Quran 34:28 · Saba

Every prophet did missionary work directly with his people (community). That alone was practicable. Similarly, the Prophet Muhammad also became the direct dispenser of good news (mubashshir) and a direct warner (munzir) for his own people (

6:92

). But, since the institution of prophethood ended with him, he is now, by order, mubashshir and munzir for all the nations in the world. Just as he discharged both these functions in relation to his first addressees (in his own times), so in the same way, his followers as deputies had to discharge these functions in relation to all other addressees in later periods. This will be treated as continuity of his prophetic mission. The missionary work done by him during his life-time is directly within the ambit of his prophetic functions, while the work done after his life in this world, will be indirectly so. The mission of a prophet is always to convey the message of God. Thereafter, the reward or punishment, according to the response of the people, is for God to decide—in this world as well as in the Hereafter.
