Sayyiduna Ali (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: "Indeed, in Paradise there are such lofty chambers that their outer parts can be seen from inside and their inner parts can be seen from outside." Then a Bedouin stood up and asked, "O Messenger of Allah, for whom are these lofty chambers?" The Prophet (peace and blessings be upon him) replied: "They are for the one who speaks pure and sweet words, feeds the hungry, continuously fasts, and offers voluntary prayers at night for the pleasure of Allah while people are asleep."
