Quran 2:259 – Are The Bones The Bones Of The Donkey?
Evidently the man had a donkey before he was given death. When he woke up 100 years later, his food was still fresh but bones were all that was left of his donkey. He was asked to look at those bones while God made the donkey come back to life so that he would understand that God can will anything and that His promise of the hereafter is indeed true.
