Muwatta Imam Malik Book of Fara'id, Hadith 9
Yahya related to me from Malik that Muhammad ibn Abi Bakr ibn Hazm heard his father say many times, ''Umar ibn al-Khattab used to say, 'It is a wonder that the paternal aunt is inherited from and does not inherit.' "
وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ مُحَمَّدِ بْنِ أَبِي بَكْرِ بْنِ حَزْمٍ، أَنَّهُ سَمِعَ أَبَاهُ، كَثِيرًا يَقُولُ كَانَ عُمَرُ بْنُ الْخَطَّابِ يَقُولُ عَجَبًا لِلْعَمَّةِ تُورَثُ وَلاَ تَرِثُ .
