Say, [O Muhammad], "Bring forward your witnesses who will testify that Allah has prohibited this." And if they testify, do not testify with them. And do not follow the desires of those who deny Our verses and those who do not believe in the Hereafter, while they equate [others] with their Lord.

Tafsir of Verse 150
Say: 'Produce your witnesses, those who testify God has forbidden this.' Then if they testify, bear not witness with them; and do not thou follow the caprices of those who cried lies to Our signs, and who believe not in the world to come, and ascribe equals to their Lord.
Say: "Bring forward your witnesses to prove that Allah did forbid so and so." If they bring such witnesses, be not thou amongst them: Nor follow thou the vain desires of such as treat our signs as falsehoods, and such as believe not in the Hereafter: for they hold others as equal with their Guardian-Lord.
