﴿ أَوْ يُصْبِحَ مَآؤُهَا غَوْرًۭا فَلَن تَسْتَطِيعَ لَهُۥ طَلَبًۭا ﴾

“or its water sinks deep into the ground, so that thou wilt never be able to find it again!"”

(Or some morning the water thereof) the water of the garden (will be lost in the earth) will sink in the earth, out of reach (so that thou canst not make search for it) so that you cannot access it.
