This notion is false, for although the existence of things is an illusion compared to the existence of God, yet in the contingent world it is established, proven, and undeniable. For example, the existence of the mineral is non-existence compared to that of man- since man's body becomes mineral when he physically dies- but the mineral indeed exists within the mineral realm. It is therefore clear that dust is non-existent or has an illusory existence compared to that of man, but that within the mineral realm it exists (79:2)
