والرسول إنسان بعثه الله تعالى إلى الخلق لتبليغ الأحكام
A messenger is a human being whom God sends to creation to communicate divine rulings.
Baʿth means divine appointment; tablīgh means conveying the entrusted message; and aḥkām refers to the normative guidance communicated through revelation. The messenger is not merely a moral philosopher offering personal insights. He delivers a message under a divine commission.
His human presence allows people to hear the message, understand its content and examine evidence offered for the claimed commission.
