الانبياۤء — Al-Anbiya' Ayat 5
بَلْ قَالُوْٓا اَضْغَاثُ اَحْلَامٍۢ بَلِ افْتَرٰىهُ بَلْ هُوَ شَاعِرٌۚ فَلْيَأْتِنَا بِاٰيَةٍ كَمَآ اُرْسِلَ الْاَوَّلُوْنَ
Bal qālū aḍgāṡu aḥlāmim baliftarāhu bal huwa syā‘ir(un), falya'tinā bi'āyatin kamā ursilal-awwalūn(a).
"But they say, "[The revelation is but] a mixture of false dreams; rather, he has invented it; rather, he is a poet. So let him bring us a sign just as the previous [messengers] were sent [with miracles].""
