2:41And believe in what I revealed, confirming what is with you; and do not be the first to deny it; and do not exchange My revelations for a small price; and be conscious of Me.

2:79So woe to those who write the Scripture with their own hands, and then say, “This is from God,” that they may exchange it for a little price. Woe to them for what their hands have written, and woe to them for what they earn.

2:174Those who conceal what God revealed in the Book, and exchange it for a small price—those swallow nothing but fire into their bellies. And God will not speak to them on the Day of Resurrection, nor will He purify them, and they will have a painful punishment.
