The Quran is specific when it comes to the consequences of worshiping God and obeying His commands. The following verses from the Quran detail these consequences in both this life and the next life.
Ultimatum 9:71-72
The believing men and women are allies of one another. They advocate righteousness and forbid evil, they observe the Contact Prayers (Salat) and give the obligatory charity (Zakat), and they obey God and His messenger. These will be showered by God's mercy. God is Almighty, Most Wise.
God promises the believing men and the believing women gardens with flowing streams, wherein they abide forever, and magnificent mansions in the gardens of Eden. And God's blessings and approval are even greater. This is the greatest triumph.
Light 24:38
God will certainly reward them for their good works, and will shower them with His grace. God provides for whomever He wills without limits.
Luqmaan 31:2-5
These (letters) constitute proofs of this book of wisdom.
A beacon and a mercy for the righteous.
Who observe the Contact Prayers (Salat), give the obligatory charity (Zakat), and as regards the Hereafter, they are absolutely certain.
They are following the guidance from their Lord, and they are the winners.
The Parties 33:35
The submitting men, the submitting women, the believing men, the believing women, the obedient men, the obedient women, the truthful men, the truthful women, the steadfast men, the steadfast women, the reverent men, the reverent women, the charitable men, the charitable women, the fasting men, the fasting women, the chaste men, the chaste women, and the men who commemorate God frequently, and the commemorating women; God has prepared for them forgiveness and a great recompense.
Thunder 13:18
Those who respond to their Lord deserve the good rewards. As for those who failed to respond to Him, if they possessed everything on earth - even twice as much - they would readily give it up as ransom. They have incurred the worst reckoning, and their final abode is Hell; what a miserable destiny.
Pilgrimage 22:50-51
Those who believe and lead a righteous life have deserved forgiveness and a generous recompense. As for those who strive to challenge our revelations, they incur Hell.
Abraham 14:7
Your Lord has decreed: "The more you thank Me, the more I give you." But if you turn unappreciative, then My retribution is severe.
Abraham 14:2-3
(The path of) God; the One who possesses everything in the heavens and everything on earth. Woe to the disbelievers; they have incurred a terrible retribution.
They are the ones who give priority to this life over the Hereafter, repel from the way of God, and seek to make it crooked; they have gone far astray.
Hood 11:3
"You shall seek your Lord's forgiveness, then repent to Him. He will then bless you generously for a predetermined period, and bestow His grace upon those who deserve it. If you turn away, then I fear for you the retribution of an awesome day."
Hood 11:18-20
Who are more evil than those who fabricate lies about God? They will be presented before their Lord, and the witnesses will say, "These are the ones who lied about their Lord. God's condemnation has befallen the transgressors."
They repel from the way of God and seek to make it crooked, and they are disbelievers in the Hereafter.
These will never escape, nor will they find any lords or masters to help them against God. Retribution will be doubled for them. They have failed to hear, and they have failed to see.
