Reasons of divine attention on monotheism of God in Quran

Reasons that Quran has expressed for unity of God are reasons that scientists consider as divine attention such as exact system over affairs of existence.
Attention of God includes existence and God organizes it as Quran states
اللَّهُ لَا إِلَٰهَ إِلَّا هُوَ الْحَيُّ الْقَيُّومُ ۚ لَا تَأْخُذُهُ سِنَةٌ وَلَا نَوْمٌ ۚ لَّهُ مَا فِي السَّمَاوَاتِ وَمَا فِي الْأَرْضِ ۗ مَن ذَا الَّذِي يَشْفَعُ عِندَهُ إِلَّا بِإِذْنِهِ ۚ يَعْلَمُ مَا بَيْنَ أَيْدِيهِمْ وَمَا خَلْفَهُمْ ۖ وَلَا يُحِيطُونَ بِشَيْءٍ مِّنْ عِلْمِهِ إِلَّا بِمَا شَاءَ ۚ وَسِعَ كُرْسِيُّهُ السَّمَاوَاتِ وَالْأَرْضَ ۖ وَلَا يَئُودُهُ حِفْظُهُمَا ۚ وَهُوَ الْعَلِيُّ الْعَظِيمُ
Allah! There is no god but He,-the Living, the Self-subsisting, Eternal. No slumber can seize Him nor sleep. His are all things in the heavens and on earth. Who is there can intercede in His presence except as He permitteth? He knoweth what (appeareth to His creatures as) before or after or behind them. Nor shall they compass aught of His knowledge except as He willeth. His Throne doth extend over the heavens and the earth, and He feeleth no fatigue in guarding and preserving them for He is the Most High, the Supreme (in glory).
Presentation of reasons of divine attention
Way of Quran in presentation of reasons of God attention is similar to its way in presentation of reasons of creation and in most cases, reasons of attention are in line with reasons of creation. Quran states
وَتَرَى الْجِبَالَ تَحْسَبُهَا جَامِدَةً وَهِيَ تَمُرُّ مَرَّ السَّحَابِ ۚ صُنْعَ اللَّهِ الَّذِي أَتْقَنَ كُلَّ شَيْءٍ ۚ إِنَّهُ خَبِيرٌ بِمَا تَفْعَلُونَ
Thou seest the mountains and thinkest them firmly fixed: but they shall pass away as the clouds pass away: (such is) the artistry of Allah, who disposes of all things in perfect order: for he is well acquainted with all that ye do.
A lot of verses have determined general grounds about existence, animals and plants as Quran states
اللَّهُ الَّذِي خَلَقَ السَّمَاوَاتِ وَالْأَرْضَ وَأَنزَلَ مِنَ السَّمَاءِ مَاءً فَأَخْرَجَ بِهِ مِنَ الثَّمَرَاتِ رِزْقًا لَّكُمْ ۖ وَسَخَّرَ لَكُمُ الْفُلْكَ لِتَجْرِيَ فِي الْبَحْرِ بِأَمْرِهِ ۖ وَسَخَّرَ لَكُمُ الْأَنْهَارَ
It is Allah Who hath created the heavens and the earth and sendeth down rain from the skies, and with it bringeth out fruits wherewith to feed you; it is He Who hath made the ships subject to you, that they may sail through the sea by His command; and the rivers (also) hath He made subject to you.
وَسَخَّرَ لَكُمُ الشَّمْسَ وَالْقَمَرَ دَائِبَيْنِ ۖ وَسَخَّرَ لَكُمُ اللَّيْلَ وَالنَّهَارَ
And He hath made subject to you the sun and the moon, both diligently pursuing their courses; and the night and the day hath he (also) made subject to you.
وَاللَّهُ جَعَلَ لَكُم مِّن بُيُوتِكُمْ سَكَنًا وَجَعَلَ لَكُم مِّن جُلُودِ الْأَنْعَامِ بُيُوتًا تَسْتَخِفُّونَهَا يَوْمَ ظَعْنِكُمْ وَيَوْمَ إِقَامَتِكُمْ ۙ وَمِنْ أَصْوَافِهَا وَأَوْبَارِهَا وَأَشْعَارِهَا أَثَاثًا وَمَتَاعًا إِلَىٰ حِين
It is Allah Who made your habitations homes of rest and quiet for you; and made for you, out of the skins of animals, (tents for) dwellings, which ye find so light (and handy) when ye travel and when ye stop (in your travels); and out of their wool, and their soft fibres (between wool and hair), and their hair, rich stuff and articles of convenience (to serve you) for a time.
وَاللَّهُ جَعَلَ لَكُم مِّمَّا خَلَقَ ظِلَالًا وَجَعَلَ لَكُم مِّنَ الْجِبَالِ أَكْنَانًا وَجَعَلَ لَكُمْ سَرَابِيلَ تَقِيكُمُ الْحَرَّ وَسَرَابِيلَ تَقِيكُم بَأْسَكُمْ ۚ كَذَٰلِكَ يُتِمُّ نِعْمَتَهُ عَلَيْكُمْ لَعَلَّكُمْ تُسْلِمُونَ
It is Allah Who made out of the things He created, some things to give you shade; of the hills He made some for your shelter; He made you garments to protect you from heat, and coats of mail to protect you from your (mutual) violence. Thus does He complete His favours on you, that ye may bow to His Will (in Islam).
Most of verses have explained about a lot of cases in detail and attention of creator are expressed in detail. Quran states
وَجَعَلْنَا اللَّيْلَ وَالنَّهَارَ آيَتَيْنِ ۖ فَمَحَوْنَا آيَةَ اللَّيْلِ وَجَعَلْنَا آيَةَ النَّهَارِ مُبْصِرَةً لِّتَبْتَغُوا فَضْلًا مِّن رَّبِّكُمْ وَلِتَعْلَمُوا عَدَدَ السِّنِينَ وَالْحِسَابَ ۚ وَكُلَّ شَيْءٍ فَصَّلْنَاهُ تَفْصِيلًا
We have made the Night and the Day as two (of Our) Signs: the Sign of the Night have We obscured, while the Sign of the Day We have made to enlighten you; that ye may seek bounty from your Lord, and that ye may know the number and count of the years: all things have We explained in detail.
وَآيَةٌ لَّهُمُ اللَّيْلُ نَسْلَخُ مِنْهُ النَّهَارَ فَإِذَا هُم مُّظْلِمُونَ
And a Sign for them is the Night: We withdraw therefrom the Day, and behold they are plunged in darkness.
وَالشَّمْسُ تَجْرِي لِمُسْتَقَرٍّ لَّهَا ۚ ذَٰلِكَ تَقْدِيرُ الْعَزِيزِ الْعَلِيمِ
And the sun runs his course for a period determined for him: that is the decree of (Him), the Exalted in Might, the All-Knowing.
وَالْقَمَرَ قَدَّرْنَاهُ مَنَازِلَ حَتَّىٰ عَادَ كَالْعُرْجُونِ الْقَدِيمِ
And the Moon,- We have measured for her mansions (to traverse) till she returns like the old (and withered) lower part of a date-stalk.
لَا الشَّمْسُ يَنبَغِي لَهَا أَن تُدْرِكَ الْقَمَرَ وَلَا اللَّيْلُ سَابِقُ النَّهَارِ ۚ وَكُلٌّ فِي فَلَكٍ يَسْبَحُونَ
It is not permitted to the Sun to catch up the Moon, nor can the Night outstrip the Day: Each (just) swims along in (its own) orbit (according to Law).
لْ أَرَأَيْتُمْ شُرَكَاءَكُمُ الَّذِينَ تَدْعُونَ مِن دُونِ اللَّهِ أَرُونِي مَاذَا خَلَقُوا مِنَ الْأَرْضِ أَمْ لَهُمْ شِرْكٌ فِي السَّمَاوَاتِ أَمْ آتَيْنَاهُمْ كِتَابًا فَهُمْ عَلَىٰ بَيِّنَتٍ مِّنْهُ ۚ بَلْ إِن يَعِدُ الظَّالِمُونَ بَعْضُهُم بَعْضًا إِلَّا غُرُورًا
Say: "Have ye seen (these) ´Partners´ of yours whom ye call upon besides Allah? Show Me what it is they have created in the (wide) earth. Or have they a share in the heavens? Or have We given them a Book from which they (can derive) clear (evidence)?- Nay, the wrong-doers promise each other nothing but delusions.
إِنَّ اللَّهَ يُمْسِكُ السَّمَاوَاتِ وَالْأَرْضَ أَن تَزُولَا ۚ وَلَئِن زَالَتَا إِنْ أَمْسَكَهُمَا مِنْ أَحَدٍ مِّن بَعْدِهِ ۚ إِنَّهُ كَانَ حَلِيمًا غَفُورً
It is Allah Who sustains the heavens and the earth, lest they cease (to function): and if they should fail, there is none - not one - can sustain them thereafter: Verily He is Most Forbearing, Oft-Forgiving.
وَهُوَ الَّذِي جَعَلَ لَكُمُ النُّجُومَ لِتَهْتَدُوا بِهَا فِي ظُلُمَاتِ الْبَرِّ وَالْبَحْرِ ۗ قَدْ فَصَّلْنَا الْآيَاتِ لِقَوْمٍ يَعْلَمُونَ
It is He Who maketh the stars (as beacons) for you, that ye may guide yourselves, with their help, through the dark spaces of land and sea: We detail Our signs for people who know.
فَلَا أُقْسِمُ بِمَوَاقِعِ النُّجُومِ
Furthermore I call to witness the setting of the Stars.
وَإِنَّهُ لَقَسَمٌ لَّوْ تَعْلَمُونَ عَظِيمٌ
And that is indeed a mighty adjuration if ye but knew.
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.
وَاتَّخَذُوا مِن دُونِهِ آلِهَةً لَّا يَخْلُقُونَ شَيْئًا وَهُمْ يُخْلَقُونَ وَلَا يَمْلِكُونَ لِأَنفُسِهِمْ ضَرًّا وَلَا نَفْعًا وَلَا يَمْلِكُونَ مَوْتًا وَلَا حَيَاةً وَلَا نُشُورًا
Yet have they taken, besides him, gods that can create nothing but are themselves created; that have no control of hurt or good to themselves; nor can they control death nor life nor resurrection.
There are a lot of comprehensive verses that refer to attention of God to creatures as Quran states
وَالْأَرْضَ مَدَدْنَاهَا وَأَلْقَيْنَا فِيهَا رَوَاسِيَ وَأَنبَتْنَا فِيهَا مِن كُلِّ شَيْءٍ مَّوْزُونٍ
And the earth We have spread out (like a carpet); set thereon mountains firm and immovable; and produced therein all kinds of things in due balance.
وَجَعَلْنَا لَكُمْ فِيهَا مَعَايِشَ وَمَن لَّسْتُمْ لَهُ بِرَازِقِينَ
And We have provided therein means of subsistence,- for you and for those for whose sustenance ye are not responsible.
وَإِن مِّن شَيْءٍ 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.
Attention of God to persons is infinite as Quran states
لَقَدْ خَلَقْنَا الْإِنسَانَ فِي أَحْسَنِ تَقْوِيمٍ
We have indeed created man in the best of moulds.
الرَّحْمَٰنُ
.(Allah) Most Gracious
عَلَّمَ الْقُرْآنَ
.It is He Who has taught the Qur´an
خَلَقَ الْإِنسَانَ
.He has created man
عَلَّمَهُ الْبَيَانَ
He has taught him speech (and intelligence).
إِنَّا هَدَيْنَاهُ السَّبِيلَ إِمَّا شَاكِرًا وَإِمَّا كَفُورًا
We showed him the Way: whether he be grateful or ungrateful (rests on his will).
وَاللَّهُ جَعَلَ لَكُم مِّنْ أَنفُسِكُمْ أَزْوَاجًا وَجَعَلَ لَكُم مِّنْ أَزْوَاجِكُم بَنِينَ وَحَفَدَةً وَرَزَقَكُم مِّنَ الطَّيِّبَاتِ ۚ أَفَبِالْبَاطِلِ يُؤْمِنُونَ وَبِنِعْمَتِ اللَّهِ هُمْ يَكْفُرُونَ
And Allah has made for you mates (and companions) of your own nature, and made for you, out of them, sons and daughters and grandchildren, and provided for you sustenance of the best: will they then believe in vain things, and be ungrateful for Allah´s favours?
وَيَعْبُدُونَ مِن دُونِ اللَّهِ مَا لَا يَمْلِكُ لَهُمْ رِزْقًا مِّنَ السَّمَاوَاتِ وَالْأَرْضِ شَيْئًا وَلَا يَسْتَطِيعُونَ
And worship others than Allah,- such as have no power of providing them, for sustenance, with anything in heavens or earth, and cannot possibly have such power?
God has remembered animals that help human in transportation, food and other uses. Quran states about tamed animals
وَإِنَّ لَكُمْ فِي الْأَنْعَامِ لَعِبْرَةً ۖ نُّسْقِيكُم مِّمَّا فِي بُطُونِهِ مِن بَيْنِ فَرْثٍ وَدَمٍ لَّبَنًا خَالِصًا سَائِغًا لِّلشَّارِبِينَ
And verily in cattle (too) will ye find an instructive sign. From what is within their bodies between excretions and blood, We produce, for your drink, milk, pure and agreeable to those who drink it.
وَمِن ثَمَرَاتِ النَّخِيلِ وَالْأَعْنَابِ تَتَّخِذُونَ مِنْهُ سَكَرًا وَرِزْقًا حَسَنًا ۗ إِنَّ فِي ذَٰلِكَ لَآيَةً لِّقَوْمٍ يَعْقِلُونَ
And from the fruit of the date-palm and the vine, ye get out wholesome drink and food: behold, in this also is a sign for those who are wise.
وَالْأَنْعَامَ خَلَقَهَا ۗ لَكُمْ فِيهَا دِفْءٌ وَمَنَافِعُ وَمِنْهَا تَأْكُلُونَ
And cattle He has created for you (men): from them ye derive warmth, and numerous benefits, and of their (meat) ye eat.
وَتَحْمِلُ أَثْقَالَكُمْ إِلَىٰ بَلَدٍ لَّمْ تَكُونُوا بَالِغِيهِ إِلَّا بِشِقِّ الْأَنفُسِ ۚ إِنَّ رَبَّكُمْ لَرَءُوفٌ رَّحِيمٌ
And they carry your heavy loads to lands that ye could not (otherwise) reach except with souls distressed: for your Lord is indeed Most Kind, Most Merciful.
وَالْخَيْلَ وَالْبِغَالَ وَالْحَمِيرَ لِتَرْكَبُوهَا وَزِينَةً ۚ وَيَخْلُقُ مَا لَا تَعْلَمُونَ
And (He has created) horses, mules, and donkeys, for you to ride and use for show; and He has created (other) things of which ye have no knowledge.
وَعَلَى اللَّهِ قَصْدُ السَّبِيلِ وَمِنْهَا جَائِرٌ ۚ وَلَوْ شَاءَ لَهَدَاكُمْ أَجْمَعِينَ
And unto Allah leads straight the Way, but there are ways that turn aside: if Allah had willed, He could have guided all of you.
Quran also states about other animals
وَأَوْحَىٰ رَبُّكَ إِلَى النَّحْلِ أَنِ اتَّخِذِي مِنَ الْجِبَالِ بُيُوتًا وَمِنَ الشَّجَرِ وَمِمَّا يَعْرِشُونَ
And thy Lord taught the Bee to build its cells in hills, on trees, and in (men´s) habitations.
Quran states about plants
وَهُوَ الَّذِي أَنزَلَ مِنَ السَّمَاءِ مَاءً فَأَخْرَجْنَا بِهِ نَبَاتَ كُلِّ شَيْءٍ فَأَخْرَجْنَا مِنْهُ خَضِرًا نُّخْرِجُ مِنْهُ حَبًّا مُّتَرَاكِبًا وَمِنَ النَّخْلِ مِن طَلْعِهَا قِنْوَانٌ دَانِيَةٌ وَجَنَّاتٍ مِّنْ أَعْنَابٍ وَالزَّيْتُونَ وَالرُّمَّانَ مُشْتَبِهًا وَغَيْرَ مُتَشَابِهٍ ۗ انظُرُوا إِلَىٰ ثَمَرِهِ إِذَا أَثْمَرَ وَيَنْعِهِ ۚ إِنَّ فِي ذَٰلِكُمْ لَآيَاتٍ لِّقَوْمٍ يُؤْمِنُونَ
It is He Who sendeth down rain from the skies: with it We produce vegetation of all kinds: from some We produce green (crops), out of which We produce grain, heaped up (at harvest); out of the date-palm and its sheaths (or spathes) (come) clusters of dates hanging low and near: and (then there are) gardens of grapes, and olives, and pomegranates, each similar (in kind) yet different (in variety): when they begin to bear fruit, feast your eyes with the fruit and the ripeness thereof. Behold! in these things there are signs for people who believe.
