Then do they not give thought? There is in their companion [Muhammad] no madness. He is not but a clear warner.
The Saheeh International Quran Translation
أَوَلَمْ يَتَفَكَّرُوا۟ مَا بِصَاحِبِهِم مِّن جِنَّةٍ إِنْ هُوَ إِلَّا نَذِيرٌ مُّبِينٌThen do they not give thought? There is in their companion [Muhammad] no madness. He is not but a clear warner.
