The Cattle - 6:157
"Nor can you say, "If the Book had been sent down to us, we would have been on a more right path than them". There has come to you a proof from your Lord, a guidance and a mercy. Who is more unjust than he who denies the signs of Allah and turns away from them? We will punish those who turn away from Our Verses with the worst of torment for their turning away."
God's mercy on the Day of Resurrection:
The Family Of Imran/3:185
Everyone will taste death. On the Day of Resurrection your rewards will be given to you in full. And whoever is rescued from the Fire and admitted to Paradise, he is victorious. The life of this world is but a deceitful pleasure.
The Cattle/6:16
Whoever is turned away from torment on that Day, (God) has mercy on him. That is the greatest victory.
Mary/19:68
By your Lord, We shall gather them and the devils. Then We will bring them around Hell. On their knees.
Mary/19:69
Then We will weed out from every group those who have gone far in transgression against the Most Merciful.
Mary/19:70
Surely We know well who is most deserving of burning therein.
Mary/19:71
There is none of you who will not come therein; this is a sure decision of your Lord.
Mary/19:72
Then We will save the righteous. And We will leave the wrongdoers on their knees therein.
The Forgiver/40:9
Protect them from evil. Whomever You protect from evil on that Day, You will have mercy on them. This is the great victory.
The Kneeling/45:30
As for those who believe and do righteous deeds, their Lord will admit them into His mercy. That is the clear victory.
