(Ahsaab) 33 : 45
يَا أَيُّهَا النَّبِيُّ إِنَّا أَرْسَلْنَاكَ شَاهِدًا وَمُبَشِّرًا وَنَذِيرًا

Oh you the Prophet! Indeed We have sent you as a witness, a herald of glad tidings, and a warner.

Messenger Muahammed has been deputed to witness a way of life that Lord Allah has satisfied for His entire creatures which is Adhikr whether they like or dislike It. He is also a Herald for the believers who follow that way and a Warner for the Fujjar disbelievers who do not follow that way. Just like Messenger Muhammed, the Wise Reminder Adhikr will also witness in favor of the believers who testify to Adhikr, and will witness against the Fujjar disbelievers as explained in verses 2: 119 and 143. See explanation 3: 91; 11: 17; 16: 89.
