The Prostration - 32:28
"They challenge, "When will that victory come, if you are truthful?"
Victory for the believers:
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 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.
The Companies/39:73
"And those who count and listen to their Lord will be taken to Paradise in multitudes. When they arrive there, its gates will open and its guards will say to them, "Peace be upon you; you have won. Enter therein to abide therein for ever."
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.
