Overall meaning : The obedient believers will surely be in gardens of perpetual bliss, while the wicked unbelievers will be in the Fire of Hell, which they will enter to suffer its heat on the Day of Judgment and Recompense, and out of which they will never come out.
What will make you realise what the Day of Judgement and Recompense is, Muhammad?! Again, what will make you realise the true reality of that great, terrible day?!
It is the day when no person will be of any benefit or help to another at all, and all authority on that day is Allah’s alone.
