Why did Allah write everything in the Preserved Tablet, even though He neither errs nor forgets?

A Muslim believes that Allah is wise in all His actions. Some of His wisdom is known to us, and some He has kept to Himself. Allah's knowledge precedes His inscription of things in the Preserved Tablet (Al-Lawh Al-Mahfuz). His inscription of the destinies of all things therein contains great wisdom, including: affirming Allah's prior knowledge, which neither errs nor forgets; reassuring the servant that what befell him was not meant to miss him, and what missed him was not meant to befall him; demonstrating Allah's effective will, which cannot be repelled; establishing Allah's immense and perfect power; providing an argument against creation; and teaching creation writing and recording. A Muslim should engage in seeking knowledge and contemplating the Qur'an, and should not pay attention to doubts and whispers.
