What is God Almighty's wisdom in the food of our master Uzair remaining unchanged, while his body and donkey changed?

This story summarizes Allah Almighty's power and magnificent planning, for He brought a man and his donkey back to life after one hundred years of death, while preserving his food and drink fresh without any change. This is not due to nature but to Allah's will, so that the man might be a sign for people of Allah's power to grant life and cause death.
