4:11
يُوصِيكُمُ اللَّهُ فِي أَوْلاَدِكُمْ لِلذَّكَرِ مِثْلُ حَظِّ الأُنثَيَيْنِ فَإِنْ كُنَّ نِسَاء ً فَوْقَ اثْنَتَيْنِ فَلَهُنَّ ثُلُثَا مَا تَرَكَ وَإِنْ كَانَتْ وَاحِدَة ً فَلَهَا النِّصْفُ وَلِأَبَوَيْهِ لِكُلِّ وَاحِد ٍ مِنْهُمَا السُّدُسُ مِمَّا تَرَكَ إِنْ كَانَ لَه ُُ وَلَد ٌ فَإِنْ لَمْ يَكُنْ لَه ُُ وَلَد ٌ وَوَرِثَهُ~ُ أَبَوَاه ُُ فَلِأَمِّهِ الثُّلُثُ فَإِنْ كَانَ لَهُ~ُ إِخْوَة ٌ فَلِأَمِّهِ السُّدُسُ مِنْ بَعْدِ وَصِيَّة ٍ يُوصِي بِهَا أَوْ دَيْن ٍ آبَاؤُكُمْ وَأَبْنَاؤُكُمْ لاَ تَدْرُونَ أَيُّهُمْ أَقْرَبُ لَكُمْ نَفْعا ً فَرِيضَة ً مِنَ اللَّهِ إِنَّ اللَّهَ كَانَ عَلِيماً حَكِيما ً

God directs you regarding the inheritance of your children: "To the male shall be as that given to two females. If they are women, more than two, then they will have two thirds of what is inherited. And if she is only one, then she will have one half. And to his parents, each one of them shall have one sixth of what is inherited, if he has a child. If he has no child and his parents are the heirs, then to his mother is one third; if he has siblings then to his mother is one sixth. All after a will is carried through or a debt. Your parents and your children, you do not know which are closer to you in benefit, a directive from God, for God is Knowledgeable, Wise."

يَسْتَفْتُونَكَ قُلِ اللَّهُ يُفْتِيكُمْ فِي الْكَلاَلَةِ إِنِ امْرُؤٌ هَلَكَ لَيْسَ لَه ُُ وَلَد ٌ وَلَهُ~ُ أُخْت ٌ فَلَهَا نِصْفُ مَا تَرَكَ وَهُوَ يَرِثُهَا إِنْ لَمْ يَكُنْ لَهَا وَلَد ٌ فَإِنْ كَانَتَا اثْنَتَيْنِ فَلَهُمَا الثُّلُثَانِ مِمَّا تَرَكَ وَإِنْ كَانُوا إِخْوَة ً رِجَالا ً وَنِسَاء ً فَلِلذَّكَرِ مِثْلُ حَظِّ الأُنثَيَيْنِ يُبَيِّنُ اللَّهُ لَكُمْ أَنْ تَضِلُّوا وَاللَّهُ بِكُلِّ شَيْءٍ عَلِيم ٌ

They seek a ruling from you, say: "God gives you the ruling for those who have no descendants. If a person passes away and has no children but has a sister, then she shall receive half of what he leaves behind. And he will inherit from her if she has no child. However, if he has two sisters, then they will receive two thirds of what he left behind; and if he has siblings, men and women, then the male shall receive twice what the female receives." God makes clear to you that you do not stray; God is aware of all things.

إِنَّ رَبَّكَ يَعْلَمُ أَنَّكَ تَقُومُ أَدْنَى مِنْ ثُلُثَيِ اللَّيْلِ وَنِصْفَه ُُ وَثُلُثَه ُُ وَطَائِفَة ٌ مِنَ الَّذِينَ مَعَكَ وَاللَّهُ يُقَدِّرُ اللَّيْلَ وَالنَّهَارَ عَلِمَ أَنْ لَنْ تُحْصُوه ُُ فَتَابَ عَلَيْكُمْ فَاقْرَءُوا مَا تَيَسَّرَ مِنَ الْقُرْآنِ عَلِمَ أَنْ سَيَكُونُ مِنْكُمْ مَرْضَى وَآخَرُونَ يَضْرِبُونَ فِي الأَرْضِ يَبْتَغُونَ مِنْ فَضْلِ اللَّهِ وَآخَرُونَ يُقَاتِلُونَ فِي سَبِيلِ اللَّهِ فَاقْرَءُوا مَا تَيَسَّرَ مِنْهُ وَأَقِيمُوا الصَّلاَةَ وَآتُوا الزَّكَاةَ وَأَقْرِضُوا اللَّهَ قَرْضاً حَسَنا ً وَمَا تُقَدِّمُوا لِأنْفُسِكُمْ مِنْ خَيْر ٍ تَجِدُوه ُُ عِنْدَ اللَّهِ هُوَ خَيْرا ً وَأَعْظَمَ أَجْرا ً وَاسْتَغْفِرُوا اللَّهَ إِنَّ اللَّهَ غَفُور ٌ رَحِيم ٌ

Your Lord knows that you rise a little less than two thirds of the night, and half of it, and one third of it; and a group of those who are with you. And God measures the night and the day. He knows that you will not be able to keep-up, so He pardons you. So read what is made easy of the Quran. He knows that there will be sick among you, and others that go forth in the land seeking from the bounty of God, and others who are fighting in the cause of God, so read what you can of it. And hold the contact prayer and contribute towards purification and lend God a loan of righteousness. And whatever you put forth yourselves, you will find it with God, for it is better and a greater reward. And seek the forgiveness of God, for God is Forgiving, Merciful.
