Shama-il Tirmidhi Chapter 046, Hadith Number 001 (313).

'Umar Radiyallahu 'Anhu says: ''Rasulullah Sallallahu 'Alayhi Wasallam said: 'Do not exceed in praising me as the Christians over-praised 'Esa 'Alayhis Salaam. (That they made him the son of God.) I am a bondsman of Allah, therefore, call me the bondsman of Allah and His Rasul'".

Commentary
Do not praise me in such a manner which is contrary to the bonds-manship of Allah where shirk (partnership) is created with Allah. A bondsman is a bondsman. Do not praise in such a manner that does not befit, and is contrary to the mission of a Rasul and Messenger of Allah.
