The word ''verse'' in Quran

Ragheb says '' verse is each remark of Quran''. It is also said '' each sentence that expresses a rule is verse''. There is no question that Ragheb refers unity of topic in this definition because a verse is enough to study and express, some of them need some verses and still others need a Surah.
Each thing has outer appearance and it is possible to understand its inner through it. Sometimes, some signs refer to reality and nature of things and their recognition has permanent relationship with whatever is not understood from their appearance. Therefore, if a person understands signs with his or her eyes, he or she will understand its nature prudently.
Meaning of sign includes reasons and there are a lot of verses about it;
أَوَلَمْ يَكُن لَّهُمْ آيَةً أَن يَعْلَمَهُ عُلَمَاءُ بَنِي إِسْرَائِيلَ
Is it not a Sign to them that the Learned of the Children of Israel knew it (as true).
وَقَالَ لَهُمْ نَبِيُّهُمْ إِنَّ آيَةَ مُلْكِهِ أَن يَأْتِيَكُمُ التَّابُوتُ فِيهِ سَكِينَةٌ مِّن رَّبِّكُمْ وَبَقِيَّةٌ مِّمَّا تَرَكَ آلُ مُوسَىٰ وَآلُ هَارُونَ تَحْمِلُهُ الْمَلَائِكَةُ ۚ إِنَّ فِي ذَٰلِكَ لَآيَةً لَّكُمْ إِن كُنتُم مُّؤْمِنِينَ
And (further) their Prophet said to them: "A Sign of his authority is that there shall come to you the Ark of the covenant, with (an assurance) therein of security from your Lord, and the relics left by the family of Moses and the family of Aaron, carried by angels. In this is a symbol for you if ye indeed have faith.
خَلَقَ اللَّهُ السَّمَاوَاتِ وَالْأَرْضَ بِالْحَقِّ ۚ إِنَّ فِي ذَٰلِكَ لَآيَةً لِّلْمُؤْمِنِينَ
Allah created the heavens and the earth in true (proportions): verily in that is a Sign for those who believe.
يُنبِتُ لَكُم بِهِ الزَّرْعَ وَالزَّيْتُونَ وَالنَّخِيلَ وَالْأَعْنَابَ وَمِن كُلِّ الثَّمَرَاتِ ۗ إِنَّ فِي ذَٰلِكَ لَآيَةً لِّقَوْمٍ يَتَفَكَّرُونَ
With it He produces for you corn, olives, date-palms, grapes and every kind of fruit: verily in this is a sign for those who give thought.
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.
Meaning that is applied for the word '' verse'' in Quran is same miracle. Its purpose is that no one can bring like it. In other words, miracle does not go beyond creatures and if a person has power of miracle, it will be according to power and permission of creator. Naturally, creator has power for everything and creatures are weak for everything. Some persons think that miracle is a supernatural affair.
Whatever is related to supernatural events is miracle. Moreover, miracles are not affairs that nature denies them, but it is something that material system determines in each time. Science cannot deny occurrence of supernatural and hidden events. Wisdom of God is that there are natural creatures with specific relations.
Quran states
فَإِذَا بَلَغْنَ أَجَلَهُنَّ فَأَمْسِكُوهُنَّ بِمَعْرُوفٍ أَوْ فَارِقُوهُنَّ بِمَعْرُوفٍ وَأَشْهِدُوا ذَوَيْ عَدْلٍ مِّنكُمْ وَأَقِيمُوا الشَّهَادَةَ لِلَّهِ ۚ ذَٰلِكُمْ يُوعَظُ بِهِ مَن كَانَ يُؤْمِنُ بِاللَّهِ وَالْيَوْمِ الْآخِرِ ۚ وَمَن يَتَّقِ اللَّهَ يَجْعَل لَّهُ مَخْرَجًا
Thus when they fulfil their term appointed, either take them back on equitable terms or part with them on equitable terms; and take for witness two persons from among you, endued with justice, and establish the evidence (as) before Allah. Such is the admonition given to him who believes in Allah and the Last Day. And for those who fear Allah, He (ever) prepares a way out.
وَيَرْزُقْهُ مِنْ حَيْثُ لَا يَحْتَسِبُ ۚ وَمَن يَتَوَكَّلْ عَلَى اللَّهِ فَهُوَ حَسْبُهُ ۚ إِنَّ اللَّهَ بَالِغُ أَمْرِهِ ۚ قَدْ جَعَلَ اللَّهُ لِكُلِّ شَيْءٍ قَدْرًا
And He provides for him from (sources) he never could imagine. And if any one puts his trust in Allah, sufficient is (Allah) for him. For Allah will surely accomplish his purpose: verily, for all things has Allah appointed a due proportion.
The above verse reminds that each thing has magnitude that God has determined and it has relationships with other creatures. In fact, material creatures are dependent on other material creatures.
وَقَالَ الَّذِي اشْتَرَاهُ مِن مِّصْرَ لِامْرَأَتِهِ أَكْرِمِي مَثْوَاهُ عَسَىٰ أَن يَنفَعَنَا أَوْ نَتَّخِذَهُ وَلَدًا ۚ وَكَذَٰلِكَ مَكَّنَّا لِيُوسُفَ فِي الْأَرْضِ وَلِنُعَلِّمَهُ مِن تَأْوِيلِ الْأَحَادِيثِ ۚ وَاللَّهُ غَالِبٌ عَلَىٰ أَمْرِهِ وَلَٰكِنَّ أَكْثَرَ النَّاسِ لَا يَعْلَمُونَ
The man in Egypt who bought him, said to his wife: "Make his stay (among us) honourable: may be he will bring us much good, or we shall adopt him as a son." Thus did We establish Joseph in the land, that We might teach him the interpretation of stories (and events). And Allah hath full power and control over His affairs; but most among mankind know it not.
The above verse reminds that God has determined relationships among things and this does not deny relationship among things. But this matter proves that things are under power of God and he changes them however he or she likes. Quran states
كَتَبَ اللَّهُ لَأَغْلِبَنَّ أَنَا وَرُسُلِي ۚ إِنَّ اللَّهَ قَوِيٌّ عَزِيزٌ
Allah has decreed: "It is I and My messengers who must prevail": For Allah is One full of strength, able to enforce His Will''.
إِنَّا لَنَنصُرُ رُسُلَنَا وَالَّذِينَ آمَنُوا فِي الْحَيَاةِ الدُّنْيَا وَيَوْمَ يَقُومُ الْأَشْهَادُ
We will, without doubt, help our messengers and those who believe, (both) in this world´s life and on the Day when the Witnesses will stand forth.
Miracle is dependent on natural cause according to will and permission of God and challenge of miracle is related to correctness of prophesy and invitation toward God.
Ghazali says '' there are three kinds of miracle: sense miracle, rational miracle and fancy miracle''.
Quran states
تُسَبِّحُ لَهُ السَّمَاوَاتُ السَّبْعُ وَالْأَرْضُ وَمَن فِيهِنَّ ۚ وَإِن مِّن شَيْءٍ إِلَّا يُسَبِّحُ بِحَمْدِهِ وَلَٰكِن لَّا تَفْقَهُونَ تَسْبِيحَهُمْ ۗ إِنَّهُ كَانَ حَلِيمًا غَفُورًا
The seven heavens and the earth, and all beings therein, declare His glory: there is not a thing but celebrates His praise; And yet ye understand not how they declare His glory! Verily He is Oft-Forbear, Most Forgiving.
رَّسُولًا يَتْلُو عَلَيْكُمْ آيَاتِ اللَّهِ مُبَيِّنَاتٍ لِّيُخْرِجَ الَّذِينَ آمَنُوا وَعَمِلُوا الصَّالِحَاتِ مِنَ الظُّلُمَاتِ إِلَى النُّورِ ۚ وَمَن يُؤْمِن بِاللَّهِ وَيَعْمَلْ صَالِحًا يُدْخِلْهُ جَنَّاتٍ تَجْرِي مِن تَحْتِهَا الْأَنْهَارُ خَالِدِينَ فِيهَا أَبَدًا ۖ قَدْ أَحْسَنَ اللَّهُ لَهُ رِزْقًا
An Messenger, who rehearses to you the Signs of Allah containing clear explanations, that he may lead forth those who believe and do righteous deeds from the depths of Darkness into Light. And those who believe in Allah and work righteousness, He will admit to Gardens beneath which Rivers flow, to dwell therein for ever: Allah has indeed granted for them a most excellent Provision.
أَسْكِنُوهُنَّ مِنْ حَيْثُ سَكَنتُم مِّن وُجْدِكُمْ وَلَا تُضَارُّوهُنَّ لِتُضَيِّقُوا عَلَيْهِنَّ ۚ وَإِن كُنَّ أُولَاتِ حَمْلٍ فَأَنفِقُوا عَلَيْهِنَّ حَتَّىٰ يَضَعْنَ حَمْلَهُنَّ ۚ فَإِنْ أَرْضَعْنَ لَكُمْ فَآتُوهُنَّ أُجُورَهُنَّ ۖ وَأْتَمِرُوا بَيْنَكُم بِمَعْرُوفٍ ۖ وَإِن تَعَاسَرْتُمْ فَسَتُرْضِعُ لَهُ أُخْرَىٰ
Let the women live (in ´iddat) in the same style as ye live, according to your means: Annoy them not, so as to restrict them. And if they carry (life in their wombs), then spend (your substance) on them until they deliver their burden: and if they suckle your (offspring), give them their recompense: and take mutual counsel together, according to what is just and reasonable. And if ye find yourselves in difficulties, let another woman suckle (the child) on the (father´s) behalf.
يَا أَيُّهَا النَّبِيُّ إِذَا طَلَّقْتُمُ النِّسَاءَ فَطَلِّقُوهُنَّ لِعِدَّتِهِنَّ وَأَحْصُوا الْعِدَّةَ ۖ وَاتَّقُوا اللَّهَ رَبَّكُمْ ۖ لَا تُخْرِجُوهُنَّ مِن بُيُوتِهِنَّ وَلَا يَخْرُجْنَ إِلَّا أَن يَأْتِينَ بِفَاحِشَةٍ مُّبَيِّنَةٍ ۚ وَتِلْكَ حُدُودُ اللَّهِ ۚ وَمَن يَتَعَدَّ حُدُودَ اللَّهِ فَقَدْ ظَلَمَ نَفْسَهُ ۚ لَا تَدْرِي لَعَلَّ اللَّهَ يُحْدِثُ بَعْدَ ذَٰلِكَ أَمْرًا
O Prophet! When ye do divorce women, divorce them at their prescribed periods, and count (accurately), their prescribed periods: And fear Allah your Lord: and turn them not out of their houses, nor shall they (themselves) leave, except in case they are guilty of some open lewdness, those are limits set by Allah: and any who transgresses the limits of Allah, does verily wrong his (own) soul: thou knowest not if perchance Allah will bring about thereafter some new situation.
وَإِذْ قُلْتُمْ يَا مُوسَىٰ لَن نَّصْبِرَ عَلَىٰ طَعَامٍ وَاحِدٍ فَادْعُ لَنَا رَبَّكَ يُخْرِجْ لَنَا مِمَّا تُنبِتُ الْأَرْضُ مِن بَقْلِهَا وَقِثَّائِهَا وَفُومِهَا وَعَدَسِهَا وَبَصَلِهَا ۖ قَالَ أَتَسْتَبْدِلُونَ الَّذِي هُوَ أَدْنَىٰ بِالَّذِي هُوَ خَيْرٌ ۚ اهْبِطُوا مِصْرًا فَإِنَّ لَكُم مَّا سَأَلْتُمْ ۗ وَضُرِبَتْ عَلَيْهِمُ الذِّلَّةُ وَالْمَسْكَنَةُ وَبَاءُوا بِغَضَبٍ مِّنَ اللَّهِ ۗ ذَٰلِكَ بِأَنَّهُمْ كَانُوا يَكْفُرُونَ بِآيَاتِ اللَّهِ وَيَقْتُلُونَ النَّبِيِّينَ بِغَيْرِ الْحَقِّ ۗ ذَٰلِكَ بِمَا عَصَوا وَّكَانُوا يَعْتَدُونَ
And remember ye said: "O Moses! we cannot endure one kind of food (always); so beseech thy Lord for us to produce for us of what the earth groweth, -its pot-herbs, and cucumbers, Its garlic, lentils, and onions." He said: "Will ye exchange the better for the worse? Go ye down to any town, and ye shall find what ye want!" They were covered with humiliation and misery; they drew on themselves the wrath of Allah. This because they went on rejecting the Signs of Allah and slaying His Messengers without just cause. This because they rebelled and went on transgressing.
ثُمَّ أَنتُمْ هَٰؤُلَاءِ تَقْتُلُونَ أَنفُسَكُمْ وَتُخْرِجُونَ فَرِيقًا مِّنكُم مِّن دِيَارِهِمْ تَظَاهَرُونَ عَلَيْهِم بِالْإِثْمِ وَالْعُدْوَانِ وَإِن يَأْتُوكُمْ أُسَارَىٰ تُفَادُوهُمْ وَهُوَ مُحَرَّمٌ عَلَيْكُمْ إِخْرَاجُهُمْ ۚ أَفَتُؤْمِنُونَ بِبَعْضِ الْكِتَابِ وَتَكْفُرُونَ بِبَعْضٍ ۚ فَمَا جَزَاءُ مَن يَفْعَلُ ذَٰلِكَ مِنكُمْ إِلَّا خِزْيٌ فِي الْحَيَاةِ الدُّنْيَا ۖ وَيَوْمَ الْقِيَامَةِ يُرَدُّونَ إِلَىٰ أَشَدِّ الْعَذَابِ ۗ وَمَا اللَّهُ بِغَافِلٍ عَمَّا تَعْمَلُونَ
After this it is ye, the same people, who slay among yourselves, and banish a party of you from their homes; assist (Their enemies) against them, in guilt and rancour; and if they come to you as captives, ye ransom them, though it was not lawful for you to banish them. Then is it only a part of the Book that ye believe in, and do ye reject the rest? but what is the reward for those among you who behave like this but disgrace in this life?- and on the Day of Judgment they shall be consigned to the most grievous penalty. For Allah is not unmindful of what ye do.
وَاتَّبَعُوا مَا تَتْلُو الشَّيَاطِينُ عَلَىٰ مُلْكِ سُلَيْمَانَ ۖ وَمَا كَفَرَ سُلَيْمَانُ وَلَٰكِنَّ الشَّيَاطِينَ كَفَرُوا يُعَلِّمُونَ النَّاسَ السِّحْرَ وَمَا أُنزِلَ عَلَى الْمَلَكَيْنِ بِبَابِلَ هَارُوتَ وَمَارُوتَ ۚ وَمَا يُعَلِّمَانِ مِنْ أَحَدٍ حَتَّىٰ يَقُولَا إِنَّمَا نَحْنُ فِتْنَةٌ فَلَا تَكْفُرْ ۖ فَيَتَعَلَّمُونَ مِنْهُمَا مَا يُفَرِّقُونَ بِهِ بَيْنَ الْمَرْءِ وَزَوْجِهِ ۚ وَمَا هُم بِضَارِّينَ بِهِ مِنْ أَحَدٍ إِلَّا بِإِذْنِ اللَّهِ ۚ وَيَتَعَلَّمُونَ مَا يَضُرُّهُمْ وَلَا يَنفَعُهُمْ ۚ وَلَقَدْ عَلِمُوا لَمَنِ اشْتَرَاهُ مَا لَهُ فِي الْآخِرَةِ مِنْ خَلَاقٍ ۚ وَلَبِئْسَ مَا شَرَوْا بِهِ أَنفُسَهُمْ ۚ لَوْ كَانُوا يَعْلَمُونَ
They followed what the evil ones gave out (falsely) against the power of Solomon: the blasphemers Were, not Solomon, but the evil ones, teaching men Magic, and such things as came down at babylon to the angels Harut and Marut. But neither of these taught anyone (Such things) without saying: "We are only for trial; so do not blaspheme." They learned from them the means to sow discord between man and wife. But they could not thus harm anyone except by Allah´s permission. And they learned what harmed them, not what profited them. And they knew that the buyers of (magic) would have no share in the happiness of the Hereafter. And vile was the price for which they did sell their souls, if they but knew.
أَمْ حَسِبْتُمْ أَن تَدْخُلُوا الْجَنَّةَ وَلَمَّا يَأْتِكُم مَّثَلُ الَّذِينَ خَلَوْا مِن قَبْلِكُم ۖ مَّسَّتْهُمُ الْبَأْسَاءُ وَالضَّرَّاءُ وَزُلْزِلُوا حَتَّىٰ يَقُولَ الرَّسُولُ وَالَّذِينَ آمَنُوا مَعَهُ مَتَىٰ نَصْرُ اللَّهِ ۗ أَلَا إِنَّ نَصْرَ اللَّهِ قَرِيبٌ
Or do ye think that ye shall enter the Garden (of bliss) without such (trials) as came to those who passed away before you? they encountered suffering and adversity, and were so shaken in spirit that even the Messenger and those of faith who were with him cried: "When (will come) the help of Allah?" Ah! Verily, the help of Allah is (always) near.
