Ali 'Imran 3:107

Waamma allatheena ibyaddatwujoohuhum fafee rahmati Allahi hum feeha khalidoon

But as for those whose faces turn white, [they will be] within the mercy of Allāh. They will abide therein eternally.

As for those whose faces turn bright, they will rest in Allah’s mercy. They will live there forever.
