And those who have no knowledge say: Why does not Allah speak to us or a sign come to us? Even thus said those before them, the like of what they say; their hearts are all alike. Indeed We have made the communications clear for a people who are sure.

And when Our clear communications are recited to them, those who hope not for Our meeting say: Bring a Quran other than this or change it. Say: It does not beseem me that I should change it of myself; I follow naught but what is revealed to me; surely I fear, if I disobey my Lord, the punishment of a mighty day.

And certainly We gave Musa nine clear signs; so ask the children of Israel. When he came to them, Firon said to him: Most surely I deem you, O Musa, to be a man deprived of reason.

And they say: Why does he not bring to us a sign from his Lord? Has not there come to them a clear evidence of what is m the previous books?

And when Our clear communications are recited to them, their argument is no other than that they say: Bring our fathers (back) if you are truthful.
