الَّذِي جَعَلَ لَكُمُ الْأَرْضَ فِرَاشًا وَالسَّمَاءَ بِنَاءً وَأَنزَلَ مِنَ السَّمَاءِ مَاءً فَأَخْرَجَ بِهِ مِنَ الثَّمَرَاتِ رِزْقًا لَّكُمْ ۖ فَلَا تَجْعَلُوا لِلَّهِ أَندَادًا وَأَنتُمْ تَعْلَمُونَ ﴿٢٢ البقرة﴾

إِنَّا زَيَّنَّا ٱلسَّمَآءَ ٱلدُّنۡيَا بِزِينَةٍ ٱلۡكَوَاكِبِ (6) وَحِفۡظٗا مِّن كُلِّ شَيۡطَٰنٖ مَّارِدٖ (7) لَّا يَسَّمَّعُونَ إِلَى ٱلۡمَلَإِ ٱلۡأَعۡلَىٰ وَيُقۡذَفُونَ مِن كُلِّ جَانِبٖ (8)
