بَلْ قَالُوا أَضْغَاثُ أَحْلَامٍ بَلِ افْتَرَاهُ بَلْ هُوَ شَاعِرٌ فَلْيَأْتِنَا بِآيَةٍ كَمَا أُرْسِلَ الْأَوَّلُونَ ٥

But (the wrongdoers go so far as to) say: ‘This (Qur’an) comprises (things seen in) confused dreams. Nay! He has invented it (himself). Nay, he is (in fact) a poet. (If he is a true Prophet,) let him (also) bring us some sign as the former (Prophets) were sent (with signs).’ (21:5)
