The Companies - 39:9 "What do you say to one who prostrates himself at night and stands up and meditates and is conscious of the Hereafter and hopes for the mercy of his Lord? Say, "Are those who know and those who do not know the same?"Only those who have understanding take admonition."
Allah's mercy to the believers 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 Family Of Imran/3:195 "Their Lord answered them: "I will not leave unrewarded any of you who works, whether male or female; you are all equal. Those who emigrated, those who were expelled from their homes, those who were tortured and insulted in My way, those who fought and were killed... I will cover their evil deeds and place them in gardens with rivers flowing in them as a reward from Allah. The best reward is with Allah."

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.
