Al-Mu'minun - 23:25

إِنْ هُوَ إِلَّا رَجُلٌ بِهِ جِنَّةٌ فَتَرَبَّصُوا بِهِ حَتَّى حِينٍ
[23:25]
He is only a madman, so bear with him for a time.
(And some said): "He is only a man possessed: wait (and have patience) with him for a time."
He is only a man in whom is a madness, so watch him for a while.
