أَرْسَلَهُ بِحُجَّة كَافِيَة، وَمَوْعِظَة شَافِية، وَدَعْوَة مُتَلافِيَة . أَظْهَرَ بِهِ الشَّرائِعَ الْـمَجْهُولَةَ، وَقَمَعَ بِهِ الْبِدَعَ الْمَدْخُولَةَ، وَبَيَّنَ بِهِ الاْحْكَامَ الْمَفْصُولَةَ. فَـ﴿مَن يَبْتَغِ غَيْرَ الْإِسْلَامِ دِينًا﴾ تَتَحَقَّقْ شِقْوَتُهُ، وَتَنْفَصِمْ عُرْوَتُهُ، وَتَعْظُمْ كَبْوَتُهُ، وَيَكُنْ مَآبُهُ إلَى الْحُزْنِ الطَّوِيلِ وَالْعَذَابِ الْوَبيلِ.
Allāh sent him with a sufficing plea, a convincing discourse and a rectifying annoucement. Through him Allāh disclosed the ways that had been forsaken, and destroyed the innovations that had been introduced. Through him He explained the detailed commands. Now, whoever adopts a religion other than Islam, his misery is definite, his stick (of support) will be cracked, his fate will be serious, his end will be long grief and distressing punishment.
