“You’re Not God to Judge Me”
If “you’re not God to judge me” simply meant “you cannot decide my eternal fate, for only God alone can,” then that is not problematic. However, this expression is growingly transforming to mean, “you’re not God to tell me I am doing something wrong.” In other words, human beings are not warranted to point out that others are behaving sinfully according to the guidelines of God Himself.
It seems like some Muslims temporarily overlook what a Muslim entails being. These same “mind your own business” folks will censure others who act immorally in public (e.g., being obscene, rude to elders, abusive to their children, etc.); thus, the principle of calling out the immoral actions of individuals is one which they allow. However, they seemingly forget which moral code they should abide by. Instead, they arbitrarily restrict themselves to acts they feel warrant rebuking/warning/advising, rather than referring back to the divine guidance Muslims must submit to.
