But when Isa perceived unbelief on their part, he said Who will be my helpers in Allah's way? The disciples said: We are helpers (in the way) of Allah: We believe in Allah and bear witness that we are submitting ones.

Say: O followers of the Book! why do you disbelieve in the communications of Allah? And Allah is a witness of what you do.

Who is then more unjust than he who forges a lie against Allah or rejects His communications? (As for) those, their portion of the Book shall reach them, until when Our messengers come to them causing them to die, they shall say: Where is that which you used to call upon besides Allah? They would say: They are gone away from us; and they shall bear witness against themselves that they were unbelievers

And those who disbelieve say: You are not a messenger. Say: Allah is sufficient as a witness between me and you and whoever has knowledge of the Book.

Say: Allah is sufficient as a witness between me and you; He knows what is in the heavens and the earth. And (as for) those who believe in the falsehood and disbelieve in Allah, these it is that are the losers.

Say: Have you considered if it is from Allah, and you disbelieve in it, and a witness from among the children of Israel has borne witness of one like it, so he believed, while you are big with pride; surely Allah does not guide the unjust people.

Have you not seen those who have become hypocrites? They say to those of their brethren who disbelieve from among the followers of the Book: If you are driven forth, we shall certainly go forth with you, and we will never obey any one concerning you, and if you are fought against, we will certainly help you, and Allah bears witness that they are most surely liars.
