I give them time, and My plan is firm.
Delay is not escape
Following the last verse, Allah says He gives them time, and His plan is firm. Ibn Kathir explains it as prolonging what they are in, while the plan stays strong and perfect.
You did something wrong years ago and nothing came of it. It is easy to forget it, as if it never happened. The time you have been given is not proof you got away. It is the space to turn back.
Nothing bad happened, so it must not have mattered.
Allah's respite is time given to repent, not proof I escaped.
Think of an old wrong you have never repented from. Repent today, and fix what you can.
