Source and approach of revelation

In spite of the fact that Quran is divine revelation and has special order, there is specific relationship among some Surahs. For example, Surahs that start with '' Ha Mim'' share same content. These Surahs are about revelation, revelation descending, revelation receiving and content of revelation. Quran states
وَتَرَىٰ كُلَّ أُمَّةٍ جَاثِيَةً ۚ كُلُّ أُمَّةٍ تُدْعَىٰ إِلَىٰ كِتَابِهَا الْيَوْمَ تُجْزَوْنَ مَا كُنتُمْ تَعْمَلُونَ
And thou wilt see every sect bowing the knee: Every sect will be called to its Record: "This Day shall ye be recompensed for all that ye did.
Quran states about a special group in the doomsday
لَا يَحْزُنُهُمُ الْفَزَعُ الْأَكْبَرُ وَتَتَلَقَّاهُمُ الْمَلَائِكَةُ هَٰذَا يَوْمُكُمُ الَّذِي كُنتُمْ تُوعَدُونَ
The Great Terror will bring them no grief: but the angels will meet them (with mutual greetings): "This is your Day,- (the Day) that ye were promised.
إِنَّ فِي السَّمَاوَاتِ وَالْأَرْضِ لَآيَاتٍ لِّلْمُؤْمِنِينَ
Verily in the heavens and the earth, are Signs for those who believe. Imam Sajad (peace be upon him) states
'' رأیت أن طلب المحتاج الی المحتاج سفه من رأیه و ضلة من عقله''
If persons think about themselves and recognize their needs, they will understand that their needs will be met by a needless creature.
وَفِي خَلْقِكُمْ وَمَا يَبُثُّ مِن دَابَّةٍ آيَاتٌ لِّقَوْمٍ يُوقِنُونَ
And in the creation of yourselves and the fact that animals are scattered (through the earth), are Signs for those of assured Faith.
وَفِي خَلْقِكُمْ وَمَا يَبُثُّ مِن دَابَّةٍ آيَاتٌ لِّقَوْمٍ يُوقِنُونَ
And in the creation of yourselves and the fact that animals are scattered (through the earth), are Signs for those of assured Faith.
وَاخْتِلَافِ اللَّيْلِ وَالنَّهَارِ وَمَا أَنزَلَ اللَّهُ مِنَ السَّمَاءِ مِن رِّزْقٍ فَأَحْيَا بِهِ الْأَرْضَ بَعْدَ مَوْتِهَا وَتَصْرِيفِ الرِّيَاحِ آيَاتٌ لِّقَوْمٍ يَعْقِلُونَ
And in the alternation of Night and Day, and the fact that Allah sends down Sustenance from the sky, and revives therewith the earth after its death, and in the change of the winds,- are Signs for those that are wise.
The system of the world is system of affection and association. Persons that have religious light think about weak persons. Quran states
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).
Quran states
المر ۚ تِلْكَ آيَاتُ الْكِتَابِ ۗ وَالَّذِي أُنزِلَ إِلَيْكَ مِن رَّبِّكَ الْحَقُّ وَلَٰكِنَّ أَكْثَرَ النَّاسِ لَا يُؤْمِنُونَ
A.L.M.R. These are the signs (or verses) of the Book: that which hath been revealed unto thee from thy Lord is the Truth; but most men believe not.
اللَّهُ الَّذِي رَفَعَ السَّمَاوَاتِ بِغَيْرِ عَمَدٍ تَرَوْنَهَا ۖ ثُمَّ اسْتَوَىٰ عَلَى الْعَرْشِ ۖ وَسَخَّرَ الشَّمْسَ وَالْقَمَرَ ۖ كُلٌّ يَجْرِي لِأَجَلٍ مُّسَمًّى ۚ يُدَبِّرُ الْأَمْرَ يُفَصِّلُ الْآيَاتِ لَعَلَّكُم بِلِقَاءِ رَبِّكُمْ تُوقِنُونَ
Allah is He Who raised the heavens without any pillars that ye can see; is firmly established on the throne (of authority); He has subjected the sun and the moon (to his Law)! Each one runs (its course) for a term appointed. He doth regulate all affairs, explaining the signs in detail, that ye may believe with certainty in the meeting with your Lord.
وَهُوَ الَّذِي مَدَّ الْأَرْضَ وَجَعَلَ فِيهَا رَوَاسِيَ وَأَنْهَارًا ۖ وَمِن كُلِّ الثَّمَرَاتِ جَعَلَ فِيهَا زَوْجَيْنِ اثْنَيْنِ ۖ يُغْشِي اللَّيْلَ النَّهَارَ ۚ إِنَّ فِي ذَٰلِكَ لَآيَاتٍ لِّقَوْمٍ يَتَفَكَّرُونَ
And it is He who spread out the earth, and set thereon mountains standing firm and (flowing) rivers: and fruit of every kind He made in pairs, two and two: He draweth the night as a veil o´er the Day. Behold, verily in these things there are signs for those who consider.
وَفِي الْأَرْضِ قِطَعٌ مُّتَجَاوِرَاتٌ وَجَنَّاتٌ مِّنْ أَعْنَابٍ وَزَرْعٌ وَنَخِيلٌ صِنْوَانٌ وَغَيْرُ صِنْوَانٍ يُسْقَىٰ بِمَاءٍ وَاحِدٍ وَنُفَضِّلُ بَعْضَهَا عَلَىٰ بَعْضٍ فِي الْأُكُلِ ۚ إِنَّ فِي ذَٰلِكَ لَآيَاتٍ لِّقَوْمٍ يَعْقِلُونَ
And in the earth are tracts (diverse though) neighbouring, and gardens of vines and fields sown with corn, and palm trees - growing out of single roots or otherwise: watered with the same water, yet some of them We make more excellent than others to eat. Behold, verily in these things there are signs for those who understand.
تِلْكَ آيَاتُ اللَّهِ نَتْلُوهَا عَلَيْكَ بِالْحَقِّ ۖ فَبِأَيِّ حَدِيثٍ بَعْدَ اللَّهِ وَآيَاتِهِ يُؤْمِنُونَ
Such are the Signs of Allah, which We rehearse to thee in Truth; then in what exposition will they believe after (rejecting) Allah and His Signs.
وَيْلٌ لِّكُلِّ أَفَّاكٍ أَثِيمٍ
Woe to each sinful dealer in Falsehoods.
يَسْمَعُ آيَاتِ اللَّهِ تُتْلَىٰ عَلَيْهِ ثُمَّ يُصِرُّ مُسْتَكْبِرًا كَأَن لَّمْ يَسْمَعْهَا ۖ فَبَشِّرْهُ بِعَذَابٍ أَلِيمٍ
He hears the Signs of Allah rehearsed to him, yet is obstinate and lofty, as if he had not heard them: then announce to him a Penalty Grievous.
Quran states that tyrant persons endure the worst kind of torturing;
وَإِذَا عَلِمَ مِنْ آيَاتِنَا شَيْئًا اتَّخَذَهَا هُزُوًا ۚ أُولَٰئِكَ لَهُمْ عَذَابٌ مُّهِينٌ
And when he learns something of Our Signs, he takes them in jest: for such there will be a humiliating Penalty.
Quran states
إِنَّ الَّذِينَ كَفَرُوا بِآيَاتِنَا سَوْفَ نُصْلِيهِمْ نَارًا كُلَّمَا نَضِجَتْ جُلُودُهُم بَدَّلْنَاهُمْ جُلُودًا غَيْرَهَا لِيَذُوقُوا الْعَذَابَ ۗ إِنَّ اللَّهَ كَانَ عَزِيزًا حَكِيمًا
Those who reject our Signs, We shall soon cast into the Fire: as often as their skins are roasted through, We shall change them for fresh skins, that they may taste the penalty: for Allah is Exalted in Power, Wise.
حُرِّمَتْ عَلَيْكُمْ أُمَّهَاتُكُمْ وَبَنَاتُكُمْ وَأَخَوَاتُكُمْ وَعَمَّاتُكُمْ وَخَالَاتُكُمْ وَبَنَاتُ الْأَخِ وَبَنَاتُ الْأُخْتِ وَأُمَّهَاتُكُمُ اللَّاتِي أَرْضَعْنَكُمْ وَأَخَوَاتُكُم مِّنَ الرَّضَاعَةِ وَأُمَّهَاتُ نِسَائِكُمْ وَرَبَائِبُكُمُ اللَّاتِي فِي حُجُورِكُم مِّن نِّسَائِكُمُ اللَّاتِي دَخَلْتُم بِهِنَّ فَإِن لَّمْ تَكُونُوا دَخَلْتُم بِهِنَّ فَلَا جُنَاحَ عَلَيْكُمْ وَحَلَائِلُ أَبْنَائِكُمُ الَّذِينَ مِنْ أَصْلَابِكُمْ وَأَن تَجْمَعُوا بَيْنَ الْأُخْتَيْنِ إِلَّا مَا قَدْ سَلَفَ ۗ إِنَّ اللَّهَ كَانَ غَفُورًا رَّحِيمًا
Prohibited to you (For marriage) are:- Your mothers, daughters, sisters; father´s sisters, Mother´s sisters; brother´s daughters, sister´s daughters; foster-mothers (Who gave you suck), foster-sisters; your wives´ mothers; your step-daughters under your guardianship, born of your wives to whom ye have gone in,- no prohibition if ye have not gone in;- (Those who have been) wives of your sons proceeding from your loins; and two sisters in wedlock at one and the same time, except for what is past; for Allah is Oft-forgiving, Most Merciful.
وَمَن لَّمْ يَسْتَطِعْ مِنكُمْ طَوْلًا أَن يَنكِحَ الْمُحْصَنَاتِ الْمُؤْمِنَاتِ فَمِن مَّا مَلَكَتْ أَيْمَانُكُم مِّن فَتَيَاتِكُمُ الْمُؤْمِنَاتِ ۚ وَاللَّهُ أَعْلَمُ بِإِيمَانِكُم ۚ بَعْضُكُم مِّن بَعْضٍ ۚ فَانكِحُوهُنَّ بِإِذْنِ أَهْلِهِنَّ وَآتُوهُنَّ أُجُورَهُنَّ بِالْمَعْرُوفِ مُحْصَنَاتٍ غَيْرَ مُسَافِحَاتٍ وَلَا مُتَّخِذَاتِ أَخْدَانٍ ۚ فَإِذَا أُحْصِنَّ فَإِنْ أَتَيْنَ بِفَاحِشَةٍ فَعَلَيْهِنَّ نِصْفُ مَا عَلَى الْمُحْصَنَاتِ مِنَ الْعَذَابِ ۚ ذَٰلِكَ لِمَنْ خَشِيَ الْعَنَتَ مِنكُمْ ۚ وَأَن تَصْبِرُوا خَيْرٌ لَّكُمْ ۗ وَاللَّهُ غَفُورٌ رَّحِيمٌ
If any of you have not the means wherewith to wed free believing women, they may wed believing girls from among those whom your right hands possess: And Allah hath full knowledge about your faith. Ye are one from another: Wed them with the leave of their owners, and give them their dowers, according to what is reasonable: They should be chaste, not lustful, nor taking paramours: when they are taken in wedlock, if they fall into shame, their punishment is half that for free women. This (permission) is for those among you who fear sin; but it is better for you that ye practise self-restraint. And Allah is Oft-forgiving, Most Merciful.
مِّنَ الَّذِينَ هَادُوا يُحَرِّفُونَ الْكَلِمَ عَن مَّوَاضِعِهِ وَيَقُولُونَ سَمِعْنَا وَعَصَيْنَا وَاسْمَعْ غَيْرَ مُسْمَعٍ وَرَاعِنَا لَيًّا بِأَلْسِنَتِهِمْ وَطَعْنًا فِي الدِّينِ ۚ وَلَوْ أَنَّهُمْ قَالُوا سَمِعْنَا وَأَطَعْنَا وَاسْمَعْ وَانظُرْنَا لَكَانَ خَيْرًا لَّهُمْ وَأَقْوَمَ وَلَٰكِن لَّعَنَهُمُ اللَّهُ بِكُفْرِهِمْ فَلَا يُؤْمِنُونَ إِلَّا قَلِيلًا
Of the Jews there are those who displace words from their (right) places, and say: "We hear and we disobey"; and "Hear what is not Heard"; and "Ra´ina"; with a twist of their tongues and a slander to Faith. If only they had said: "What hear and we obey"; and "Do hear"; and "Do look at us"; it would have been better for them, and more proper; but Allah hath cursed them for their Unbelief; and but few of them will believe.
وَإِذَا جَاءَهُمْ أَمْرٌ مِّنَ الْأَمْنِ أَوِ الْخَوْفِ أَذَاعُوا بِهِ ۖ وَلَوْ رَدُّوهُ إِلَى الرَّسُولِ وَإِلَىٰ أُولِي الْأَمْرِ مِنْهُمْ لَعَلِمَهُ الَّذِينَ يَسْتَنبِطُونَهُ مِنْهُمْ ۗ وَلَوْلَا فَضْلُ اللَّهِ عَلَيْكُمْ وَرَحْمَتُهُ لَاتَّبَعْتُمُ الشَّيْطَانَ إِلَّا قَلِيلًا
When there comes to them some matter touching (Public) safety or fear, they divulge it. If they had only referred it to the Messenger, or to those charged with authority among them, the proper investigators would have Tested it from them (direct). Were it not for the Grace and Mercy of Allah unto you, all but a few of you would have fallen into the clutches of Satan.
إِلَّا الَّذِينَ يَصِلُونَ إِلَىٰ قَوْمٍ بَيْنَكُمْ وَبَيْنَهُم مِّيثَاقٌ أَوْ جَاءُوكُمْ حَصِرَتْ صُدُورُهُمْ أَن يُقَاتِلُوكُمْ أَوْ يُقَاتِلُوا قَوْمَهُمْ ۚ وَلَوْ شَاءَ اللَّهُ لَسَلَّطَهُمْ عَلَيْكُمْ فَلَقَاتَلُوكُمْ ۚ فَإِنِ اعْتَزَلُوكُمْ فَلَمْ يُقَاتِلُوكُمْ وَأَلْقَوْا إِلَيْكُمُ السَّلَمَ فَمَا جَعَلَ اللَّهُ لَكُمْ عَلَيْهِمْ سَبِيلًا
Except those who join a group between whom and you there is a treaty (of peace), or those who approach you with hearts restraining them from fighting you as well as fighting their own people. If Allah had pleased, He could have given them power over you, and they would have fought you: Therefore if they withdraw from you but fight you not, and (instead) send you (Guarantees of) peace, then Allah Hath opened no way for you (to war against them.
وَمَا كَانَ لِمُؤْمِنٍ أَن يَقْتُلَ مُؤْمِنًا إِلَّا خَطَأً ۚ وَمَن قَتَلَ مُؤْمِنًا خَطَأً فَتَحْرِيرُ رَقَبَةٍ مُّؤْمِنَةٍ وَدِيَةٌ مُّسَلَّمَةٌ إِلَىٰ أَهْلِهِ إِلَّا أَن يَصَّدَّقُوا ۚ فَإِن كَانَ مِن قَوْمٍ عَدُوٍّ لَّكُمْ وَهُوَ مُؤْمِنٌ فَتَحْرِيرُ رَقَبَةٍ مُّؤْمِنَةٍ ۖ وَإِن كَانَ مِن قَوْمٍ بَيْنَكُمْ وَبَيْنَهُم مِّيثَاقٌ فَدِيَةٌ مُّسَلَّمَةٌ إِلَىٰ أَهْلِهِ وَتَحْرِيرُ رَقَبَةٍ مُّؤْمِنَةٍ ۖ فَمَن لَّمْ يَجِدْ فَصِيَامُ شَهْرَيْنِ مُتَتَابِعَيْنِ تَوْبَةً مِّنَ اللَّهِ ۗ وَكَانَ اللَّهُ عَلِيمًا حَكِيمًا
Never should a believer kill a believer; but (If it so happens) by mistake, (Compensation is due): If one (so) kills a believer, it is ordained that he should free a believing slave, and pay compensation to the deceased´s family, unless they remit it freely. If the deceased belonged to a people at war with you, and he was a believer, the freeing of a believing slave (Is enough). If he belonged to a people with whom ye have treaty of Mutual alliance, compensation should be paid to his family, and a believing slave be freed. For those who find this beyond their means, (is prescribed) a fast for two months running: by way of repentance to Allah: for Allah hath all knowledge and all wisdom.
يَا أَيُّهَا الَّذِينَ آمَنُوا إِذَا ضَرَبْتُمْ فِي سَبِيلِ اللَّهِ فَتَبَيَّنُوا وَلَا تَقُولُوا لِمَنْ أَلْقَىٰ إِلَيْكُمُ السَّلَامَ لَسْتَ مُؤْمِنًا تَبْتَغُونَ عَرَضَ الْحَيَاةِ الدُّنْيَا فَعِندَ اللَّهِ مَغَانِمُ كَثِيرَةٌ ۚ كَذَٰلِكَ كُنتُم مِّن قَبْلُ فَمَنَّ اللَّهُ عَلَيْكُمْ فَتَبَيَّنُوا ۚ إِنَّ اللَّهَ كَانَ بِمَا تَعْمَلُونَ خَبِيرًا
O ye who believe! When ye go abroad in the cause of Allah, investigate carefully, and say not to any one who offers you a salutation: "Thou art none of a believer!" Coveting the perishable goods of this life: with Allah are profits and spoils abundant. Even thus were ye yourselves before, till Allah conferred on you His favours: Therefore carefully investigate. For Allah is well aware of all that ye do.
لَّا يَسْتَوِي الْقَاعِدُونَ مِنَ الْمُؤْمِنِينَ غَيْرُ أُولِي الضَّرَرِ وَالْمُجَاهِدُونَ فِي سَبِيلِ اللَّهِ بِأَمْوَالِهِمْ وَأَنفُسِهِمْ ۚ فَضَّلَ اللَّهُ الْمُجَاهِدِينَ بِأَمْوَالِهِمْ وَأَنفُسِهِمْ عَلَى الْقَاعِدِينَ دَرَجَةً ۚ وَكُلًّا وَعَدَ اللَّهُ الْحُسْنَىٰ ۚ وَفَضَّلَ اللَّهُ الْمُجَاهِدِينَ عَلَى الْقَاعِدِينَ أَجْرًا عَظِيمًا
Not equal are those believers who sit (at home) and receive no hurt, and those who strive and fight in the cause of Allah with their goods and their persons. Allah hath granted a grade higher to those who strive and fight with their goods and persons than to those who sit (at home). Unto all (in Faith) Hath Allah promised good: But those who strive and fight Hath He distinguished above those who sit (at home) by a special reward.
