وَأُرْسِلْتُ إِلَى الْخَلْقِ كَافَّةً.
And I have been sent to the whole creation. (Ṣaḥīḥ Muslim)
Kāffatan conveys comprehensive inclusion. The report confirms the broad scope of the Prophet’s mission.
The Qur’anic declaration and this Prophetic statement establish one principle: the message is not restricted to one locality or only its original audience.
