Al-Anbiyaa · verse 5 of 112
21:5
بَلْ قَالُوٓا۟ أَضْغَٰثُ أَحْلَٰمٍۭ بَلِ ٱفْتَرَىٰهُ بَلْ هُوَ شَاعِرٌۭ فَلْيَأْتِنَا بِـَٔايَةٍۢ كَمَآ أُرْسِلَ ٱلْأَوَّلُونَ ﴿5﴾
Nay, say they, (these are but) muddled dreams; nay, he hath but invented it; nay, he is but a poet. Let him bring us a portent even as those of old (who were Allah's messengers) were sent (with portents).
