Mishkat al-Masabih 3059
Huzail b. Shurahbil said:
Abu Musa was asked about a case where there were a daughter, a son’s daughter and a sister and replied, “The daughter gets half and the sister gets half. Go to Ibn Mas'ud and you will find that he agrees with me.” When Ibn Mas'ud was asked and told what Abu Musa had said he replied, “I would then be in error and not be one of those who are rightly guided. I decide concerning the matter as the Prophet did: The daughter gets half and the son’s daughter a sixth, making two-thirds, and what remains goes to the sister.” We then went to Abu Musa and when we told him what Ibn Mas'ud had said he replied, “Do not question me as long as this learned man is among you.” 

Bukhari transmitted it. (Here again we find a tradition by Bukhari in Section 2.)
وَعَنْ هُزَيْلِ بْنِ شُرَحْبِيلَ قَالَ: سُئِلَ أَبُو مُوسَى عَنِ ابْنَةٍ وَبِنْتِ ابْنٍ وَأُخْتٍ فَقَالَ: للْبِنْت النّصْف وَللْأُخْت النّصْف وائت ابْنَ مَسْعُودٍ فَسَيُتَابِعُنِي فَسُئِلَ ابْنُ مَسْعُودٍ وَأُخْبِرَ بقول أبي مُوسَى فَقَالَ: لقد ضللت إِذن وَمَا أَنَا مِنَ الْمُهْتَدِينَ أَقْضِي فِيهَا بِمَا قَضَى النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «لِلْبِنْتِ النِّصْفُ وَلِابْنَةِ الِابْنِ السُّدُسُ تَكْمِلَةَ الثُّلُثَيْنِ وَمَا بَقِيَ فَلِلْأُخْتِ» فَأَتَيْنَا أَبَا مُوسَى فَأَخْبَرْنَاهُ بِقَوْلِ ابْنِ مَسْعُودٍ فَقَالَ: لَا تَسْأَلُونِي مَا دَامَ هَذَا الحبر فِيكُم. رَوَاهُ البُخَارِيّ
