قَالُوا۟ يَٰصَٰلِحُ قَدْ كُنتَ فِينَا مَرْجُوًّۭا قَبْلَ هَٰذَآ ۖ أَتَنْهَىٰنَآ أَن نَّعْبُدَ مَا يَعْبُدُ ءَابَآؤُنَا وَإِنَّنَا لَفِى شَكٍّۢ مِّمَّا تَدْعُونَآ إِلَيْهِ مُرِيبٍۢ
They said: O Salih! Thou hast been among us hitherto as that wherein our hope was placed. Dost thou ask us not to worship what our fathers worshipped? Lo! we verily are in grave doubt concerning that to which thou callest us.
