Sayyidina Ali (RA) reported that Allah’s Messenger (SAW) said, “In Paradise, there are upper chambers their exterior can be seen from their interior, and their interior from their exterior side.” A villager stood up and asked, “For whom are they, O Messenger of Allah!” He said, “For those who speak a good word, feed the food, fast often, and pray by night when people are asleep.”
[Ahmed 1337]
