قَالُوٓا۟ أَجِئْتَنَا لِنَعْبُدَ ٱللَّهَ وَحْدَهُۥ وَنَذَرَ مَا كَانَ يَعْبُدُ ءَابَآؤُنَا ۖ فَأْتِنَا بِمَا تَعِدُنَآ إِن كُنتَ مِنَ ٱلصَّٰدِقِينَ
They said: Hast come unto us that we should serve Allah alone, and forsake what our fathers worshipped? Then bring upon us that wherewith thou threatenest us if thou art of the truthful!
