If we want to define the Holy Prophet (peace be upon him and his progeny), we must seek refuge in a logical definition, namely, the science of logic, which is that the holy Prophet of Allah (peace be upon him and his progeny) had all the perfections and was devoid of all imperfections. In other words, He was comprehensively perfect, and no defect and flaw was found in him. This is the definition of the great prophet of Islam.
