M. H. Shakir, The Holy Quran; Arabic Text and English Translation; Foot-notes by M. H. Shakir (1974)

47. And were it not that there should befall them a disaster for what their hands have sent before, then they should say: Our Lord! why didst Thou not send to us an apostle so that we should have followed Thy communictions and been of the believers!

48. But (now) when the truth has come to them from Us, they say: Why is he not given the like of what was given to Musa? What! did they not disbelieve in what Musa was given before? They say: Two magicians backing up each other; and they say: Surely we are unbelievers in all.

49. Say: Then bring some (other) book from Allah which is a better guide than both of them, (that) I may follow it, if you are truthful.

50. But if they do not answer you, then know that they only follow their low desires; and who is more erring than he who follows his low desires without any guidance from Allah? Surely Allah does not guide the unjust people.

51. And certainly We have made the word to reach them so that they may be mindful.
