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."

Sayyiduna Abu Malik Ash'ari (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: "Indeed, in Paradise there are lofty chambers whose exterior can be seen from their interior and whose interior can be seen from their exterior. Allah Almighty has prepared these chambers for the person who feeds others, speaks gently, fasts regularly, and prays at night while people are asleep."
