وَلَكِنْ رَسُولَ اللَّهِ وَخَاتَمَ النَّبِيِّينَ
Rather, he is the Messenger of Allah and the Seal of the Prophets.
The Messenger’s mission is not restricted to one people or one brief period. His prophethood is universal, and a subsequent claim to prophethood is not accepted. Universality and finality are compatible.
Because the Qur’an and the prophetic teachings remain, a new prophet is not required as a condition of guidance. Reverence for the Prophet entails following his teaching and preserving the finality of his mission.
