﴿ وَجَعَلْنَا فِيهَا جَنَّٰتٍۢ مِّن نَّخِيلٍۢ وَأَعْنَٰبٍۢ وَفَجَّرْنَا فِيهَا مِنَ ٱلْعُيُونِ ﴾

“and [how] We make gardens of date-palms and vines [grow] thereon, and cause springs to gush [forth] within it,”

And We have placed therein) in the earth (gardens of the date-palm and grapes, and We have caused springs of water to gush forth therein) i.e. rivers therein.
