The Holy Quran 41:12 — Surah Fussilat
Arabic text
فَقَضَىٰهُنَّ سَبْعَ سَمَـٰوَاتٍ فِى يَوْمَيْنِ وَأَوْحَىٰ فِى كُلِّ سَمَآءٍ أَمْرَهَا ۚ وَزَيَّنَّا ٱلسَّمَآءَ ٱلدُّنْيَا بِمَصَـٰبِيحَ وَحِفْظًا ۚ ذَٰلِكَ تَقْدِيرُ ٱلْعَزِيزِ ٱلْعَلِيمِ
Translation
Within two days, Allaah then made them (the skies) into seven skies, and issued a suitable command to (the angels occupying) each sky. Allaah decorated (adorned) the sky of the world with lanterns (stars) and made them a means of protection (to be used to pelt the Shayaateen who attempt to eavesdrop on the conversations of the angels). This is the decree of the Mighty, the Wise.
