What is your opinion regarding someone who believes in the ability of the righteous to see into the Preserved Tablet and to know the Unseen?

No one is permitted to believe that a righteous person can look into the Preserved Tablet (al-Lawh al-Mahfuz), as this pertains to the Unseen, which can only be established through a textual proof, and there is no indication that anyone has been granted such a ability. Allah informs His prophets of some aspects of the Unseen through revelation, as a means of supporting them. A saint (wali) may also be informed of a matter from the Unseen through inspiration (ilham), as happened with Umar ibn al-Khattab and Sariya. However, this does not mean that he looked into the Preserved Tablet. A believer should not delve into the specifics of how inspiration and unveiling occur.
