Way of Quran descending

All of the verses of Quran have descended from a source and invite persons to a right path.
In the doomsday, all of heavens will be doors of mercy;
وَفُتِحَتِ السَّمَاءُ فَكَانَتْ أَبْوَابًا
And the heavens shall be opened as if there were doors.

Quran states about divine messages and Quran descending
إِنَّا أَنزَلْنَاهُ فِی لَیْلَةٍ مُّبَارَكَةٍ ۚ إِنَّا كُنَّا مُنذِرِینَ
We sent it down during a Blessed Night: for We (ever) wish to warn (against Evil).
قُلْ إِنِّی عَلَىٰ بَیِّنَةٍ مِّن رَّبِّی وَكَذَّبْتُم بِهِ ۚ مَا عِندِی مَا تَسْتَعْجِلُونَ بِهِ ۚ إِنِ الْحُكْمُ إِلَّا لِلَّهِ ۖ یَقُصُّ الْحَقَّ ۖ وَهُوَ خَیْرُ الْفَاصِلِینَ
Say: "For me, I (work) on a clear sign from my Lord, but ye reject Him. What ye would see hastened, is not in my power. The command rests with none but Allah: He declares the truth, and He is the best of judges''.
Quran expresses all of trains and guides human. Quran expresses three principles, monotheism, prophesy and resurrection. Quran states
إِنْ أَنتَ إِلَّا نَذِیرٌ
Thou art no other than a warner.
قُل لَّا أَمْلِكُ لِنَفْسِی نَفْعًا وَلَا ضَرًّا إِلَّا مَا شَاءَ اللَّهُ ۚ وَلَوْ كُنتُ أَعْلَمُ الْغَیْبَ لَاسْتَكْثَرْتُ مِنَ الْخَیْرِ وَمَا مَسَّنِیَ السُّوءُ ۚ إِنْ أَنَا إِلَّا نَذِیرٌ وَبَشِیرٌ لِّقَوْمٍ یُؤْمِنُونَ
Say: "I have no power over any good or harm to myself except as Allah willeth. If I had knowledge of the unseen, I should have multiplied all good, and no evil should have touched me: I am but a warner, and a bringer of glad tidings to those who have faith.

إِنَّا جَعَلْنَاهُ قُرْآنًا عَرَبِیًّا لَّعَلَّكُمْ تَعْقِلُونَ
We have made it a Qur´an in Arabic, that ye may be able to understand (and learn wisdom). )
وَإِنَّهُ فِی أُمِّ الْكِتَابِ لَدَیْنَا لَعَلِیٌّ حَكِیمٌ
And verily, it is in the Mother of the Book, in Our Presence, high (in dignity), full of wisdom.
زَلَ بِهِ الرُّوحُ الْأَمِینُ
With it came down the spirit of Faith and Truth.
عَلَىٰ قَلْبِكَ لِتَكُونَ مِنَ الْمُنذِرِینَ
.To thy heart and mind, that thou mayest admonish
Quran descended from source of divine messages and promoted from the world of human.
God states that we descended Quran that expresses trains overnight. In other cases, God states we descended gradually;
بِالْبَیِّنَاتِ وَالزُّبُرِ ۗ وَأَنزَلْنَا إِلَیْكَ الذِّكْرَ لِتُبَیِّنَ لِلنَّاسِ مَا نُزِّلَ إِلَیْهِمْ وَلَعَلَّهُمْ یَتَفَكَّرُونَ
We sent them) with Clear Signs and Books of dark prophecies; and We have sent down unto thee (also) the Message; that thou mayest explain clearly to men what is sent for them, and that they may give thought.
وَقُرْآنًا فَرَقْنَاهُ لِتَقْرَأَهُ عَلَى النَّاسِ عَلَىٰ مُكْثٍ وَنَزَّلْنَاهُ تَنزِیلًا
It is) a Qur´an which We have divided (into parts from time to time), in order that thou mightest recite it to men at intervals: We have revealed it by stages.
وَقَالَ الَّذِینَ كَفَرُوا لَوْلَا نُزِّلَ عَلَیْهِ الْقُرْآنُ جُمْلَةً وَاحِدَةً ۚ كَذَٰلِكَ لِنُثَبِّتَ بِهِ فُؤَادَكَ ۖ وَرَتَّلْنَاهُ تَرْتِیلًا
Those who reject Faith say: "Why is not the Qur´an revealed to him all at once? Thus (is it revealed), that We may strengthen thy heart thereby, and We have rehearsed it to thee in slow, well-arranged stages, gradually.
Quran states
إِنَّا أَنزَلْنَاهُ فِی لَیْلَةِ الْقَدْرِ
We have indeed revealed this (Message) in the Night of Power.
شَهْرُ رَمَضَانَ الَّذِی أُنزِلَ فِیهِ الْقُرْآنُ هُدًى لِّلنَّاسِ وَبَیِّنَاتٍ مِّنَ الْهُدَىٰ وَالْفُرْقَانِ ۚ فَمَن شَهِدَ مِنكُمُ الشَّهْرَ فَلْیَصُمْهُ ۖ وَمَن كَانَ مَرِیضًا أَوْ عَلَىٰ سَفَرٍ فَعِدَّةٌ مِّنْ أَیَّامٍ أُخَرَ ۗ یُرِیدُ اللَّهُ بِكُمُ الْیُسْرَ وَلَا یُرِیدُ بِكُمُ الْعُسْرَ وَلِتُكْمِلُوا الْعِدَّةَ وَلِتُكَبِّرُوا اللَّهَ عَلَىٰ مَا هَدَاكُمْ وَلَعَلَّكُمْ تَشْكُرُونَ
Ramadhan is the (month) in which was sent down the Qur´an, as a guide to mankind, also clear (Signs) for guidance and judgment (Between right and wrong). So every one of you who is present (at his home) during that month should spend it in fasting, but if any one is ill, or on a journey, the prescribed period (Should be made up) by days later. Allah intends every facility for you; He does not want to put to difficulties. (He wants you) to complete the prescribed period, and to glorify Him in that He has guided you; and perchance ye shall be grateful.

All of the verses of Quran are coherent and there is no difference among verses of Quran;
أَفَلَا یَتَدَبَّرُونَ الْقُرْآنَ ۚ وَلَوْ كَانَ مِنْ عِندِ غَیْرِ اللَّهِ لَوَجَدُوا فِیهِ اخْتِلَافًا كَثِیرًا
Do they not consider the Qur´an (with care)? Had it been from other Than Allah, they would surely have found therein Much discrepancy.
Quran states
اللَّهُ نَزَّلَ أَحْسَنَ الْحَدِیثِ كِتَابًا مُّتَشَابِهًا مَّثَانِیَ تَقْشَعِرُّ مِنْهُ جُلُودُ الَّذِینَ یَخْشَوْنَ رَبَّهُمْ ثُمَّ تَلِینُ جُلُودُهُمْ وَقُلُوبُهُمْ إِلَىٰ ذِكْرِ اللَّهِ ۚ ذَٰلِكَ هُدَى اللَّهِ یَهْدِی بِهِ مَن یَشَاءُ ۚ وَمَن یُضْلِلِ اللَّهُ فَمَا لَهُ مِنْ هَادٍ
Allah has revealed (from time to time) the most beautiful Message in the form of a Book, consistent with itself, (yet) repeating (its teaching in various aspects): the skins of those who fear their Lord tremble thereat; then their skins and their hearts do soften to the celebration of Allah´s praises. Such is the guidance of Allah: He guides therewith whom He pleases, but such as Allah leaves to stray, can have none to guide.
Quran reminds events of human societies such as war and peace, economic issues and explains rules related to them. Therefore, it is impossible that Quran descended at once;
قَدْ سَمِعَ اللَّهُ قَوْلَ الَّتِی تُجَادِلُكَ فِی زَوْجِهَا وَتَشْتَكِی إِلَى اللَّهِ وَاللَّهُ یَسْمَعُ تَحَاوُرَكُمَا ۚ إِنَّ اللَّهَ سَمِیعٌ بَصِیرٌ
Allah has indeed heard (and accepted) the statement of the woman who pleads with thee concerning her husband and carries her complaint (in prayer) to Allah: and Allah (always) hears the arguments between both sides among you: for Allah hears and sees (all things).
Quran states
فِیهَا یُفْرَقُ كُلُّ أَمْرٍ حَكِیمٍ
In the (Night) is made distinct every affair of wisdom.
أَمْرًا مِّنْ عِندِنَا ۚ إِنَّا كُنَّا مُرْسِلِینَ
By command, from Our Presence. For We (ever) send (revelations).
رَحْمَةً مِّن رَّبِّكَ ۚ إِنَّهُ هُوَ السَّمِیعُ الْعَلِیمُ
.( As Mercy from thy Lord: for He hears and knows (all things
وَإِن مِّن شَیْءٍ إِلَّا عِندَنَا خَزَائِنُهُ وَمَا نُنَزِّلُهُ إِلَّا بِقَدَرٍ مَّعْلُومٍ
And there is not a thing but its (sources and) treasures (inexhaustible) are with Us; but We only send down thereof in due and ascertainable measures.
لَقَدْ مَنَّ اللَّهُ عَلَى الْمُؤْمِنِینَ إِذْ بَعَثَ فِیهِمْ رَسُولًا مِّنْ أَنفُسِهِمْ یَتْلُو عَلَیْهِمْ آیَاتِهِ وَیُزَكِّیهِمْ وَیُعَلِّمُهُمُ الْكِتَابَ وَالْحِكْمَةَ وَإِن كَانُوا مِن قَبْلُ لَفِی ضَلَالٍ مُّبِینٍ
Allah did confer a great favour on the believers when He sent among them a messenger from among themselves, rehearsing unto them the Signs of Allah, sanctifying them, and instructing them in Scripture and Wisdom, while, before that, they had been in manifest error.
وَلَا تُؤْمِنُوا إِلَّا لِمَن تَبِعَ دِینَكُمْ قُلْ إِنَّ الْهُدَىٰ هُدَى اللَّهِ أَن یُؤْتَىٰ أَحَدٌ مِّثْلَ مَا أُوتِیتُمْ أَوْ یُحَاجُّوكُمْ عِندَ رَبِّكُمْ ۗ قُلْ إِنَّ الْفَضْلَ بِیَدِ اللَّهِ یُؤْتِیهِ مَن یَشَاءُ ۗ وَاللَّهُ وَاسِعٌ عَلِیمٌ
And believe no one unless he follows your religion." Say: "True guidance is the Guidance of Allah: (Fear ye) Lest a revelation be sent to someone (else) Like unto that which was sent unto you? or that those (Receiving such revelation) should engage you in argument before your Lord?" Say: "All bounties are in the hand of Allah: He granteth them to whom He pleaseth: And Allah careth for all, and He knoweth all things.
وَاعْتَصِمُوا بِحَبْلِ اللَّهِ جَمِیعًا وَلَا تَفَرَّقُوا ۚ وَاذْكُرُوا نِعْمَتَ اللَّهِ عَلَیْكُمْ إِذْ كُنتُمْ أَعْدَاءً فَأَلَّفَ بَیْنَ قُلُوبِكُمْ فَأَصْبَحْتُم بِنِعْمَتِهِ إِخْوَانًا وَكُنتُمْ عَلَىٰ شَفَا حُفْرَةٍ مِّنَ النَّارِ فَأَنقَذَكُم مِّنْهَا ۗ كَذَٰلِكَ یُبَیِّنُ اللَّهُ لَكُمْ آیَاتِهِ لَعَلَّكُمْ تَهْتَدُونَ
And hold fast, all together, by the rope which Allah (stretches out for you), and be not divided among yourselves; and remember with gratitude Allah´s favour on you; for ye were enemies and He joined your hearts in love, so that by His Grace, ye became brethren; and ye were on the brink of the pit of Fire, and He saved you from it. Thus doth Allah make His Signs clear to you: That ye may be guided.
یَا أَیُّهَا الَّذِینَ آمَنُوا لَا تَكُونُوا كَالَّذِینَ كَفَرُوا وَقَالُوا لِإِخْوَانِهِمْ إِذَا ضَرَبُوا فِی الْأَرْضِ أَوْ كَانُوا غُزًّى لَّوْ كَانُوا عِندَنَا مَا مَاتُوا وَمَا قُتِلُوا لِیَجْعَلَ اللَّهُ ذَٰلِكَ حَسْرَةً فِی قُلُوبِهِمْ ۗ وَاللَّهُ یُحْیِی وَیُمِیتُ ۗ وَاللَّهُ بِمَا تَعْمَلُونَ بَصِیرٌ
O ye who believe! Be not like the Unbelievers, who say of their brethren, when they are travelling through the Earth or engaged in fighting: "If they had stayed with us, they would not have died, or been slain." This that Allah may make it a cause of sighs and regrets in their hearts. It is Allah that gives Life and Death, and Allah sees well all that ye do.
فَبِمَا رَحْمَةٍ مِّنَ اللَّهِ لِنتَ لَهُمْ ۖ وَلَوْ كُنتَ فَظًّا غَلِیظَ الْقَلْبِ لَانفَضُّوا مِنْ حَوْلِكَ ۖ فَاعْفُ عَنْهُمْ وَاسْتَغْفِرْ لَهُمْ وَشَاوِرْهُمْ فِی الْأَمْرِ ۖ فَإِذَا عَزَمْتَ فَتَوَكَّلْ عَلَى اللَّهِ ۚ إِنَّ اللَّهَ یُحِبُّ الْمُتَوَكِّلِینَ
It is part of the Mercy of Allah that thou dost deal gently with them Wert thou severe or harsh-hearted, they would have broken away from about thee: so pass over (Their faults), and ask for (Allah´s) forgiveness for them; and consult them in affairs (of moment). Then, when thou hast Taken a decision put thy trust in Allah. For Allah loves those who put their trust (in Him).
وَلِیَعْلَمَ الَّذِینَ نَافَقُوا ۚ وَقِیلَ لَهُمْ تَعَالَوْا قَاتِلُوا فِی سَبِیلِ اللَّهِ أَوِ ادْفَعُوا ۖ قَالُوا لَوْ نَعْلَمُ قِتَالًا لَّاتَّبَعْنَاكُمْ ۗ هُمْ لِلْكُفْرِ یَوْمَئِذٍ أَقْرَبُ مِنْهُمْ لِلْإِیمَانِ ۚ یَقُولُونَ بِأَفْوَاهِهِم مَّا لَیْسَ فِی قُلُوبِهِمْ ۗ وَاللَّهُ أَعْلَمُ بِمَا یَكْتُمُونَ
And the Hypocrites also. These were told: "Come, fight in the way of Allah, or (at least) drive (The foe from your city)." They said: "Had we known how to fight, we should certainly have followed you." They were that day nearer to Unbelief than to Faith, saying with their lips what was not in their hearts but Allah hath full knowledge of all they conceal.
مَّا كَانَ اللَّهُ لِیَذَرَ الْمُؤْمِنِینَ عَلَىٰ مَا أَنتُمْ عَلَیْهِ حَتَّىٰ یَمِیزَ الْخَبِیثَ مِنَ الطَّیِّبِ ۗ وَمَا كَانَ اللَّهُ لِیُطْلِعَكُمْ عَلَى الْغَیْبِ وَلَٰكِنَّ اللَّهَ یَجْتَبِی مِن رُّسُلِهِ مَن یَشَاءُ ۖ فَآمِنُوا بِاللَّهِ وَرُسُلِهِ ۚ وَإِن تُؤْمِنُوا وَتَتَّقُوا فَلَكُمْ أَجْرٌ عَظِیمٌ
Allah will not leave the believers in the state in which ye are now, until He separates what is evil from what is good nor will He disclose to you the secrets of the Unseen. But He chooses of His Messengers (For the purpose) whom He pleases. So believe in Allah. And His messengers: And if ye believe and do right, ye have a reward without measure.
وَلَا یَحْسَبَنَّ الَّذِینَ یَبْخَلُونَ بِمَا آتَاهُمُ اللَّهُ مِن فَضْلِهِ هُوَ خَیْرًا لَّهُم ۖ بَلْ هُوَ شَرٌّ لَّهُمْ ۖ سَیُطَوَّقُونَ مَا بَخِلُوا بِهِ یَوْمَ الْقِیَامَةِ ۗ وَلِلَّهِ مِیرَاثُ السَّمَاوَاتِ وَالْأَرْضِ ۗ وَاللَّهُ بِمَا تَعْمَلُونَ خَبِیرٌ
And let not those who covetously withhold of the gifts which Allah Hath given them of His Grace, think that it is good for them: Nay, it will be the worse for them: soon shall the things which they covetously withheld be tied to their necks Like a twisted collar, on the Day of Judgment. To Allah belongs the heritage of the heavens and the earth; and Allah is well-acquainted with all that ye do.
لَّقَدْ سَمِعَ اللَّهُ قَوْلَ الَّذِینَ قَالُوا إِنَّ اللَّهَ فَقِیرٌ وَنَحْنُ أَغْنِیَاءُ ۘ سَنَكْتُبُ مَا قَالُوا وَقَتْلَهُمُ الْأَنبِیَاءَ بِغَیْرِ حَقٍّ وَنَقُولُ ذُوقُوا عَذَابَ الْحَرِیقِ
Allah hath heard the taunt of those who say: "Truly, Allah is indigent and we are rich!"- We shall certainly record their word and (their act) of slaying the prophets in defiance of right, and We shall say: "Taste ye the penalty of the Scorching Fire''.
