Quran 2:78.
And among them are illiterates who know nothing about the scriptures except lies, and "therefore" they "willingly" conjecture.
Quran 2:79.
So woe to those who distort the scriptures with their own hands and then say, "It is from God" - looking for a fleeting gain! So woe to them for what their hands have written, and woe to them for what they have earned.
