On page 31 of The Deliverance From Error, Al-Ghazali gives what he believes to be a proof of prophethood in the world which will satisfy both those who doubt its possibility and those who doubt its actuality.

This trust can be arrived at only by observing the father’s conduct in various situations (The Deliverance From Error, page
