The Messenger of Allah ﷺ said: ʿIn Paradise there are chambers the inside of which can be seen from the outside and the outside can be seen from the inside.ʿ A Bedouin said: O Messenger of Allah ﷺ, who are they for? He said: “For the one who speaks kind words, feeds people and prays to Allah at night when people are asleep.” (Using translation from Aḥmad 1338)

قَالَ رَسُولُ اللَّهِ ﷺ «إِنَّ فِي الْجَنَّةِ لَغُرَفًا يُرَى بَاطِنُهَا مِنْ ظَاهِرِهَا وَظَاهِرُهَا مِنْ بَاطِنِهَا» فَقَالَ أَعْرَابِيٌّ لِمَنْ هِيَ يَا رَسُولَ اللَّهِ؟ قَالَ «لِمَنْ أَطَابَ الْكَلَامَ وَأَطْعَمَ الطَّعَامَ وَأَدَامَ الصِّيَامَ وَصَلَّى لِلَّهِ ﷻ بِاللَّيْلِ وَالنَّاسُ نِيَامٌ»
