They were given a word and changed it.
Swapping a simple command for their own version
Those who did wrong among them changed the word that had been told to them. Instead of the humble request for forgiveness, they said something else. So a punishment came from the sky for the wrong they were doing.
Your parent asks you to apologize to your sister. You say sorry you feel that way. The words are close, but the meaning is gone. Changing the instruction while pretending to follow it is still disobedience.
As long as I do something close to what was asked, it counts.
Twisting a clear instruction into my own version is a quiet refusal.
Pick one thing you were asked to do, by Allah or a person you owe. Do it exactly as asked today.
