One day Moses (pbuh) delivered such an impressive sermon that all who heard it was deeply
moved. Someone in the congregation asked: “O Messenger of Allah, is there another man on
earth more learned than you?” Moses replied: “No!”, believing so, as Allah had given him the
power of miracles and honored him with the Torah.
However, Allah revealed to Moses that no man could know all there is to know, nor would one
messenger alone be the custodian of all knowledge. There would always be another who knew
what others did not. Moses asked Allah: “O Allah, where is this man? I would like to meet him
and learn from him.” He also asked for a sign to this person’s identity.
Allah instructed him to take a live fish in a water filled vessel. When the fish disappeared, he
would find the man he sought. Moses set out on his journey, accompanied by a young man who
carried the vessel with the fish. They reached a place where two rivers met and decided to rest
there. Instantly, Moses fell asleep.
