Granted time is not the same as approval.
Why Iblis was given a reprieve
Allah grants it: you are of those reprieved. Ibn Kathir calls it a reprieve until the Day of Resurrection. The curse from two verses before still stands. Iblis gets time, not approval.
You did something wrong last month and nothing bad happened. No one found out. Life went on. It is easy to read that as permission. A delay is not a verdict.
If nothing bad happened, it must not have been that wrong.
Being given time is a test, not a sign that Allah is pleased.
Think of one thing you got away with, and set it right quietly today if you can.
