Al-A'raf - 7:184

أَوَلَمْ يَتَفَكَّرُواْ مَا بِصَاحِبِهِم مِّن جِنَّةٍ إِنْ هُوَ إِلاَّ نَذِيرٌ مُّبِينٌ
[7:184]
Do they not reflect that their companion has not unsoundness in mind; he is only a plain warner.
Do they not reflect? Their companion is not seized with madness: he is but a perspicuous warner.
Have they not bethought them (that) there is no madness in their comrade? He is but a plain warner.
