[A part of the same sermon, containing description of the sky] He has arranged the depressions and elevations of the openings of the sky. He has joined the breadths of its breaches, and has joined them with one another. He has made easy the approach to its heights for those (angels) who come down with His commands and those (angels) who go up with the deeds of the creatures. He called it when it was yet (in the form of) vapour. At once the links of its joints joined up. Then Allah opened up its closed door and put the sentinels of meteors at its holes, and held them with His hands (i.e. power) from falling into vastness of air.
