﴿ قَالُوا۟ يَٰصَٰلِحُ قَدْ كُنتَ فِينَا مَرْجُوًّۭا قَبْلَ هَٰذَآ ۖ أَتَنْهَىٰنَآ أَن نَّعْبُدَ مَا يَعْبُدُ ءَابَآؤُنَا وَإِنَّنَا لَفِى شَكٍّۢ مِّمَّا تَدْعُونَآ إِلَيْهِ مُرِيبٍۢ ﴾

“They answered: "O Salih! Great hopes did we place in thee ere this! Wouldst thou forbid us to worship what our forefathers were wont to worship? Because [of this], behold, we are in grave doubt, amounting to suspicion, about [the meaning of] thy call to us!"”

(They said: O Salih! Thou hast been among us hitherto) i.e. before you called us to follow other than the religion of our forefathers (as that wherein our hope was placed) we had hope in you. (Dost thou ask us not to worship what our fathers worshipped) of idols? (Lo! we verily are in grave doubt concerning that to which thou callest us) i.e. your religion.
