وَهُمَا مَخْلُوقَتَانِ الْآنَ
Both have already been created.
The Qur'an uses أُعِدَّتْ لِلْمُتَّقِينَ (3:133) and أُعِدَّتْ لِلْكَافِرِينَ (2:24)—prepared for the God-conscious and prepared for unbelievers. This perfect-tense wording is used to argue that the abodes are already prepared.
An abode's existing now is distinct from the future entry of all those destined for it. Preparation does not imply universal present occupancy.
