Prophetic Commentary on the Qur'an (Tafseer of the Prophet (pbuh))
65/4.28. Chapter:
"They ask you for a legal verdict. Say: 'Allah directs (thus) about Al-Kalal,a (those who leave neither descendants nor ascendants as heirs). If it is a man that dies, leaving a sister, but no child, she shall have half the inheritance. If (such a deceased was) a woman who left no child, her brother takes her inheritance..." (V.4:176)
وَالْكَلاَلَةُ مَنْ لَمْ يَرِثْهُ أَبٌ أَوِ ابْنٌ وَهْوَ مَصْدَرٌ مِنْ تَكَلَّلَهُ النَّسَبُ.
Sahih Bukhari
حَدَّثَنَا سُلَيْمَانُ بْنُ حَرْبٍ، حَدَّثَنَا شُعْبَةُ، عَنْ أَبِي إِسْحَاقَ، سَمِعْتُ الْبَرَاءَ ـ رضى الله عنه ـ قَالَ آخِرُ سُورَةٍ نَزَلَتْ بَرَاءَةَ، وَآخِرُ آيَةٍ نَزَلَتْ {يَسْتَفْتُونَكَ }
Narrated Al-Bara: The last Sura that was revealed was Bara'a, and the last Verse that was revealed was: "They ask you for a legal verdict, Say: Allah's directs (thus) about those who leave no descendants or ascendants as heirs." (4.176)
