Explanation:

The mud and the pot are taken as similes for God and the world during the creation process. The party supporting the existence of a separate pot is mocked at by the other party since the first party is unable to bring water with the pot from which the mud is withdrawn by the second party. The reverse mocking also takes place because the second party, which believes only in the existence of the mud, also cannot bring water with the help of a lump of mud.
