مسند أحمد

It was narrated that ‘Ali (رضي الله عنه) said: The Messenger of Allah (ﷺ) said: `In Paradise there are chambers the inside of which can be seen from the outside and the outside can be seen from the inside.` 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.”
