قالوا أَجِئتَنا لِنَعبُدَ اللَّهَ وَحدَهُ وَنَذَرَ ما كانَ يَعبُدُ آباؤُنا ۖ فَأتِنا بِما تَعِدُنا إِن كُنتَ مِنَ الصّادِقينَ

They said, "Have you come to us that we should worship Allah alone and leave what our fathers have worshipped? Then bring us what you promise us, if you should be of the truthful."
