What Quran talks about itself
Sura al qamar verse 17 verse 22 verse 32 and verse 40
وَلَقَدْ يَسَّرْنَا الْقُرْآنَ لِلذِّكْرِ فَهَلْ مِن مُّدَّكِرٍ
And certainly We have made the Quran easy for remembrance, but is there anyone who will mind?
Sura qaf verse 46
نَّحْنُ أَعْلَمُ بِمَا يَقُولُونَ وَمَا أَنتَ عَلَيْهِم بِجَبَّارٍ فَذَكِّرْ بِالْقُرْآنِ مَن يَخَافُ وَعِيدِ
We know best what they say, and you are not one to compel them; therefore remind him by means of the Quran who fears My threat.
Sura Mohammad verse 24
أَفَلَا يَتَدَبَّرُونَ الْقُرْآنَ أَمْ عَلَىٰ قُلُوبٍ أَقْفَالُهَا
Do they not then think deeply in the Quran, or are their hearts locked up (from understanding it)?
Baqra verse 2
ذَٰلِكَ الْكِتَابُ لَا رَيْبَ فِيهِ هُدًى لِّلْمُتَّقِينَ
This is the Book (the Quran), whereof there is no doubt, a guidance to those who are Al-Muttaqun [the pious and righteous persons who fear Allah much (abstain from all kinds of sins and evil deeds which He has forbidden) and love Allah much (perform all kinds of good deeds which He has ordained)].
Nisa v 82
أَفَلَا يَتَدَبَّرُونَ الْقُرْآنَ وَلَوْ كَانَ مِنْ عِندِ غَيْرِ اللَّهِ لَوَجَدُوا فِيهِ اخْتِلَافًا كَثِيرًا
Do they not then consider the Quran carefully? Had it been from other than Allah, they would surely have found therein much contradictions.
يَا أَيُّهَا النَّاسُ قَدْ جَاءَكُم بُرْهَانٌ مِّن رَّبِّكُمْ وَأَنزَلْنَا إِلَيْكُمْ نُورًا مُّبِينًا
O mankind! Verily, there has come to you a convincing proof (Prophet Muhammad SAW) from your Lord, and We sent down to you a manifest light (this Quran).
Anaam v 82
وَهَٰذَا كِتَابٌ أَنزَلْنَاهُ مُبَارَكٌ مُّصَدِّقُ الَّذِي بَيْنَ يَدَيْهِ وَلِتُنذِرَ أُمَّ الْقُرَىٰ وَمَنْ حَوْلَهَا وَالَّذِينَ يُؤْمِنُونَ بِالْآخِرَةِ يُؤْمِنُونَ بِهِ وَهُمْ عَلَىٰ صَلَاتِهِمْ يُحَافِظُونَ
And this (the Quran) is a blessed Book which We have sent down, confirming (the revelations) which came before it, so that you may warn the Mother of Towns (i.e. Makkah) and all those around it. Those who believe in the Hereafter believe in (the Quran), and they are constant in guarding their Salat (prayers).
وَهَٰذَا كِتَابٌ أَنزَلْنَاهُ مُبَارَكٌ فَاتَّبِعُوهُ وَاتَّقُوا لَعَلَّكُمْ تُرْحَمُونَ
And this is a blessed Book (the Quran) which We have sent down, so follow it and fear Allah (i.e. do not disobey His Orders), that you may receive mercy (i.e. saved from the torment of Hell).
وَلَقَدْ جِئْنَاهُم بِكِتَابٍ فَصَّلْنَاهُ عَلَىٰ عِلْمٍ هُدًى وَرَحْمَةً لِّقَوْمٍ يُؤْمِنُونَ
Certainly, We have brought to them a Book (the Quran) which We have explained in detail with knowledge, – a guidance and a mercy to a people who believe.
وَإِذَا قُرِئَ الْقُرْآنُ فَاسْتَمِعُوا لَهُ وَأَنصِتُوا لَعَلَّكُمْ تُرْحَمُونَ
So, when the Quran is recited, listen to it, and be silent that you may receive mercy. [i.e. during the compulsory congregational prayers when the Imam (of a mosque) is leading the prayer (except Surat Al-Fatiha), and also when he is delivering the Friday-prayer Khutbah]. [Tafsir At-Tabari, Vol. 9, Pages 162-4]
Yunus v 37
وَمَا كَانَ هَٰذَا الْقُرْآنُ أَن يُفْتَرَىٰ مِن دُونِ اللَّهِ وَلَٰكِن تَصْدِيقَ الَّذِي بَيْنَ يَدَيْهِ وَتَفْصِيلَ الْكِتَابِ لَا رَيْبَ فِيهِ مِن رَّبِّ الْعَالَمِينَ
And this Quran is not such as could ever be produced by other than Allah (Lord of the heavens and the earth), but it is a confirmation of (the revelation) which was before it [i.e. the Taurat (Torah), and the Injeel (Gospel), etc.], and a full explanation of the Book (i.e. laws and orders, etc, decreed for mankind) – wherein there is no doubt from the the Lord of the ‘Alamin (mankind, jinns, and all that exists).
Raad v 1
المر تِلْكَ آيَاتُ الْكِتَابِ وَالَّذِي أُنزِلَ إِلَيْكَ مِن رَّبِّكَ الْحَقُّ وَلَٰكِنَّ أَكْثَرَ النَّاسِ لَا يُؤْمِنُونَ
Alif-Lam-Mim-Ra [These letters are one of the miracles of the Quran and none but Allah (Alone) knows their meanings]. These are the Verses of the Book (the Quran), and that which has been revealed unto you (Muhammad SAW) from your Lord is the truth, but most men believe not.
وَلَوْ أَنَّ قُرْآنًا سُيِّرَتْ بِهِ الْجِبَالُ أَوْ قُطِّعَتْ بِهِ الْأَرْضُ أَوْ كُلِّمَ بِهِ الْمَوْتَىٰ بَل لِّلَّهِ الْأَمْرُ جَمِيعًا أَفَلَمْ يَيْأَسِ الَّذِينَ آمَنُوا أَن لَّوْ يَشَاءُ اللَّهُ لَهَدَى النَّاسَ جَمِيعًا وَلَا يَزَالُ الَّذِينَ كَفَرُوا تُصِيبُهُم بِمَا صَنَعُوا قَارِعَةٌ أَوْ تَحُلُّ قَرِيبًا مِّن دَارِهِمْ حَتَّىٰ يَأْتِيَ وَعْدُ اللَّهِ إِنَّ اللَّهَ لَا يُخْلِفُ الْمِيعَادَ
And if there had been a Quran with which mountains could be moved (from their places), or the earth could be cloven asunder, or the dead could be made to speak (it would not have been other than this Quran). But the decision of all things is certainly with Allah. Have not then those who believe yet known that had Allah willed, He could have guided all mankind? And a disaster will not cease to strike those who disbelieve because of their (evil) deeds or it (i.e. the disaster) settle close to their homes, until the Promise of Allah comes to pass. Certainly, Allah does not fail in His Promise.
Ibrahim v 1
الر كِتَابٌ أَنزَلْنَاهُ إِلَيْكَ لِتُخْرِجَ النَّاسَ مِنَ الظُّلُمَاتِ إِلَى النُّورِ بِإِذْنِ رَبِّهِمْ إِلَىٰ صِرَاطِ الْعَزِيزِ الْحَمِيدِ
Alif-Lam-Ra. [These letters are one of the miracles of the Quran, and none but Allah (Alone) knows their meanings]. (This is) a Book which We have revealed unto you (O Muhammad SAW) in order that you might lead mankind out of darkness (of disbelief and polytheism) into light (of belief in the Oneness of Allah and Islamic Monotheism) by their Lord’s Leave to the Path of the All-Mighty, the Owner of all Praise.
هَٰذَا بَلَاغٌ لِّلنَّاسِ وَلِيُنذَرُوا بِهِ وَلِيَعْلَمُوا أَنَّمَا هُوَ إِلَٰهٌ وَاحِدٌ وَلِيَذَّكَّرَ أُولُو الْأَلْبَابِ
This (Quran) is a Message for mankind (and a clear proof against them), in order that they may be warned thereby, and that they may know that He is the only One Ilah (God – Allah) – (none has the right to be worshipped but Allah), and that men of understanding may take heed.
Isra v 9
إِنَّ هَٰذَا الْقُرْآنَ يَهْدِي لِلَّتِي هِيَ أَقْوَمُ وَيُبَشِّرُ الْمُؤْمِنِينَ الَّذِينَ يَعْمَلُونَ الصَّالِحَاتِ أَنَّ لَهُمْ أَجْرًا كَبِيرًا
Verily, this Quran guides to that which is most just and right and gives glad tidings to the believers (in the Oneness of Allah and His Messenger, Muhammad SAW, etc.). who work deeds of righteousness, that they shall have a great reward (Paradise).
وَلَقَدْ صَرَّفْنَا فِي هَٰذَا الْقُرْآنِ لِيَذَّكَّرُوا وَمَا يَزِيدُهُمْ إِلَّا نُفُورًا
And surely, We have explained [Our Promises, Warnings and (set forth many) examples] in this Quran that they (the disbelievers) may take heed, but it increases them in naught save aversion.
Kahf v 27
وَاتْلُ مَا أُوحِيَ إِلَيْكَ مِن كِتَابِ رَبِّكَ لَا مُبَدِّلَ لِكَلِمَاتِهِ وَلَن تَجِدَ مِن دُونِهِ مُلْتَحَدًا
And recite what has been revealed to you (O Muhammad SAW) of the Book (the Quran) of your Lord (i.e. recite it, understand and follow its teachings and act on its orders and preach it to men). None can change His Words, and none will you find as a refuge other than Him.
وَلَقَدْ صَرَّفْنَا فِي هَٰذَا الْقُرْآنِ لِلنَّاسِ مِن كُلِّ مَثَلٍ وَكَانَ الْإِنسَانُ أَكْثَرَ شَيْءٍ جَدَلًا
And indeed We have put forth every kind of example in this Quran, for mankind. But, man is ever more quarrelsome than anything.
