The Adornment and Protection of the Heaven comes from Allah Allah says,إِنَّا زَيَّنَّا السَّمَاء الدُّنْيَا بِزِينَةٍ الْكَوَاكِبِVerily, We have adorned the near heaven with the stars.Allah tells us that He has adorned the lowest heaven with the heavenly bodies for those among the people of the earth who look at it. The stars and planets in the sky give light to the people of earth, as Allah says:وَلَقَدْ زَيَّنَّا السَّمَأءَ الدُّنْيَا بِمَصَـبِيحَ وَجَعَلْنَـهَا رُجُوماً لِّلشَّيَـطِينِ وَأَعْتَدْنَا لَهُمْ عَذَابَ السَّعِيرِAnd indeed We have adorned the nearest heaven with lamps, and We have made such lamps (as) missiles to drive away the Shayatin, and have prepared for them the torment of the blazing Fire. (67:5) وَلَقَدْ جَعَلْنَا فِى السَّمَاءِ بُرُوجًا وَزَيَّنَّـهَا لِلنَّـظِرِينَوَحَفِظْنَـهَا مِن كُلِّ شَيْطَـنٍ رَّجِيمٍإِلاَّ مَنِ اسْتَرَقَ السَّمْعَ فَأَتْبَعَهُ شِهَابٌ مُّبِينٌAnd indeed, We have put the big stars in the heaven and We beautified it for the beholders. And We have guarded it from every outcast Shaytan. Except him who steals the hearing then he is pursued by a clear flaming fire. (15:16-18)And Allah says here
