Say: "Bring forward your witnesses who could testify that God has made unlawful (what you claim to be forbidden.)" Then if they bear witness (falsely), do not bear witness with them, and do not follow the lusts and fancies of those who deny Our signs and Revelations, who do not believe in the Hereafter, and who (as the main source of their unbelief in other essentials of faith) ascribe equals to their Lord.
