Sura al-Nisāʾ 4:11

يُوصِيكُمُ ٱللَّـهُ 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 ٱللَّـهِ إِنَّ ٱللَّـهَ كَانَ عَلِيمًا حَكِيمًا

Allah (thus) directs you as regards your Children's (Inheritance): to the male, a portion equal to that of two females: if only daughters, two or more, their share is two-thirds of the inheritance; if only one, her share is a half. For parents, a sixth share of the inheritance to each, if the deceased left children; if no children, and the parents are the (only) heirs, the mother has a third; if the deceased Left brothers (or sisters) the mother has a sixth. (The distribution in all cases ('s) after the payment of legacies and debts. Ye know not whether your parents or your children are nearest to you in benefit. These are settled portions ordained by Allah; and Allah is All-knowing, Al-wise.

Sura al-Jāthiyah 45:32

وَإِذَا قِيلَ إِنَّ وَعْدَ ٱللَّـهِ حَقٌّ وَٱلسَّاعَةُ لَا رَيْبَ فِيهَا قُلْتُم مَّا نَدْرِى مَا ٱلسَّاعَةُ إِن نَّظُنُّ إِلَّا ظَنًّا وَمَا نَحْنُ بِمُسْتَيْقِنِينَ

wa-idhā qīla inna waʿda allāhi ḥaqqun wa-l-sāʿatu lā rayba fīhā qultum mā nadrī mā l-sāʿatu in naẓunnu illā ẓannan wa-mā naḥnu bimustayqinīna

"And when it was said that the promise of Allah was true, and that the Hour- there was no doubt about its (coming), ye used to say, 'We know not what is the hour: we only think it is an idea, and we have no firm assurance.'"

Sura al-Jinn 72:10

وَأَنَّا لَا نَدْرِىٓ أَشَرٌّ أُرِيدَ بِمَن فِى ٱلْأَرْضِ أَمْ أَرَادَ بِهِمْ رَبُّهُمْ رَشَدًا

wa-annā lā nadrī asharrun urīda biman fī l-arḍi am arāda bihim rabbuhum rashadan

'And we understand not whether ill is intended to those on earth, or whether their Lord (really) intends to guide them to right conduct.
