Ibn al-Qayyim, however, said: "To waive shufʿah before the sale is simply the surrender of a right whose holder has consented to relinquish it; the right was his, and he has abandoned it. Therefore, if he authorizes the sale or declares, ‘I have no interest in it,’ he no longer has any claim to shufʿah after the sale is completed. Such is the judgment required by the Sacred Law; nothing at all contradicts it, and it is the definitively correct view."
He further wrote in the marginal notes to al-Muqniʿ: "This is the truth about which there is no doubt."
