Which Garden (Jannah) is the one that Adam resided in?

Imām Ibn al-Jawzī (d. 597/1201) summarized the scholars' opinions in his book "Zād al-Masīr" as follows:

1. The Garden of ʿAdn (on earth).
2. The Eternal Garden (which we will enter in the Hereafter). (Ed: this is by far the most common understanding among the scholars.)
