(143) They said: Have you come to us to turn us away from what we found our fathers upon, and (that) greatness in the land should be for you two? And we are not going to believe in you.

(144) But none believed in Musa except the offspring of his people, on account of the fear of Firon and their chiefs, lest he should persecute them; and most surely Firon was lofty in the land; and most surely he was of the extravagant.

(145) But if you are in doubt as to what We have revealed to you, ask those who read the Book before you; certainly the truth has come to you from your Lord, therefore you should not be of the disputers.

(146) And you should not be of those who reject the communications of Allah, (for) then you should be one of the losers.

(147) Though every sign should come to them, until they witness the painful chastisement.

(148) And wherefore was there not a town which should believe so that their belief should have profited them but the people of Yunus? When they believed, We removed from them the chastisement of disgrace in this world's life and We gave them provision till a time.

(149) Say: O people! if you are in doubt as to my religion, then (know that) I do not serve those whom you serve besides Allah but I do serve Allah, Who will cause you to die, and I am commanded that I should be of the believers.

(150) And that you should keep your course towards the religion uprightly; and you should not be of the polytheists.
