Divine messages and rational thought of ways of God recognition

Monotheism has ranks and Quran is light and guidance and it is not a philosophical book. Moreover, it presents rational reasons.
Quran states
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.
God states to the messenger of God (peace of Allah be upon him and his descendants)
قُلْ إِنَّنِي هَدَانِي رَبِّي إِلَىٰ صِرَاطٍ مُّسْتَقِيمٍ دِينًا قِيَمًا مِّلَّةَ إِبْرَاهِيمَ حَنِيفًا ۚ وَمَا كَانَ مِنَ الْمُشْرِكِينَ
Say: "Verily, my Lord hath guided me to a way that is straight,- a religion of right,- the path (trod) by Abraham the true in Faith, and he (certainly) joined not gods with Allah.
Quran states
قُلْ إِنَّنِي هَدَانِي رَبِّي إِلَىٰ صِرَاطٍ مُّسْتَقِيمٍ دِينًا قِيَمًا مِّلَّةَ إِبْرَاهِيمَ حَنِيفًا ۚ وَمَا كَانَ مِنَ الْمُشْرِكِينَ
Say: "Verily, my Lord hath guided me to a way that is straight,- a religion of right,- the path (trod) by Abraham the true in Faith, and he (certainly) joined not gods with Allah.
قُلْ إِنَّ صَلَاتِي وَنُسُكِي وَمَحْيَايَ وَمَمَاتِي لِلَّهِ رَبِّ الْعَالَمِينَ
Say: "Truly, my prayer and my service of sacrifice, my life and my death, are (all) for Allah, the Cherisher of the Worlds.
لَا شَرِيكَ لَهُ ۖ وَبِذَٰلِكَ أُمِرْتُ وَأَنَا أَوَّلُ الْمُسْلِمِينَ
No partner hath He: this am I commanded, and I am the first of those who bow to His will.
Quran states about the whole system before appearance of human life;
قُلْ أَغَيْرَ اللَّهِ أَبْغِي رَبًّا وَهُوَ رَبُّ كُلِّ شَيْءٍ ۚ وَلَا تَكْسِبُ كُلُّ نَفْسٍ إِلَّا عَلَيْهَا ۚ وَلَا تَزِرُ وَازِرَةٌ وِزْرَ أُخْرَىٰ ۚ ثُمَّ إِلَىٰ رَبِّكُم مَّرْجِعُكُمْ فَيُنَبِّئُكُم بِمَا كُنتُمْ فِيهِ تَخْتَلِفُونَ
Say: "Shall I seek for (my) Cherisher other than Allah, when He is the Cherisher of all things (that exist)? Every soul draws the meed of its acts on none but itself: no bearer of burdens can bear of burdens can bear the burden of another. Your goal in the end is towards Allah: He will tell you the truth of the things wherein ye disputed.
All creatures need God as Quran states
قُلْ أَغَيْرَ اللَّهِ أَتَّخِذُ وَلِيًّا فَاطِرِ السَّمَاوَاتِ وَالْأَرْضِ وَهُوَ يُطْعِمُ وَلَا يُطْعَمُ ۗ قُلْ إِنِّي أُمِرْتُ أَنْ أَكُونَ أَوَّلَ مَنْ أَسْلَمَ ۖ وَلَا تَكُونَنَّ مِنَ الْمُشْرِكِينَ
Say: "Shall I take for my protector any other than Allah, the Maker of the heavens and the earth? And He it is that feedeth but is not fed." Say: "Nay! but I am commanded to be the first of those who bow to Allah (in Islam), and be not thou of the company of those who join gods with Allah.
God has created everything as Quran states
قُلْ أَغَيْرَ اللَّهِ أَبْغِي رَبًّا وَهُوَ رَبُّ كُلِّ شَيْءٍ ۚ وَلَا تَكْسِبُ كُلُّ نَفْسٍ إِلَّا عَلَيْهَا ۚ وَلَا تَزِرُ وَازِرَةٌ وِزْرَ أُخْرَىٰ ۚ ثُمَّ إِلَىٰ رَبِّكُم مَّرْجِعُكُمْ فَيُنَبِّئُكُم بِمَا كُنتُمْ فِيهِ تَخْتَلِفُونَ
Say: "Shall I seek for (my) Cherisher other than Allah, when He is the Cherisher of all things (that exist)? Every soul draws the meed of its acts on none but itself: no bearer of burdens can bear of burdens can bear the burden of another. Your goal in the end is towards Allah: He will tell you the truth of the things wherein ye disputed.
Quran states
أَمْ حَسِبَ الَّذِينَ اجْتَرَحُوا السَّيِّئَاتِ أَن نَّجْعَلَهُمْ كَالَّذِينَ آمَنُوا وَعَمِلُوا الصَّالِحَاتِ سَوَاءً مَّحْيَاهُمْ وَمَمَاتُهُمْ ۚ سَاءَ مَا يَحْكُمُونَ
What! Do those who seek after evil ways think that We shall hold them equal with those who believe and do righteous deeds,- that equal will be their life and their death? Ill is the judgment that they make.
قُلْ أَغَيْرَ اللَّهِ أَبْغِي رَبًّا وَهُوَ رَبُّ كُلِّ شَيْءٍ ۚ وَلَا تَكْسِبُ كُلُّ نَفْسٍ إِلَّا عَلَيْهَا ۚ وَلَا تَزِرُ وَازِرَةٌ وِزْرَ أُخْرَىٰ ۚ ثُمَّ إِلَىٰ رَبِّكُم مَّرْجِعُكُمْ فَيُنَبِّئُكُم بِمَا كُنتُمْ فِيهِ تَخْتَلِفُونَ
Say: "Shall I seek for (my) Cherisher other than Allah, when He is the Cherisher of all things (that exist)? Every soul draws the meed of its acts on none but itself: no bearer of burdens can bear of burdens can bear the burden of another. Your goal in the end is towards Allah: He will tell you the truth of the things wherein ye disputed.
Quran states about day of reality
سَنُرِيهِمْ آيَاتِنَا فِي الْآفَاقِ وَفِي أَنفُسِهِمْ حَتَّىٰ يَتَبَيَّنَ لَهُمْ أَنَّهُ الْحَقُّ ۗ أَوَلَمْ يَكْفِ بِرَبِّكَ أَنَّهُ عَلَىٰ كُلِّ شَيْءٍ شَهِيدٌ
Soon will We show them our Signs in the (furthest) regions (of the earth), and in their own souls, until it becomes manifest to them that this is the Truth. Is it not enough that thy Lord doth witness all things.
يَوْمَئِذٍ يَوَدُّ الَّذِينَ كَفَرُوا وَعَصَوُا الرَّسُولَ لَوْ تُسَوَّىٰ بِهِمُ الْأَرْضُ وَلَا يَكْتُمُونَ اللَّهَ حَدِيثًا
On that day those who reject Faith and disobey the messenger will wish that the earth Were made one with them: But never will they hide a single fact from Allah.
وَهُوَ الَّذِي جَعَلَكُمْ خَلَائِفَ الْأَرْضِ وَرَفَعَ بَعْضَكُمْ فَوْقَ بَعْضٍ دَرَجَاتٍ لِّيَبْلُوَكُمْ فِي مَا آتَاكُمْ ۗ إِنَّ رَبَّكَ سَرِيعُ الْعِقَابِ وَإِنَّهُ لَغَفُورٌ رَّحِيمٌ
It is He Who hath made you (His) agents, inheritors of the earth: He hath raised you in ranks, some above others: that He may try you in the gifts He hath given you: for thy Lord is quick in punishment: yet He is indeed Oft-forgiving, Most Merciful.
God has considers differences in order to establish order
يَا أَيُّهَا النَّاسُ إِنَّا خَلَقْنَاكُم مِّن ذَكَرٍ وَأُنثَىٰ وَجَعَلْنَاكُمْ شُعُوبًا وَقَبَائِلَ لِتَعَارَفُوا ۚ إِنَّ أَكْرَمَكُمْ عِندَ اللَّهِ أَتْقَاكُمْ ۚ إِنَّ اللَّهَ عَلِيمٌ خَبِيرٌ
O mankind! We created you from a single (pair) of a male and a female, and made you into nations and tribes, that ye may know each other (not that ye may despise (each other). Verily the most honoured of you in the sight of Allah is (he who is) the most righteous of you. And Allah has full knowledge and is well acquainted (with all things).
أَهُمْ يَقْسِمُونَ رَحْمَتَ رَبِّكَ ۚ نَحْنُ قَسَمْنَا بَيْنَهُم مَّعِيشَتَهُمْ فِي الْحَيَاةِ الدُّنْيَا ۚ وَرَفَعْنَا بَعْضَهُمْ فَوْقَ بَعْضٍ دَرَجَاتٍ لِّيَتَّخِذَ بَعْضُهُم بَعْضًا سُخْرِيًّا ۗ وَرَحْمَتُ رَبِّكَ خَيْرٌ مِّمَّا يَجْمَعُونَ
Is it they who would portion out the Mercy of thy Lord? It is We Who portion out between them their livelihood in the life of this world: and We raise some of them above others in ranks, so that some may command work from others. But the Mercy of thy Lord is better than the (wealth) which they amass.
Quran states about monotheism of God
وَهُوَ الَّذِي جَعَلَكُمْ خَلَائِفَ الْأَرْضِ وَرَفَعَ بَعْضَكُمْ فَوْقَ بَعْضٍ دَرَجَاتٍ لِّيَبْلُوَكُمْ فِي مَا آتَاكُمْ ۗ إِنَّ رَبَّكَ سَرِيعُ الْعِقَابِ وَإِنَّهُ لَغَفُورٌ رَّحِيمٌ
It is He Who hath made you (His) agents, inheritors of the earth: He hath raised you in ranks, some above others: that He may try you in the gifts He hath given you: for thy Lord is quick in punishment: yet He is indeed Oft-forgiving, Most Merciful.
Quran states creation of the world
مَا خَلَقْنَا السَّمَاوَاتِ وَالْأَرْضَ وَمَا بَيْنَهُمَا إِلَّا بِالْحَقِّ وَأَجَلٍ مُّسَمًّى ۚ وَالَّذِينَ كَفَرُوا عَمَّا أُنذِرُوا مُعْرِضُونَ
We created not the heavens and the earth and all between them but for just ends, and for a Term Appointed: But those who reject Faith turn away from that whereof they are warned.
Quran states
مَا خَلَقْنَا السَّمَاوَاتِ وَالْأَرْضَ وَمَا بَيْنَهُمَا إِلَّا بِالْحَقِّ وَأَجَلٍ مُّسَمًّى ۚ وَالَّذِينَ كَفَرُوا عَمَّا أُنذِرُوا مُعْرِضُونَ
We created not the heavens and the earth and all between them but for just ends, and for a Term Appointed: But those who reject Faith turn away from that whereof they are warned.
قُلْ أَرَأَيْتُم مَّا تَدْعُونَ مِن دُونِ اللَّهِ أَرُونِي مَاذَا خَلَقُوا مِنَ الْأَرْضِ أَمْ لَهُمْ شِرْكٌ فِي السَّمَاوَاتِ ۖ ائْتُونِي بِكِتَابٍ مِّن قَبْلِ هَٰذَا أَوْ أَثَارَةٍ مِّنْ عِلْمٍ إِن كُنتُمْ صَادِقِينَ
Say: "Do ye see what it is ye invoke besides Allah? Show me what it is they have created on earth, or have they a share in the heavens bring me a book (revealed) before this, or any remnant of knowledge (ye may have), if ye are telling the truth.
Quran states about story of Qarun
تْلُو عَلَيْكَ مِن نَّبَإِ مُوسَىٰ وَفِرْعَوْنَ بِالْحَقِّ لِقَوْمٍ يُؤْمِنُونَ
We rehearse to thee some of the story of Moses and Pharaoh in Truth, for people who believe.
إِنَّ فِرْعَوْنَ عَلَا فِي الْأَرْضِ وَجَعَلَ أَهْلَهَا شِيَعًا يَسْتَضْعِفُ طَائِفَةً مِّنْهُمْ يُذَبِّحُ أَبْنَاءَهُمْ وَيَسْتَحْيِي نِسَاءَهُمْ ۚ إِنَّهُ كَانَ مِنَ الْمُفْسِدِينَ
Truly Pharaoh elated himself in the land and broke up its people into sections, depressing a small group among them: their sons he slew, but he kept alive their females: for he was indeed a maker of mischief.
Quran states
مَا خَلَقْنَا السَّمَاوَاتِ وَالْأَرْضَ وَمَا بَيْنَهُمَا إِلَّا بِالْحَقِّ وَأَجَلٍ مُّسَمًّى ۚ وَالَّذِينَ كَفَرُوا عَمَّا أُنذِرُوا مُعْرِضُونَ
We created not the heavens and the earth and all between them but for just ends, and for a Term Appointed: But those who reject Faith turn away from that whereof they are warned.
Quran states about the story of Qarun
نَّ قَارُونَ كَانَ مِن قَوْمِ مُوسَىٰ فَبَغَىٰ عَلَيْهِمْ ۖ وَآتَيْنَاهُ مِنَ الْكُنُوزِ مَا إِنَّ مَفَاتِحَهُ لَتَنُوءُ بِالْعُصْبَةِ أُولِي الْقُوَّةِ إِذْ قَالَ لَهُ قَوْمُهُ لَا تَفْرَحْ ۖ إِنَّ اللَّهَ لَا يُحِبُّ الْفَرِحِينَ
Qarun was doubtless, of the people of Moses; but he acted insolently towards them: such were the treasures We had bestowed on him that their very keys would have been a burden to a body of strong men, behold, his people said to him: "Exult not, for Allah loveth not those who exult (in riches).
وَابْتَغِ فِيمَا آتَاكَ اللَّهُ الدَّارَ الْآخِرَةَ ۖ وَلَا تَنسَ نَصِيبَكَ مِنَ الدُّنْيَا ۖ وَأَحْسِن كَمَا أَحْسَنَ اللَّهُ إِلَيْكَ ۖ وَلَا تَبْغِ الْفَسَادَ فِي الْأَرْضِ ۖ إِنَّ اللَّهَ لَا يُحِبُّ الْمُفْسِدِينَ
But seek, with the (wealth) which Allah has bestowed on thee, the Home of the Hereafter, nor forget thy portion in this world: but do thou good, as Allah has been good to thee, and seek not (occasions for) mischief in the land: for Allah loves not those who do mischief.
قَالَ إِنَّمَا أُوتِيتُهُ عَلَىٰ عِلْمٍ عِندِي ۚ أَوَلَمْ يَعْلَمْ أَنَّ اللَّهَ قَدْ أَهْلَكَ مِن قَبْلِهِ مِنَ الْقُرُونِ مَنْ هُوَ أَشَدُّ مِنْهُ قُوَّةً وَأَكْثَرُ جَمْعًا ۚ وَلَا يُسْأَلُ عَن ذُنُوبِهِمُ الْمُجْرِمُونَ
He said: "This has been given to me because of a certain knowledge which I have." Did he not know that Allah had destroyed, before him, (whole) generations,- which were superior to him in strength and greater in the amount (of riches) they had collected? but the wicked are not called (immediately) to account for their sins.
Quran states
وَمَا بِكُم مِّن نِّعْمَةٍ فَمِنَ اللَّهِ ۖ ثُمَّ إِذَا مَسَّكُمُ الضُّرُّ فَإِلَيْهِ تَجْأَرُونَ
And ye have no good thing but is from Allah: and moreover, when ye are touched by distress, unto Him ye cry with groans.
فَخَسَفْنَا بِهِ وَبِدَارِهِ الْأَرْضَ فَمَا كَانَ لَهُ مِن فِئَةٍ يَنصُرُونَهُ مِن دُونِ اللَّهِ وَمَا كَانَ مِنَ الْمُنتَصِرِينَ
Then We caused the earth to swallow up him and his house; and he had not (the least little) party to help him against Allah, nor could he defend himself.
Logic of unbelievers and idol worshippers has no rational root as Quran states
وَمَا آتَيْنَاهُم مِّن كُتُبٍ يَدْرُسُونَهَا ۖ وَمَا أَرْسَلْنَا إِلَيْهِمْ قَبْلَكَ مِن نَّذِيرٍ
But We had not given them Books which they could study, nor sent messengers to them before thee as Warners.
وَكَذَّبَ الَّذِينَ مِن قَبْلِهِمْ وَمَا بَلَغُوا مِعْشَارَ مَا آتَيْنَاهُمْ فَكَذَّبُوا رُسُلِي ۖ فَكَيْفَ كَانَ نَكِيرِ
And their predecessors rejected (the Truth); these have not received a tenth of what We had granted to those: yet when they rejected My messengers, how (terrible) was My rejection (of them).
وَمَنْ أَظْلَمُ مِمَّن ذُكِّرَ بِآيَاتِ رَبِّهِ ثُمَّ أَعْرَضَ عَنْهَا ۚ إِنَّا مِنَ الْمُجْرِمِينَ مُنتَقِمُونَ
And who does more wrong than one to whom are recited the Signs of his Lord, and who then turns away therefrom? Verily from those who transgress We shall exact (due) Retribution.
