﴿ وَأَنَّا لَمَسْنَا ٱلسَّمَآءَ فَوَجَدْنَٰهَا مُلِئَتْ حَرَسًۭا شَدِيدًۭا وَشُهُبًۭا ﴾

“"'And [so it happened] that we reached out towards heaven: but we found it filled with mighty guards and flames,”

Allah then went back to the talk of the jinn, saying: (And (the jinn who had listened to the Qur'an said): We had sought the heaven) before we accepted faith (but had found it filled with strong warders) angels (and meteors) preventing them from listening.
