Quran

There will not be a wish that Allah does not grant them even though they are aware of His overall bounty. Allah, the Almighty, is not obligated to do anything for anyone, and no one reveres Him His true reverence. If He were to take people to task for their wrongdoing, they would be doomed. The greatest blessing he bestowed upon them was making them the followers of His Messenger, and that was the cause of all the good they receive. Al-Biqai: 22/198.
