How shall Allah guide a people who disbelieved after their believing and (after) they had borne witness that the Messenger was true and clear arguments had come to them; and Allah does not guide the unjust people.

Then if it becomes known that they both have been guilty of a sin, two others shall stand up in their place from among those who have a claim against them, the two nearest in kin; so they two should swear by Allah: Certainly our testimony is truer than the testimony of those two, and we have not exceeded the limit, for then most surely we should be of the unjust.
