The words of the Lord are perfect in truth
and justice;
there is NONE who can change His words.
He both heareth and knoweth.
-- Sura 6:115
None can change the words of God;
-- Sura 6:34
There is no changing the words of God;
that is the mighty triumph.
-- Sura 10:65
And for whatever verse we abrogate and cast into
oblivion
We bring a better or the like of it;
knowest thou not that God is powerful over everything?
-- Sura 2:106
And when We exchange a verse in place of another verse
--
and God knows very well what He is sending down --
they say, 'Thou art a mere forger!'
Nay, but the most of them have no knowledge.
-- Sura 16:101
NONE can change the words of God. But God DOES EXCHANGE
one verse for another verse. And he does so through his
messengers like Jesus [who changed some rules given through
Moses] and like Muhammad who gives rules different again
from Moses and Jesus.
