Overall meaning : The unbelievers mocking say to one another, ‘Shall we show you a man who claims that when you have been reduced to dust after your death you will be raised to life again?! Has he invented a lie about Allah, or is he mad?!’
No indeed! The fact is that those who do not believe in the afterlife are doomed to punishment and they have strayed far away from the truth.
Do these unbelievers not see that the sky and the earth are extended in front of them and behind them and that they are surrounded by them from all sides? If We willed, We could destroy them by causing the earth to swallow them up or letting fragments of the sky fall down upon them. Surely there is a sign in this for every servant who repents and turns to Allah.
