(71) So did We restore him to his mother, that her eye might be comforted, and that she might not grieve, and that she might know that the promise of Allah is true. But most of them know not.

(72) Is he whom We have promised an excellent promise (Paradise) - which he will find true - like him whom We have made to enjoy the luxuries of the life of (this) world, then on the Day of Resurrection, he will be among those brought up (to be punished in the Hell-fire)?
