Luqman - 31:27 If all the trees of the earth were pens, and seven seas were added to the seas, Allah´s words would not be exhausted. Allah is Exalted, Wise.
The words of your Lord are complete:
The Heights/7:52 We have brought them a Book which We have detailed with knowledge, a guidance and mercy for a people who believe.
وَلَقَدْ جِئْنَاهُمْ بِكِتَابٍ فَصَّلْنَاهُ عَلٰى عِلْمٍ هُدًى وَرَحْمَةً لِقَوْمٍ يُؤْمِنُونَ

Luqman/31:27 If all the trees of the earth were pens, and seven seas were added to the seas, Allah´s words would not be exhausted. Allah is Exalted, Wise.
وَلَوْ اَنَّ مَا فِي الْاَرْضِ مِنْ شَجَرَةٍ اَقْلَامٌ وَالْبَحْرُ يَمُدُّهُ مِنْ بَعْدِه۪ سَبْعَةُ اَبْحُرٍ مَا نَفِدَتْ كَلِمَاتُ اللّٰهِۜ اِنَّ اللّٰهَ عَز۪يزٌ حَك۪يمٌ

The Table Spread/5:101 Believers, do not ask questions about what you do not like when it is explained to you. If you ask in the light of the Qur´an, they will become clear to you. Allah has not specifically mentioned them. Allah is Forgiving, Mild.
يَٓا اَيُّهَا الَّذ۪ينَ اٰمَنُوا لَا تَسْـَٔلُوا عَنْ اَشْيَٓاءَ اِنْ تُبْدَ لَكُمْ تَسُؤْكُمْۚ وَاِنْ تَسْـَٔلُوا عَنْهَا ح۪ينَ يُنَزَّلُ الْقُرْاٰنُ تُبْدَ لَكُمْۜ عَفَا اللّٰهُ عَنْهَاۜ وَاللّٰهُ غَفُورٌ حَل۪يمٌ

The Cattle/6:114 Shall I seek a lawgiver besides Allah, Who has sent down to you the Book in detail? Those to whom We have given the Book know that it has been sent down from your Lord. So do not be of those who doubt.
اَفَغَيْرَ اللّٰهِ اَبْتَغ۪ي حَكَماً وَهُوَ الَّـذ۪ٓي اَنْزَلَ اِلَيْكُمُ الْكِتَابَ مُفَصَّلاًۜ وَالَّذ۪ينَ اٰتَيْنَاهُمُ الْكِتَابَ يَعْلَمُونَ اَنَّهُ مُنَزَّلٌ مِنْ رَبِّكَ بِالْحَقِّ فَلَا تَكُونَنَّ مِنَ الْمُمْتَر۪ينَ
The Cattle/6:115 The words of your Lord are complete in truth and justice. There is none who can change His words. He is the Hearing, the Knowing.
وَتَمَّتْ كَلِمَتُ رَبِّكَ صِدْقاً وَعَدْلاًۜ لَا مُبَدِّلَ لِكَلِمَاتِه۪ۚ وَهُوَ السَّم۪يعُ الْعَل۪يمُ

Prophet Jonah/10:37 This Qur´an is not a book edited by anyone other than Allah. It is but a detailed explanation of the Book (of laws), confirming what has gone before it. Make no doubt about it; it is from the Lord of the universes.
وَمَا كَانَ هٰذَا الْقُرْاٰنُ اَنْ يُفْتَرٰى مِنْ دُونِ اللّٰهِ وَلٰكِنْ تَصْد۪يقَ الَّذ۪ي بَيْنَ يَدَيْهِ وَتَفْص۪يلَ الْكِتَابِ لَا رَيْبَ ف۪يهِ مِنْ رَبِّ الْعَالَم۪ينَ۠

Prophet Hud/11:1 A.L.R. (This is) a Book whose verses have been made firm by One Wise and All-Knowing, and then explained and elaborated.
الٓـرٰ۠ كِتَابٌ اُحْكِمَتْ اٰيَاتُهُ ثُمَّ فُصِّلَتْ مِنْ لَدُنْ حَك۪يمٍ خَب۪يرٍۙ

Prophet Joseph/12:111 In their history is a lesson for those who are conscious. This is not a fabricated hadith, but a confirmation of what has gone before it, a detailed explanation of everything, and a guidance and Mercy for those who believe.
لَقَدْ كَانَ ف۪ي قَصَصِهِمْ عِبْرَةٌ لِاُو۬لِي الْاَلْبَابِۜ مَا كَانَ حَد۪يثاً يُفْتَرٰى وَلٰكِنْ تَصْد۪يقَ الَّذ۪ي بَيْنَ يَدَيْهِ وَتَفْص۪يلَ كُلِّ شَيْءٍ وَهُدًى وَرَحْمَةً لِقَوْمٍ يُؤْمِنُونَ

The Cave/18:27 Read what has been revealed to you from the Book of your Lord. Nothing can change or remove His words, and you will find no refuge besides Him.
وَاتْلُ مَٓا اُو۫حِيَ اِلَيْكَ مِنْ كِتَابِ رَبِّكَۚ لَا مُبَدِّلَ لِكَلِمَاتِه۪ وَلَنْ تَجِدَ مِنْ دُونِه۪ مُلْتَحَداً
