Musannaf Ibn Abi Shaybah 36678 — Reports on the description

It is narrated from Sayyiduna Ali (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "In Paradise there are rooms whose inside can be seen from the outside and whose outside can be seen from the inside." A Bedouin, on hearing this, stood up and said: "O Messenger of Allah (peace and blessings be upon him)! For whom are those rooms?" He said: "Those rooms are for one who speaks good words (speaks the truth), feeds the hungry, spreads the greeting of peace, and prays at night while people are resting."
