And whenever there comes down a surah (chapter from the Quran), they look at one another (saying): "Does any one see you?" Then they turn away. Allah has turned their hearts (from the light) because they are a people that understand not.

(This is) a surah (chapter of the Quran) which We have sent down and which We have enjoined, (ordained its legal laws) and in it We have revealed manifest Ayat (proofs, evidences, verses, lessons, signs, revelations lawful and unlawful things, and set boundries of Islamic Religion), that you may remember.

سورة الدخان
إِنَّآ أَنزَلۡنَٰهُ فِي لَيۡلَةٖ مُّبَٰرَكَةٍۚ إِنَّا كُنَّا مُنذِرِينَ
We sent it (this Quran) down on a blessed night [(i.e. night of Qadr, surah No: 97) in the month of Ramadan,, the 9th month of the Islamic calendar]. Verily, We are ever warning [mankind that Our Torment will reach those who disbelieve in Our Oneness of Lordship and in Our Oneness of worship].
Chapter 47, Verse 20, Muhammad
سورة محمد
وَيَقُولُ ٱلَّذِينَ ءَامَنُواْ لَوۡلَا نُزِّلَتۡ سُورَةٞۖ فَإِذَآ أُنزِلَتۡ سُورَةٞ مُّحۡكَمَةٞ وَذُكِرَ فِيهَا ٱلۡقِتَالُ رَأَيۡتَ ٱلَّذِينَ فِي قُلُوبِهِم مَّرَضٞ يَنظُرُونَ إِلَيۡكَ نَظَرَ ٱلۡمَغۡشِيِّ عَلَيۡهِ مِنَ ٱلۡمَوۡتِۖ فَأَوۡلَىٰ لَهُمۡ
Those who believe say: "Why is not a surah (chapter of the Quran) sent down (for us)? But when a decisive surah (explaining and ordering things) is sent down, and fighting (Jihad - holy fighting in Allah's Cause) is mentioned (i.e. ordained) therein, you will see those in whose hearts is a disease (of hypocrisy) looking at you with a look of one fainting to death. But it was better for them (hypocrites, to listen to Allah and to obey Him).
