (Isaiah 40:8 ESV)

God is not man, that he should lie, or a son of man, that he should change his mind. Has he said, and will he not do it? Or has he spoken, and will he not fulfill it? (Numbers 23:19 ESV)

if we are faithless, he remains faithful - for he cannot deny himself. (2 Timothy 2:13 ESV)

Allah reserved the right to change his word.
We do not abrogate a verse or cause it to be forgotten except that We bring forth [one] better than it or similar to it. Do you not know that Allah is over all things competent? (2:106 Sahih International version)

Allah eliminates what He wills or confirms, and with Him is the Mother of the Book. (13:39 Sahih International version)

And when We substitute a verse in place of a verse - and Allah 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. (16:101 Sahih International version)
