The Quran

Preface

۞ وَلَكُم نِصفُ ما تَرَكَ أَزواجُكُم إِن لَم يَكُن لَهُنَّ وَلَدٌ ۚ فَإِن كانَ لَهُنَّ وَلَدٌ فَلَكُمُ الرُّبُعُ مِمّا تَرَكنَ ۚ مِن بَعدِ وَصِيَّةٍ يوصينَ بِها أَو دَينٍ ۚ وَلَهُنَّ الرُّبُعُ مِمّا تَرَكتُم إِن لَم يَكُن لَكُم وَلَدٌ ۚ فَإِن كانَ لَكُم وَلَدٌ فَلَهُنَّ الثُّمُنُ مِمّا تَرَكتُم ۚ مِن بَعدِ وَصِيَّةٍ توصونَ بِها أَو دَينٍ ۗ وَإِن كانَ رَجُلٌ يورَثُ كَلالَةً أَوِ امرَأَةٌ وَلَهُ أَخٌ أَو أُختٌ فَلِكُلِّ واحِدٍ مِنهُمَا السُّدُسُ ۚ فَإِن كانوا أَكثَرَ مِن ذٰلِكَ فَهُم شُرَكاءُ فِي الثُّلُثِ ۚ مِن بَعدِ وَصِيَّةٍ يوصىٰ بِها أَو دَينٍ غَيرَ مُضارٍّ ۚ وَصِيَّةً مِنَ اللَّهِ ۗ وَاللَّهُ عَليمٌ حَليمٌ

Ali Quli Qarai

For you shall be a half of what your wives leave, if they have no children; but if they have children, then for you shall be a fourth of what they leave, after [paying off] any bequest they may have made or any debt [they may have incurred]. And for them [it shall be] a fourth of what you leave, if you have no children; but if you have children, then for them shall be an eighth of what you leave, after [paying off] any bequest you may have made or any debt [you may have incurred]. If a man or woman is inherited by siblings¹ and has a brother or a sister, then each of them shall receive a sixth; but if they are more than that, then they shall share in one third, after [paying off] any bequest he may have made or any debt [he may have incurred] without prejudice.² [This is] an enjoinment from Allah, and Allah is all-knowing, all-forbearing.

Kalālah means the siblings of a deceased person without a first-degree heir. See verse 4:176 below.
That is, the will should not encroach on the rights of the heirs, for instance by acknowledging a nonexistent debt.
