So Lord Allah shielded them from that Day’s evil and they can meet Brightness and Happiness.
The Impartial Allah will not cause anyone to enter the Paradise or the Hell. But He has taught each and every one Adhikr after the creation in the Paradise. It is the Food, Cloth and Sight of human soul. It is also the Shield and Safeguard against all disasters as well as Hellfire. Hence, the believers should utilize It as the Shield and Safeguard in this worldly life. Whereas the hypocrites and their blind followers will reject It and thus they are the fuel of Hell from mankind. They are the worst creatures in the land as explained in the verse 98: 6. Since they will be veiled from their Lord as mentioned the verse 83: 15, they will not see their Lord forever.
The believer and heedful will see their Lord brightly. They are those who utilize Adhikr as the Insight in this world. At the time of death they will look at their Lord brightly and pleasantly is told in the verses 75: 22-23. Whereas disbeliever will see Satan gloomily is told in the verse 75: 24. See the explanation 74: 53-56; 88: 2-16 and 98: 7-8 in the Exalted Book.
