And We have indeed made the Qur'an easy to understand and remember, then is there any that will remember (or receive admonition)?

وَالَّذِينَ يَدْعُونَ مِنْ دُونِ اللَّهِ لاَ يَخْلُقُونَ شَيْئًا وَهُمْ يُخْلَقُونَ (النحل: 20).
أَمْوَاتٌ غَيْرُ أَحْيَاءٍ وَمَا يَشْعُرُونَ أَيَّانَ يُبْعَثُونَ (النحل: 21

20. Those whom they invoke besides Allah have not created anything, but are themselves created.

21. (They are) dead, lifeless, and they know not when they will be raised up.

يُولِجُ اللَّيْلَ فِي النَّهَارِ وَيُولِجُ النَّهَارَ فِي اللَّيْلِ وَسَخَّرَ الشَّمْسَ وَالْقَمَرَ كُلٌّ يَجْرِي ِلأَجَلٍ مُسَمًّى ذَلِكُمْ اللَّهُ رَبُّكُمْ لَهُ الْمُلْكُ وَالَّذِينَ تَدْعُونَ مِنْ دُونِهِ مَا يَمْلِكُونَ مِنْ قِطْمِيرٍ (فاطر: 13).
إِنْ تَدْعُوهُمْ لاَ يَسْمَعُوا دُعَاءَكُمْ وَلَوْ سَمِعُوا مَا اسْتَجَابُوا لَكُمْ وَيَوْمَ الْقِيَامَةِ يَكْفُرُونَ بِشِرْكِكُمْ وَلاَ يُنَبِّئُكَ مِثْلُ خَبِيرٍ (فاطر: 14

13. He merges the night into the day (i.e. the decrease in the hours of the night are added to the hours of the day), and He merges the day into the night (i.e. the decrease in the hours of the day are added to the hours of the night). And He has subjected the sun and the moon, each runs its course for a term appointed. Such is Allah your Lord; His is the kingdom. And those, whom you invoke or call upon instead of Him, own not even a Qitmir (the thin membrane over the date-stone).

14. If you invoke (or call upon) them, they hear not your call, and if (in case) they were to hear, they could not grant it (your request) to you. And on the Day of Resurrection, they will disown your worshipping them. And none can inform you (O Muhammad ) like Him Who is the All-Knower (of each and everything).
