Creation as reason of God monotheism in Quran

Reasons of creation have been expressed in different ways in order to represent unity of immaculate God in different ways and has explained different ways of creation such as persons and plants.
Quran expresses issue of creation generally apart from mind of persons. Quran states
قُلْ مَن رَّبُّ السَّمَاوَاتِ وَالْأَرْضِ قُلِ اللَّهُ ۚ قُلْ أَفَاتَّخَذْتُم مِّن دُونِهِ أَوْلِيَاءَ لَا يَمْلِكُونَ لِأَنفُسِهِمْ نَفْعًا وَلَا ضَرًّا ۚ قُلْ هَلْ يَسْتَوِي الْأَعْمَىٰ وَالْبَصِيرُ أَمْ هَلْ تَسْتَوِي الظُّلُمَاتُ وَالنُّورُ ۗ أَمْ جَعَلُوا لِلَّهِ شُرَكَاءَ خَلَقُوا كَخَلْقِهِ فَتَشَابَهَ الْخَلْقُ عَلَيْهِمْ ۚ قُلِ اللَّهُ خَالِقُ كُلِّ شَيْءٍ وَهُوَ الْوَاحِدُ الْقَهَّارُ
Say: "Who is the Lord and Sustainer of the heavens and the earth?" Say: "(It is) Allah." Say: "Do ye then take (for worship) protectors other than Him, such as have no power either for good or for harm to themselves?" Say: "Are the blind equal with those who see? Or the depths of darkness equal with light?" Or do they assign to Allah partners who have created (anything) as He has created, so that the creation seemed to them similar? Say: "Allah is the Creator of all things: He is the One, the Supreme and Irresistible''.
الَّذِي لَهُ مُلْكُ السَّمَاوَاتِ وَالْأَرْضِ وَلَمْ يَتَّخِذْ وَلَدًا وَلَمْ يَكُن لَّهُ شَرِيكٌ فِي الْمُلْكِ وَخَلَقَ كُلَّ شَيْءٍ فَقَدَّرَهُ تَقْدِيرًا
He to whom belongs the dominion of the heavens and the earth: no son has He begotten, nor has He a partner in His dominion: it is He who created all things, and ordered them in due proportions.
إِنَّا كُلَّ شَيْءٍ خَلَقْنَاهُ بِقَدَرٍ
Verily, all things have We created in proportion and measure.
وَمَا أَمْرُنَا إِلَّا وَاحِدَةٌ كَلَمْحٍ بِالْبَصَرِ
.And Our Command is but a single (Act),- like the twinkling of an eye
According to the above verses, creation is without purpose and futilely, but creation is based on features that immaculate God has determined so that God fulfills his certain role and duty among creatures.
There are verses about creation in different ways;
خَلَقَ السَّمَاوَاتِ بِغَيْرِ عَمَدٍ تَرَوْنَهَا ۖ وَأَلْقَىٰ فِي الْأَرْضِ رَوَاسِيَ أَن تَمِيدَ بِكُمْ وَبَثَّ فِيهَا مِن كُلِّ دَابَّةٍ ۚ وَأَنزَلْنَا مِنَ السَّمَاءِ مَاءً فَأَنبَتْنَا فِيهَا مِن كُلِّ زَوْجٍ كَرِيمٍ
He created the heavens without any pillars that ye can see; He set on the earth mountains standing firm, lest it should shake with you; and He scattered through it beasts of all kinds. We send down rain from the sky, and produce on the earth every kind of noble creature, in pairs.
هَٰذَا خَلْقُ اللَّهِ فَأَرُونِي مَاذَا خَلَقَ الَّذِينَ مِن دُونِهِ ۚ بَلِ الظَّالِمُونَ فِي ضَلَالٍ مُّبِينٍ
Such is the Creation of Allah: now show Me what is there that others besides Him have created: nay, but the Transgressors are in manifest error.
أَلَمْ تَرَ أَنَّ اللَّهَ أَنزَلَ مِنَ السَّمَاءِ مَاءً فَأَخْرَجْنَا بِهِ ثَمَرَاتٍ مُّخْتَلِفًا أَلْوَانُهَا ۚ وَمِنَ الْجِبَالِ جُدَدٌ بِيضٌ وَحُمْرٌ مُّخْتَلِفٌ أَلْوَانُهَا وَغَرَابِيبُ سُودٌ
Seest thou not that Allah sends down rain from the sky? With it We then bring out produce of various colours. And in the mountains are tracts white and red, of various shades of colour, and black intense in hue.
وَمِنَ النَّاسِ وَالدَّوَابِّ وَالْأَنْعَامِ مُخْتَلِفٌ أَلْوَانُهُ كَذَٰلِكَ ۗ إِنَّمَا يَخْشَى اللَّهَ مِنْ عِبَادِهِ الْعُلَمَاءُ ۗ إِنَّ اللَّهَ عَزِيزٌ غَفُورٌ
And so amongst men and crawling creatures and cattle, are they of various colours. Those truly fear Allah, among His Servants, who have knowledge: for Allah is Exalted in Might, Oft-Forgiving.
There are a lot of differences and varieties among animals and there are such differences among people in height, appearance, race and so forth as Quran states
وَمِنْ آيَاتِهِ خَلْقُ السَّمَاوَاتِ وَالْأَرْضِ وَاخْتِلَافُ أَلْسِنَتِكُمْ وَأَلْوَانِكُمْ ۚ إِنَّ فِي ذَٰلِكَ لَآيَاتٍ لِّلْعَالِمِينَ
And among His Signs is the creation of the heavens and the earth, and the variations in your languages and your colours: verily in that are Signs for those who know.
God states about existence
وَمَن يَقُلْ مِنْهُمْ إِنِّي إِلَٰهٌ مِّن دُونِهِ فَذَٰلِكَ نَجْزِيهِ جَهَنَّمَ ۚ كَذَٰلِكَ نَجْزِي الظَّالِمِينَ
If any of them should say, "I am a god besides Him", such a one We should reward with Hell: thus do We reward those who do wrong.
أَوَلَمْ يَرَ الَّذِينَ كَفَرُوا أَنَّ السَّمَاوَاتِ وَالْأَرْضَ كَانَتَا رَتْقًا فَفَتَقْنَاهُمَا ۖ وَجَعَلْنَا مِنَ الْمَاءِ كُلَّ شَيْءٍ حَيٍّ ۖ أَفَلَا يُؤْمِنُونَ
Do not the Unbelievers see that the heavens and the earth were joined together (as one unit of creation), before we clove them asunder? We made from water every living thing. Will they not then believe?
وَجَعَلْنَا فِي الْأَرْضِ رَوَاسِيَ أَن تَمِيدَ بِهِمْ وَجَعَلْنَا فِيهَا فِجَاجًا سُبُلًا لَّعَلَّهُمْ يَهْتَدُونَ
And We have set on the earth mountains standing firm, lest it should shake with them, and We have made therein broad highways (between mountains) for them to pass through: that they may receive Guidance.
وَجَعَلْنَا السَّمَاءَ سَقْفًا مَّحْفُوظًا ۖ وَهُمْ عَنْ آيَاتِهَا مُعْرِضُونَ
And We have made the heavens as a canopy well guarded: yet do they turn away from the Signs which these things (point to).
وَهُوَ الَّذِي خَلَقَ اللَّيْلَ وَالنَّهَارَ وَالشَّمْسَ وَالْقَمَرَ ۖ كُلٌّ فِي فَلَكٍ يَسْبَحُونَ
It is He Who created the Night and the Day, and the sun and the moon: all (the celestial bodies) swim along, each in its rounded course.
Quran states about realities related to exalted God
قُلْ أَئِنَّكُمْ لَتَكْفُرُونَ بِالَّذِي خَلَقَ الْأَرْضَ فِي يَوْمَيْنِ وَتَجْعَلُونَ لَهُ أَندَادًا ۚ ذَٰلِكَ رَبُّ الْعَالَمِينَ
Say: Is it that ye deny Him Who created the earth in two Days? And do ye join equals with Him? He is the Lord of (all) the Worlds.
وَجَعَلَ فِيهَا رَوَاسِيَ مِن فَوْقِهَا وَبَارَكَ فِيهَا وَقَدَّرَ فِيهَا أَقْوَاتَهَا فِي أَرْبَعَةِ أَيَّامٍ سَوَاءً لِّلسَّائِلِينَ
He set on the (earth), mountains standing firm, high above it, and bestowed blessings on the earth, and measure therein all things to give them nourishment in due proportion, in four Days, in accordance with (the needs of) those who seek (Sustenance).
ثُمَّ اسْتَوَىٰ إِلَى السَّمَاءِ وَهِيَ دُخَانٌ فَقَالَ لَهَا وَلِلْأَرْضِ ائْتِيَا طَوْعًا أَوْ كَرْهًا قَالَتَا أَتَيْنَا طَائِعِينَ
Moreover He comprehended in His design the sky, and it had been (as) smoke: He said to it and to the earth: "Come ye together, willingly or unwillingly." They said: "We do come (together), in willing obedience''.
فَقَضَاهُنَّ سَبْعَ سَمَاوَاتٍ فِي يَوْمَيْنِ وَأَوْحَىٰ فِي كُلِّ سَمَاءٍ أَمْرَهَا ۚ وَزَيَّنَّا السَّمَاءَ الدُّنْيَا بِمَصَابِيحَ وَحِفْظًا ۚ ذَٰلِكَ تَقْدِيرُ الْعَزِيزِ الْعَلِيمِ
So He completed them as seven firmaments in two Days, and He assigned to each heaven its duty and command. And We adorned the lower heaven with lights, and (provided it) with guard. Such is the Decree of (Him) the Exalted in Might, Full of Knowledge.
There are general verses that refer to creation of human and unity of immaculate God in creation;
خَلَقَ الْإِنسَانَ مِن صَلْصَالٍ كَالْفَخَّارِ
. He created man from sounding clay like unto pottery
In the following verses, God has referred to another stage of human creation;
هَلْ أَتَىٰ عَلَى الْإِنسَانِ حِينٌ مِّنَ الدَّهْرِ لَمْ يَكُن شَيْئًا مَّذْكُورًا
Has there not been over Man a long period of Time, when he was nothing - (not even) mentioned?
إِنَّا خَلَقْنَا الْإِنسَانَ مِن نُّطْفَةٍ أَمْشَاجٍ نَّبْتَلِيهِ فَجَعَلْنَاهُ سَمِيعًا بَصِيرًا
Verily We created Man from a drop of mingled sperm, in order to try him: So We gave him (the gifts), of Hearing and Sight.
فَلْيَنظُرِ الْإِنسَانُ مِمَّ خُلِقَ
Now let man but think from what he is created.
خُلِقَ مِن مَّاءٍ دَافِقٍ
He is created from a drop emitted.
يَخْرُجُ مِن بَيْنِ الصُّلْبِ وَالتَّرَائِبِ
Proceeding from between the backbone and the ribs.
نَحْنُ خَلَقْنَاكُمْ فَلَوْلَا تُصَدِّقُونَ
It is We Who have created you: why will ye not witness the Truth?
أَفَرَأَيْتُم مَّا تُمْنُونَ
. Do ye then see?- The (human Seed) that ye throw out
أَأَنتُمْ تَخْلُقُونَهُ أَمْ نَحْنُ الْخَالِقُونَ
.Is it ye who create it, or are We the Creators
أَوَلَمْ يَرَ الْإِنسَانُ أَنَّا خَلَقْنَاهُ مِن نُّطْفَةٍ فَإِذَا هُوَ خَصِيمٌ مُّبِينٌ
Doth not man see that it is We Who created him from sperm? yet behold! he (stands forth) as an open adversary.
اقْرَأْ بِاسْمِ رَبِّكَ الَّذِي خَلَقَ
Proclaim! (or read!) in the name of thy Lord and Cherisher, Who created.
خَلَقَ الْإِنسَانَ مِنْ عَلَقٍ
.Created man, out of a (mere) clot of congealed blood
There are verses of Quran that explain about creation of human in detail;
وَلَقَدْ خَلَقْنَا الْإِنسَانَ مِن صَلْصَالٍ مِّنْ حَمَإٍ مَّسْنُونٍ
.We created man from sounding clay, from mud moulded into shape
وَالْجَانَّ خَلَقْنَاهُ مِن قَبْلُ مِن نَّارِ السَّمُومِ
And the Jinn race, We had created before, from the fire of a scorching wind.
وَإِذْ قَالَ رَبُّكَ لِلْمَلَائِكَةِ إِنِّي خَالِقٌ بَشَرًا مِّن صَلْصَالٍ مِّنْ حَمَإٍ مَّسْنُونٍ
Behold! thy Lord said to the angels: "I am about to create man, from sounding clay from mud moulded into shape''.
فَإِذَا سَوَّيْتُهُ وَنَفَخْتُ فِيهِ مِن رُّوحِي فَقَعُوا لَهُ سَاجِدِينَ
When I have fashioned him (in due proportion) and breathed into him of My spirit, fall ye down in obeisance unto him.
الَّذِي أَحْسَنَ كُلَّ شَيْءٍ خَلَقَهُ ۖ وَبَدَأَ خَلْقَ الْإِنسَانِ مِن طِينٍ
He Who has made everything which He has created most good: He began the creation of man with (nothing more than) clay.
ثُمَّ جَعَلَ نَسْلَهُ مِن سُلَالَةٍ مِّن مَّاءٍ مَّهِينٍ
And made his progeny from a quintessence of the nature of a fluid despised.
ثُمَّ سَوَّاهُ وَنَفَخَ فِيهِ مِن رُّوحِهِ ۖ وَجَعَلَ لَكُمُ السَّمْعَ وَالْأَبْصَارَ وَالْأَفْئِدَةَ ۚ قَلِيلًا مَّا تَشْكُرُونَ
But He fashioned him in due proportion, and breathed into him something of His spirit. And He gave you (the faculties of) hearing and sight and feeling (and understanding): little thanks do ye give.
All of the above verses refer to a stage or stages of human creation. In some verses, there is relationship between stages and resurrection after death.
Quran states
مَّا أَشْهَدتُّهُمْ خَلْقَ السَّمَاوَاتِ وَالْأَرْضِ وَلَا خَلْقَ أَنفُسِهِمْ وَمَا كُنتُ مُتَّخِذَ الْمُضِلِّينَ عَضُدًا
I called them not to witness the creation of the heavens and the earth, nor (even) their own creation: nor is it for helpers such as Me to take as lead (men) astray.
وَوُضِعَ الْكِتَابُ فَتَرَى الْمُجْرِمِينَ مُشْفِقِينَ مِمَّا فِيهِ وَيَقُولُونَ يَا وَيْلَتَنَا مَالِ هَٰذَا الْكِتَابِ لَا يُغَادِرُ صَغِيرَةً وَلَا كَبِيرَةً إِلَّا أَحْصَاهَا ۚ وَوَجَدُوا مَا عَمِلُوا حَاضِرًا ۗ وَلَا يَظْلِمُ رَبُّكَ أَحَدًا
And the Book (of Deeds) will be placed (before you); and thou wilt see the sinful in great terror because of what is (recorded) therein; they will say, "Ah! woe to us! what a Book is this! It leaves out nothing small or great, but takes account thereof!" They will find all that they did, placed before them: And not one will thy Lord treat with injustice.
وَإِذْ قُلْنَا لِلْمَلَائِكَةِ اسْجُدُوا لِآدَمَ فَسَجَدُوا إِلَّا إِبْلِيسَ كَانَ مِنَ الْجِنِّ فَفَسَقَ عَنْ أَمْرِ رَبِّهِ ۗ أَفَتَتَّخِذُونَهُ وَذُرِّيَّتَهُ أَوْلِيَاءَ مِن دُونِي وَهُمْ لَكُمْ عَدُوٌّ ۚ بِئْسَ لِلظَّالِمِينَ بَدَلًا
Behold! We said to the angels, "Bow down to Adam": They bowed down except Iblis. He was one of the Jinns, and he broke the Command of his Lord. Will ye then take him and his progeny as protectors rather than Me? And they are enemies to you! Evil would be the exchange for the wrong-doers.
وَكَذَٰلِكَ بَعَثْنَاهُمْ لِيَتَسَاءَلُوا بَيْنَهُمْ ۚ قَالَ قَائِلٌ مِّنْهُمْ كَمْ لَبِثْتُمْ ۖ قَالُوا لَبِثْنَا يَوْمًا أَوْ بَعْضَ يَوْمٍ ۚ قَالُوا رَبُّكُمْ أَعْلَمُ بِمَا لَبِثْتُمْ فَابْعَثُوا أَحَدَكُم بِوَرِقِكُمْ هَٰذِهِ إِلَى الْمَدِينَةِ فَلْيَنظُرْ أَيُّهَا أَزْكَىٰ طَعَامًا فَلْيَأْتِكُم بِرِزْقٍ مِّنْهُ وَلْيَتَلَطَّفْ وَلَا يُشْعِرَنَّ بِكُمْ أَحَدًا
Such (being their state), we raised them up (from sleep), that they might question each other. Said one of them, "How long have ye stayed (here)?" They said, "We have stayed (perhaps) a day, or part of a day." (At length) they (all) said, "Allah (alone) knows best how long ye have stayed here.... Now send ye then one of you with this money of yours to the town: let him find out which is the best food (to be had) and bring some to you, that (ye may) satisfy your hunger therewith: And let him behave with care and courtesy, and let him not inform any one about you.
