Huzail bin Shurahbeel said: A man came to Abu Musa Ash’ari and Salman bin Rabee’ah and asked both of them about the inheritance shares of a daughter, a son’s daughter (granddaughter), and a full sister. Both of them said: The daughter will get half, and all the remainder is for the sister (because the presence of the daughter blocks the granddaughter). Then they said: Go to Sayyiduna Ibn Mas’ud (may Allah be pleased with him), perhaps he will support our opinion. So the man went to Sayyiduna Abdullah bin Mas’ud (may Allah be pleased with him) and asked him for a ruling about this. He said: If I give such a ruling, I would go astray and would not be among the rightly guided. I only give the ruling as the Messenger of Allah (peace and blessings be upon him) gave: the daughter gets half, the granddaughter gets one-sixth, and whatever remains is for the sister.
Hadith Referenceسنن دارمي / من كتاب الفرائض / 2924
Sayyiduna Abu Musa and Sayyiduna Salman bin Rabi‘ah radi Allahu anhuma considered the granddaughter (son’s daughter) deprived (of inheritance) in the presence of the daughter, but when a similar case was brought before the Messenger of Allah sallallahu alayhi wa sallam, he sallallahu alayhi wa sallam, under «﴿فَإِنْكَانَتَااثْنَتَيْنِفَلَهُمَاالثُّلُثَانِ﴾ [النساء : 176]», gave the granddaughter a sixth (sudus) to complete two-thirds, and what remained was given to the full sister. Sayyiduna Ibn Mas‘ud radi Allahu anhu had heard this decision, so he gave the same ruling.
The case is as follows: Daughter . . . . half . . . . 3 Granddaughter . . . . sixth . . . . 1 Sister . . . . what remains . . . . 2
From this hadith, it is established that the righteous predecessors, the Companions and the Followers (Tabi‘in), respected one another and accepted each other’s opinions, did not impose their own views, and in times of dispute and difference, followed the Sunnah of the Messenger and accepted his sallallahu alayhi wa sallam’s decision, «اللهم أرزقنا اتباع نبيك صلى اللّٰه عليه وسلم.»
