Musnad Ahmad

It is narrated from Hazrat Abu Hurairah (may Allah be pleased with him) that once we were sitting with the Noble Prophet (peace and blessings be upon him) when a cloud passed over from the sky. The Noble Prophet (peace and blessings be upon him) said, "Do you know what this is?" We said, "Allah and His Messenger know best." He said, "This is 'anan' which is driving the earth's moisture to those people who do not thank Allah and never call upon Him. Do you know what is above you?" We said, "Allah and His Messenger (peace and blessings be upon him) know best." He said, "Its name is 'Raqee‘', it is a folded wave and a protected roof. Do you know what the distance is between you and it?" We said, "Allah and His Messenger know best." He said, "The distance is five hundred years." Then he said, "Do you know what is above that?" We said, "Allah and His Messenger know best." He said, "The second sky." He said, "Do you know what the distance is between you and it?" We said, "Allah and His Messenger know best." He said, "The distance is five hundred years." In this way, after mentioning all seven skies, he said, "Do you know what is above that?" We said, "Allah and His Messenger know best." He said, "Above that is the Throne (Arsh). Do you know what the distance is between it and the seventh sky?" We said, "Allah and His Messenger (peace and blessings be upon him) know best." He said, "The distance is five hundred years." He said, "Do you know what is beneath you?" We said, "Allah and His Messenger (peace and blessings be upon him) know best." He said, "The earth." He said, "Do you know what is beneath that?" We said, "Allah and His Messenger (peace and blessings be upon him) know best." He said, "The second earth." He said, "Do you know what the distance is between the two?" We said, "Allah and His Messenger (peace and blessings be upon him) know best." He said, "The distance is seven hundred years." In this way, after mentioning all seven earths, he said, "By Allah, if any one of you were to hang down with a rope to the seventh earth, he would reach it." Then the Prophet (peace and blessings be upon him) recited this verse: "He is the First and the Last, the Manifest and the Hidden, and He is, of all things, Knowing."
