The Prophet ﷺ said, "A tent (in Paradise) is like a hollow pearl which is thirty miles in height and on every corner of the tent the believer will have a family that cannot be seen by the others." (Narrated Abu ʿImran in another narration, "The tent is sixty miles in height.")  

أَنَّ النَّبِيَّ ﷺ قَالَ الْخَيْمَةُ دُرَّةٌ مُجَوَّفَةٌ طُولُهَا فِي السَّمَاءِ ثَلاَثُونَ مِيلاً فِي كُلِّ زَاوِيَةٍ مِنْهَا لِلْمُؤْمِنِ أَهْلٌ لاَ يَرَاهُمُ الآخَرُونَ قَالَ أَبُو عَبْدِ الصَّمَدِ وَالْحَارِثُ بْنُ عُبَيْدٍ عَنْ أَبِي عِمْرَانَ سِتُّونَ مِيلاً
