Taha 20:133

وَقَالُوا۟ لَوْلَا يَأْتِينَا بِـَٔايَةٍ مِّن رَّبِّهِۦٓ ۚ أَوَلَمْ تَأْتِهِم بَيِّنَةُ مَا فِى ٱلصُّحُفِ ٱلْأُولَىٰ

Waqālū lawlā yatīnā biāyatin min rabbihi awalam tatihim bayyinatu mā fī l-ṣuḥufi l-ūlā

And they say, "Why does he not bring us a sign from his Lord?" Has there not come to them evidence of what was in the former scriptures?
