Abu Hurairah narrated that the Prophet (s.a.w) said:
"Indeed, the people of Paradise shall see the upper chamber like they see the eastern star, or the western star, disappearing in the far edge of the sky, or ascending due to the differences in levels." They said: "Are those the Prophets?" He said: "Yes. By the One in Whose Hand is my soul, and groups who had faith in Allah and His Messenger, and believed in the Messengers."
