وَلَا فَخْرَ
Not as an expression of boasting.
The Prophet's description of his rank identifies a divine gift and mission; it is not self-exaltation. Disclosing a responsibility or bestowed distinction is different from looking down upon others out of arrogance. The second is blameworthy, while the first can be a truthful announcement.
The words “without boasting” do not cancel the stated precedence, for that would empty the first clause of its meaning. Nor may the truthful statement of a divinely given rank be equated with pride without evidence.
