“I, YHVH, do not change.”
“I will send my messenger, who will prepare the way before me. Then suddenly the Lord you are seeking will come to his temple; the messenger of the covenant, whom you desire, will come,” says YHVH Tseva’oth. But who can endure the day of his coming? Who can stand when he appears? For he will be like a refiner’s fire or a launderer’s soap. He will sit as a refiner and purifier of silver; he will purify the Levites and refine them like gold and silver.
Then YHVH will have men who will bring offerings in righteousness, and the offerings of Judah and Jerusalem will be acceptable to YHVH, as in days gone by, as in former years. “So I will come to put you on trial. I will be quick to testify against sorcerers, adulterers and perjurers, against those who defraud laborers of their wages, who oppress the widows and the fatherless, and deprive the foreigners among you of justice, but do not fear me,” says the YHVH Tseva’oth. “I YHVH do not change.
“So you, the descendants of Jacob, are not destroyed. Ever since the time of your ancestors you have turned away from my decrees and have not kept them. Return to me, and I will return to you,” says YHVH Tseva’oth. “But you ask, ‘How are we to return?’ Malachi 3:1-7
Wisdom in the WORD 
The concept of change is very clear as a philosophical concept. Change is known to be a constant in all of existence. Change is a fundamental reality. Now, we agree that the Creator does not change in essence but in a strict sense even action can be said to involve change, though we would agree, change in other things but not change in the essence of the Creator.
Now, that being said, here we have something different. This fundamental acceptance in Islam that the Qur’an itself does contain verses which were abrogated makes it quite obvious that change is a fundamental facet in its own formation. We cannot claim something does not change and also claim that it has things in it which have been overruled. We simply cannot have it both ways. Now, we can certainly have something which contains things that are overruled but it defies the most basic level of knowledge to claim that a word means both itself and its contradictory opposite.
Bad could mean cool if that is an accepted meaning as some people in the 80s thought they were.
Unchanged has never meant changed. By definition. Abrogation can never mean pristine & unchanged. By definition.
So by definition, the Qur’an has changed. Change is inherent within its very own pages.
