(Al-Ahraf) 7 : 70
قَالُوا أَجِئْتَنَا لِنَعْبُدَ اللَّهَ وَحْدَهُ وَنَذَرَ مَا كَانَ يَعْبُدُ آبَاؤُنَا ۖ فَأْتِنَا بِمَا تَعِدُنَا إِنْ كُنْتَ مِنَ الصَّادِقِينَ
They asked: "Have you come to us commanding us to serve Lord Allah alone, and to avoid whatever our forefathers have been serving? Then you bring us whatever you are promising us if you are among the truthful".
