Narrated by Sahl b. Sa'd
Sahl b. Sa'd reported Allah's Messenger (may peace be upon him) as saying: The inmates of Paradise will look to the upper apartment of Paradise as you see the planets in the sky. I narrated this hadith to Nu'man b. Abi 'Ayyash and he said: I heard Abu Sa'id al-Khudri as saying: As you see the shining planets in the eastern and western (sides of) horizon.

Narrated by Abu Sa'id al-Khudri
Abu Sa'id al-Khudri reported Allah's Messenger (may peace be upon him) as saying: The inmates of Paradise would see the inmates of the apartment over them just as you see the shining planets which remain in the eastern and the western horizon because of the superiority some have over others. They said: Allah's Messenger, would in these abodes of Apostles others besides them not be able to reach? He said: Yes, they will, by Him, in Whose hand is my life, those who believe in God and acknowledge the Truth, will reach them.
