Al-Hasan narrated that:
Abu Hurairah said: “Once when the Prophet of Allah was sitting with his Companions, a cloud came above them, so the Prophet of Allah said: ‘Do you know what this is?’ They said: ‘Allah and His Messenger know better.’ He said: ‘These are the clouds that are to drench the earth, which Allah [Blessed and Most High] dispatches to people who are not grateful to Him, nor supplicate to Him.’ Then he said: ‘Do you know what is above you?’ They said: ‘Allah and His Messenger know better.’ He said: ‘Indeed it is a preserved canopy of the firmament whose surge is restrained.’ Then he said: ‘Do you know how much is between you and between it?’ They said: ‘Allah and His Messenger know better.’ He said: ‘Between you and it [is the distance] of five-hundred year.’ Then he said: ‘Do you know what is above that.’ They said: ‘Allah and His Messenger know better.’ He said: ‘Verily, above that are two Heavens, between the two of them there is a distance of five-hundred years’ – until he enumerated seven Heavens – ‘What is between each of the two Heavens is what is between the heavens and the earth.’ Then he said: ‘Do you know what is above that?’ They said: ‘Allah and His Messenger know better.’ He said: ‘Verily, above that is the Throne between it and the heavens is a distance [like] what is between two of the heavens.’ Then he said: ‘Do you know what is under you?’ They said: ‘Allah and His Messenger know better.’ He said: ‘Indeed it is the earth.’ Then he said: ‘Do you know what is under that?’ They said: ‘Allah and His Messenger know better.’ He said: ‘Verily, below it is another earth, between the two of which is a distance of five-hundred years.’ Until he enumerated seven earths: ‘Between every two earths is a distance of five-hundred years.’ Then he said: ‘By the One in Whose Hand is the soul of Muhammad! If you were to send [a man] down with a rope to the lowest earth, then he would descend upon Allah.’ Then he recited: He is Al-Awwal, Al-Akhir, Az-Zahir Al-Batin, and He has knowledge over all things.”
