Surah Al-Anbiyaa, Verse 5
بَلْ قَالُوٓا۟ أَضْغَٰثُ أَحْلَٰمٍۭ بَلِ ٱفْتَرَىٰهُ بَلْ هُوَ شَاعِرٌۭ فَلْيَأْتِنَا بِـَٔايَةٍۢ كَمَآ أُرْسِلَ ٱلْأَوَّلُونَ
Translation — Sahih International
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]."
