What the Evidence Establishes
Shahrur describes obedience to the Messenger in his messengerly Sunna as connected obedience. He links it to the rulings of the message contained in the Mother of the Book, as well as to human values, rituals, the theory of limits, and the principle of enjoining what is right and forbidding what is wrong.
He describes this obedience as eternal, universal, and comprehensive, and states that obedience to the Messenger regarding prayer and almsgiving falls within its scope.
Limits of the Claim
The evidence does not define separated obedience, nor does it establish that prophetic obedience is historical or limited. Nor does it provide a criterion for classifying cases between the stations of messengerhood and prophethood.
For conceptual context, see: Muhammad Shahrur: The Messengerly Sunna and the Prophetic Sunna, The Sunna between Messengerhood and Prophethood, and The Station of Prophethood.
