It is narrated from Qabisah bin Dhu'ayb that after the passing of the Messenger of Allah (peace and blessings be upon him), a grandmother came to Sayyiduna Abu Bakr al-Siddiq (may Allah be pleased with him) and said: I have a right (of inheritance), because my grandson (son's son, or daughter's son) has died. Abu Bakr al-Siddiq (may Allah be pleased with him) said: "I do not find any fixed right for you in the Book of Allah, nor have I heard anything from the Messenger of Allah (peace and blessings be upon him) about it; however, I will ask the people." Then Sayyiduna al-Mughirah bin Shu'bah (may Allah be pleased with him) testified that the Messenger of Allah (peace and blessings be upon him) had given the grandmother one-sixth (1/6). Abu Bakr al-Siddiq (may Allah be pleased with him) asked: "Has anyone else heard this along with you?" Then Sayyiduna Muhammad bin Maslamah (may Allah be pleased with him) also testified, so Abu Bakr al-Siddiq (may Allah be pleased with him) gave her one-sixth. This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it.

It is narrated from Abu Salamah that a man came to Sayyiduna Ibn Abbas (may Allah be pleased with them both) and asked: A man has died and left his daughter and his full sister (so what is the ruling on the inheritance)? He said: "The daughter gets half, and the sister gets nothing." The man said: Sayyiduna Umar (may Allah be pleased with him) gave a ruling contrary to this, that the daughter gets half and the sister also gets half! Sayyiduna Ibn Abbas (may Allah be pleased with them both) said: "Do you know better, or Allah?" (The narrator says:) I did not understand the reason for this until I met Ibn Tawus. I mentioned this hadith of al-Zuhri to him, and he told me that his father heard Sayyiduna Ibn Abbas (may Allah be pleased with them both) say: Allah, the Mighty and Majestic, says: "If a man dies having no child, and he has a sister, then for her is half of what he left" [Surah al-Nisa: 176] . What Ibn Abbas (may Allah be pleased with them both) meant was that you people have fixed half for the sister even when the deceased has a child (a daughter). This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it.
