The dual mission of the Prophet

وَمَآ أَرْسَلْنَـٰكَ إِلَّا مُبَشِّرًا وَنَذِيرًا

And We have not sent you, [O Muḥammad], except as a bringer of good tidings and a warner.

إِنَّآ أَرْسَلْنَـٰكَ بِٱلْحَقِّ بَشِيرًا وَنَذِيرًا ۚ وَإِن مِّنْ أُمَّةٍ إِلَّا خَلَا فِيهَا نَذِيرٌ

Indeed, We have sent you with the truth as a bringer of good tidings and a warner. And there was no nation but that there had passed within it a warner.
