Hazrat Ali (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: Surely, there are lofty chambers in Paradise whose exterior is visible from their interior and their interior is visible from their exterior. Upon this, a Bedouin stood up and said, "O Messenger of Allah (peace and blessings be upon him)! For whom will these lofty chambers be?" The Prophet (peace and blessings be upon him) replied: They will be for the person who speaks pure words, feeds others, spreads greetings of peace, and prays at night when people are asleep.
