Sahih Muslim Book 42, Hadith Number 7142.

Chapter : It is prohibited to praise anyone so much that there may be fear of his being intoxicated because of that.

Abu Ma’mar reported that a person lauded a ruler amongst the rulers and Miqdad began to throw dust upon him and he said: Allah’s Messenger (may peace be upon him) commanded us that we should throw dust upon the faces of those who shower too much praise.
