The Prophet ﷺ said, "The people of Paradise will see the lofty chambers in Paradise just as you see the stars in the sky."
عن النبي ﷺ قال: إن أهل الجنة ليتراءون الغرف في الجنة، كما تتراءون الكوكب في السماء.
Bukhari narrated it in the Book of Softening of Hearts (6555), and Muslim in the Book of Paradise, its Description of Bliss and Its People (2830), both through the route of Abu Hazim, from Sahl bin Saad, who mentioned it.
