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)
عَنْ رَسُولِ اللَّهِ ﷺ قَالَ «إِنَّ فِي الْجَنَّةِ غُرَفًا يُرَى ظَاهِرُهَا مِنْ بَاطِنِهَا وَبَاطِنُهَا مِنْ ظَاهِرِهَا» فَقَالَ أَبُو مَالِكٍ الْأَشْعَرِيُّ لِمَنْ يَا رَسُولَ اللَّهِ؟ قَالَ «لِمَنْ أَطَابَ الْكَلَامَ وَأَطْعَمَ الطَّعَامَ وَبَاتَ قَائِمًا وَالنَّاسُ نِيَامٌ»
