He it is Who has revealed the Book to you; some of its verses are decisive, they are the basis of the Book, and others are allegorical; then as for those in whose hearts there is perversity they follow the part of it which is allegorical, seeking to mislead and seeking to give it (their own) interpretation. but none knows its interpretation except Allah, and those who are firmly rooted in knowledge say: We believe in it, it is all from our Lord; and none do mind except those having understanding.

And they swear by Allah with the strongest of their oaths, that if a sign came to them they would most certainly believe in it. Say: Signs are only with Allah; and what should make you know that when it comes they will not believe?

And when a communication comes to them they say: We will not believe till we are given the like of what Allah's messengers are given. Allah best knows where He places His message. There shall befall those who are guilty humiliation from Allah and severe chastisement because of what they planned.

And they say: Why are not signs sent down upon him from his Lord? Say: The signs are only with Allah, and I am only a plain warner.
