How do we reconcile your statement that a day in Paradise is not like a day in this world, with the narrations indicating that the people of Paradise will enjoy delights for tens of years, and with their weekly visit to Allah every Friday?

In Paradise, there is neither night nor day, neither sun nor moon; rather, there is perpetual light. The duration of night is known by the lowering of veils and the closing of doors, and the duration of day by the raising of veils and the opening of doors. The mention of morning and evening in the Quran, as in His Almighty saying: "And for them therein is their provision morning and evening" (Qur’an 19:62), refers to the duration of these two times as they are known in this world, not their actual existence. Their mention could be to indicate perpetuity or to encourage. Similarly, the believers' vision of their Lord on Friday means in the measure of every week, because Paradise has no sun, night, or day, and its time is known by the change of lights. As for the saying that a man will recline for forty or seventy years without changing, it is a weak hadith. Even if it were authentic, it falls under the unseen, and matters of the Hereafter are not to be measured against this world.
