quran:7:184 –

Then do they not give thought? There is in their companion ˹Muhammad˺ no madness. He is not but a clear warner.  

Have they not considered, and so realised that, that there is no madness in their comrade, Muhammad (s)? He is but a clear warner, one whose warning is evident.
القرآن:٧:١٨٤ –

أَوَلَمْ يَتَفَكَّرُوا ۗ مَا بِصَاحِبِهِمْ مِنْ جِنَّةٍ ۚ إِنْ هُوَ إِلَّا نَذِيرٌ مُبِينٌ  

{أو لم يتفكروا} فيعلموا {ما بصاحبهم} محمد ﷺ {من جِنَّة} جنون {إن} ما {هو إلا نذير مبين} بيَّن الإنذار.
