The lofty chambers of Paradise

Sayyiduna Abu Malik al-Ash'ari (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: "In Paradise there are upper chambers whose outside can be seen from the inside and whose inside can be seen from the outside. Allah Almighty has prepared them for the one who feeds others, speaks gently, fasts continuously, and prays when people are asleep."
Imam Ahmad recorded it, and its narrators are the narrators of the Sahih, except Abdullah bin Mu'aniq, whom Ibn Hibban declared thiqah (trustworthy).

Sayyiduna Abdullah bin Amr (may Allah be pleased with him) narrates this saying of the Prophet (peace and blessings be upon him): "Indeed, in Paradise there are upper chambers whose outside can be seen from the inside and whose inside can be seen from the outside." Sayyiduna Abu Musa al-Ash'ari (may Allah be pleased with him) asked: "O Messenger of Allah, for whom are they?" The Prophet (peace and blessings be upon him) said: "For the one who speaks gently, feeds others, and spends the night standing before Allah Almighty (in prayer) while people are asleep."
Imam Ahmad recorded it, and its narrators have been declared trustworthy, although there is weakness in some of them. (Allamah al-Haythami says:) I say: Some hadiths on this theme have already passed in the chapter on the virtue of voluntary prayers.
