1. 4:11 يُوصِيكُمُ ٱللَّهُ فِىٓ أَوْلَٰدِكُمْ لِلذَّكَرِ مِثْلُ حَظِّ ٱلْأُنثَيَيْنِ فَإِن كُنَّ نِسَآءً فَوْقَ ٱثْنَتَيْنِ فَلَهُنَّ ثُلُثَا مَا تَرَكَ وَإِن كَانَتْ وَٰحِدَةً فَلَهَا ٱلنِّصْفُ وَلِأَبَوَيْهِ لِكُلِّ وَٰحِدٍ مِّنْهُمَا ٱلسُّدُسُ مِمَّا تَرَكَ إِن كَانَ لَهُۥ وَلَدٌ فَإِن لَّمْ يَكُن لَّهُۥ وَلَدٌ وَوَرِثَهُۥٓ أَبَوَاهُ فَلِأُمِّهِ ٱلثُّلُثُ فَإِن كَانَ لَهُۥٓ إِخْوَةٌ فَلِأُمِّهِ ٱلسُّدُسُ مِنۢ بَعْدِ وَصِيَّةٍ يُوصِى بِهَآ أَوْ دَيْنٍ ءَابَآؤُكُمْ وَأَبْنَآؤُكُمْ لَا تَدْرُونَ أَيُّهُمْ أَقْرَبُ لَكُمْ نَفْعًا فَرِيضَةً مِّنَ ٱللَّهِ إِنَّ ٱللَّهَ كَانَ عَلِيمًا حَكِيمًا

   Allah enjoins you concerning your children: The male shall have the equal of the portion of two females; then if they are more than two females, they shall have two-thirds of what the deceased has left, and if there is one, she shall have the half; and as for his parents, each of them shall have the sixth of what he has left if he has a child, but if he has no child and (only) his two parents inherit him, then his mother shall have the third; but if he has brothers, then his mother shall have the sixth after (the payment of) a bequest he may have bequeathed or a debt; your parents and your children, you know not which of them is the nearer to you in usefulness; this is an ordinance from Allah: Surely Allah is Knowing, Wise.
   

2. 10:16 قُل لَّوْ شَآءَ ٱللَّهُ مَا تَلَوْتُهُۥ عَلَيْكُمْ وَلَآ أَدْرَىٰكُم بِهِۦ فَقَدْ لَبِثْتُ فِيكُمْ عُمُرًا مِّن قَبْلِهِۦٓ أَفَلَا تَعْقِلُونَ

   Say: If Allah had desired (otherwise) I would not have recited it to you, nor would He have taught it to you; indeed I have lived a lifetime among you before it; do you not then understand?
   

3. 21:109 فَإِن تَوَلَّوْا۟ فَقُلْ ءَاذَنتُكُمْ عَلَىٰ سَوَآءٍ وَإِنْ أَدْرِىٓ أَقَرِيبٌ أَم بَعِيدٌ مَّا تُوعَدُونَ

   But if they turn back, say: I have given you warning in fairness and I do not know whether what you are threatened with is near or far;
   

4. 21:111 وَإِنْ أَدْرِى لَعَلَّهُۥ فِتْنَةٌ لَّكُمْ وَمَتَٰعٌ إِلَىٰ حِينٍ

   And I do not know if this may be a trial for you and a provision till a time.
   

5. 31:34 إِنَّ ٱللَّهَ عِندَهُۥ عِلْمُ ٱلسَّاعَةِ وَيُنَزِّلُ ٱلْغَيْثَ وَيَعْلَمُ مَا فِى ٱلْأَرْحَامِ وَمَا تَدْرِى نَفْسٌ مَّاذَا تَكْسِبُ غَدًا وَمَا تَدْرِى نَفْسٌۢ بِأَىِّ أَرْضٍ تَمُوتُ إِنَّ ٱللَّهَ عَلِيمٌ خَبِيرٌۢ

   Surely Allah is He with Whom is the knowledge of the hour, and He sends down the rain and He knows what is in the wombs; and no one knows what he shall earn on the morrow; and no one knows in what land he shall die; surely Allah is Knowing, Aware.
   

6. 33:63 يَسْـَٔلُكَ ٱلنَّاسُ عَنِ ٱلسَّاعَةِ قُلْ إِنَّمَا عِلْمُهَا عِندَ ٱللَّهِ وَمَا يُدْرِيكَ لَعَلَّ ٱلسَّاعَةَ تَكُونُ قَرِيبًا

   Men ask you about the hour; say: The knowledge of it is only with Allah, and what will make you comprehend that the : hour may be nigh.
   

7. 42:17 ٱللَّهُ ٱلَّذِىٓ أَنزَلَ ٱلْكِتَٰبَ بِٱلْحَقِّ وَٱلْمِيزَانَ وَمَا يُدْرِيكَ لَعَلَّ ٱلسَّاعَةَ قَرِيبٌ

   Allah it is Who revealed the Book with truth, and the balance, and what shall make you know that haply the hour be nigh?
   

8. 42:52 وَكَذَٰلِكَ أَوْحَيْنَآ إِلَيْكَ رُوحًا مِّنْ أَمْرِنَا مَا كُنتَ تَدْرِى مَا ٱلْكِتَٰبُ وَلَا ٱلْإِيمَٰنُ وَلَٰكِن جَعَلْنَٰهُ نُورًا نَّهْدِى بِهِۦ مَن نَّشَآءُ مِنْ عِبَادِنَا وَإِنَّكَ لَتَهْدِىٓ إِلَىٰ صِرَٰطٍ مُّسْتَقِيمٍ

   And thus did We reveal to you an inspired book by Our command. You did not know what the Book was, nor (what) the faith (was), but We made it a light, guiding thereby whom We please of Our servants; and most surely you show the way to the right path:
   

9. 45:32 وَإِذَا قِيلَ إِنَّ وَعْدَ ٱللَّهِ حَقٌّ وَٱلسَّاعَةُ لَا رَيْبَ فِيهَا قُلْتُم مَّا نَدْرِى مَا ٱلسَّاعَةُ إِن نَّظُنُّ إِلَّا ظَنًّا وَمَا نَحْنُ بِمُسْتَيْقِنِينَ

   And when it was said, Surely the promise of Allah is true and as for the hour, there is no doubt about it, you said: We do not know what the hour is; we do not think (that it will come to pass) save a passing thought, and we are not at all sure.
   

10. 46:9 قُلْ مَا كُنتُ بِدْعًا مِّنَ ٱلرُّسُلِ وَمَآ أَدْرِى مَا يُفْعَلُ بِى وَلَا بِكُمْ إِنْ أَتَّبِعُ إِلَّا مَا يُوحَىٰٓ إِلَىَّ وَمَآ أَنَا۠ إِلَّا نَذِيرٌ مُّبِينٌ

    Say: I am not the first of the messengers, and I do not know what will be done with me or with you: I do not follow anything but that which is revealed to me, and I am nothing but a plain warner.
    

11. 65:1 يَٰٓأَيُّهَا ٱلنَّبِىُّ إِذَا طَلَّقْتُمُ ٱلنِّسَآءَ فَطَلِّقُوهُنَّ لِعِدَّتِهِنَّ وَأَحْصُوا۟ ٱلْعِدَّةَ وَٱتَّقُوا۟ ٱللَّهَ رَبَّكُمْ لَا تُخْرِجُوهُنَّ مِنۢ بُيُوتِهِنَّ وَلَا يَخْرُجْنَ إِلَّآ أَن يَأْتِينَ بِفَٰحِشَةٍ مُّبَيِّنَةٍ وَتِلْكَ حُدُودُ ٱللَّهِ وَمَن يَتَعَدَّ حُدُودَ ٱللَّهِ فَقَدْ ظَلَمَ نَفْسَهُۥ لَا تَدْرِى لَعَلَّ ٱللَّهَ يُحْدِثُ بَعْدَ ذَٰلِكَ أَمْرًا

    O Prophet! when you divorce women, divorce them for~ their prescribed time, and calculate the number of the days prescribed, and be careful of (your duty to) Allah, your Lord. Do not drive them out of their houses, nor should they themselves go forth, unless they commit an open indecency; and these are the limits of Allah, and whoever goes beyond the limits of Allah, he indeed does injustice to his own soul. You do not know that Allah may after that bring about reunion.
    

12. 69:3 وَمَآ أَدْرَىٰكَ مَا ٱلْحَآقَّةُ

    And what would make you realize what the sure calamity is!
    

13. 69:26 وَلَمْ أَدْرِ مَا حِسَابِيَهْ

    And I had not known what my account was:
    

14. 72:10 وَأَنَّا لَا نَدْرِىٓ أَشَرٌّ أُرِيدَ بِمَن فِى ٱلْأَرْضِ أَمْ أَرَادَ بِهِمْ رَبُّهُمْ رَشَدًا

    And that we know not whether evil is meant for those who are on earth or whether their Lord means to bring them good:
    

15. 72:25 قُلْ إِنْ أَدْرِىٓ أَقَرِيبٌ مَّا تُوعَدُونَ أَمْ يَجْعَلُ لَهُۥ رَبِّىٓ أَمَدًا

    Say: I do not know whether that with which you are threatened be nigh or whether my Lord will appoint for it a term:
