Surah 20:133
"They say, ‘If only he would bring us a sign from his Lord.’ Has there not come to them a clear sign (of) what was in the former pages?"
20.133 – Has there not come to them a clear sign (of) what was in the former pages?
The expression “former pages” ( al-ṣuḥuf al-ūlā ) may refer to earlier scriptures and, if so, indicates a favorable attitude toward pre-Islamic scriptures.
