Imam Mahdi Will Be The Greatest Human Ever (if He Exists)
There are sayings attributed to the Prophet (pbuh) that Mahdi will fill the earth with justice. That means there will be peace everywhere even if its for a short period of time. I agree with Ghamidi sahab’s view that such a personality is highly unlikely to come but if we assume that he will come in the end times, he should have been greater than all the Prophets.
