How does His Excellency [Mahdī (mGehr)] get food, clothes and inhabitance and what are them?
Since we don’t have any narration related to this point, we suppose the Excellency’s food, clothes and inhabitance are natural and usual. It’s because, based on divine tradition, the world of creation has fixed usual laws, except some occasions.
Therefore, the ImÄm (mGehr) has a normal body and uses ordinary food, too. Although, God sometimes sends a heavenly gift to the Excellency, as it was granted to Her Excellency Mary (pbuh) and others.
