Change for the sake of change isn’t ‘change’, and change which erodes your established principles is not change based on knowledge; but rather data & unprocessed information.
True knowledge does not ‘change’ the constants (correctly established principles) of a sincere person; but rather increases a person in faith, firmness to the truth, and faithfulness to Allah Almighty (positive change).
About this Allah Almighty says:
“And so those who were given knowledge may know that it is the truth from your Lord and [therefore] believe in it, and their hearts humbly submit to it. And indeed is Allah the Guide of those who have believed to a straight path”.
As for unprocessed new learnings (data & information) that in turn erodes a person’s correctly established principles; then this learning, in my humble view, is a fitnah and not a blessing.
There is a difference between knowledge that changes the human condition for the better, and unprocessed information that effects change, but for the worse.
