Does Allah's knowledge of everything, including the unseen, extend infinitely, or is it limited to a specific time period, such as a thousand years?

Allah's knowledge encompasses the past, present, and future, including the details of the affairs and desires of the people of Paradise. This is indicated by the generality of His sayings: (Indeed, Allah is Knowing of all things) and (And know that Allah is Knowing of all things) and (Does He who created not know, while He is the Subtle, the Acquainted?) and (He said, "My Lord knows [every] statement in the heaven and earth, and He is the Hearing, the Knowing"). Imam An-Nawawi affirms that Allah knows what was, what will be, and what would have been if it had been. Sheikh Ibn 'Uthaymeen clarified that Allah's knowledge includes His actions and the actions of His servants, encompassing universals and particulars, what has occurred and what will occur, and what is obligatory, possible, and impossible.
