It is narrated from Huzail bin Shurahbeel that a man came to Sayyiduna Abu Musa Ash’ari (may Allah be pleased with him) and Sayyiduna Salman bin Rabee’ (may Allah be pleased with him) and asked them: Among the heirs are a daughter, a granddaughter (son’s daughter), and a uterine sister. They said: Half of the estate will go to the daughter and half to the sister, and go to Sayyiduna Ibn Mas’ud (may Allah be pleased with him), he will also agree with our verdict. But when the questioner went to Sayyiduna Ibn Mas’ud (may Allah be pleased with him) and informed him of their verdict, Sayyiduna Ibn Mas’ud (may Allah be pleased with him) said: If I also decide in this way, I will have gone astray from the right path; I will give the verdict of the Messenger of Allah (peace and blessings be upon him), and that is: half to the daughter, one-sixth to the granddaughter, so that two-thirds are completed, and whatever remains will go to the sister.

It is narrated from Sayyiduna Ali (may Allah be pleased with him), he says: You people recite this verse that (the inheritance will be distributed) after the bequest made by the deceased or the debt, whereas the Messenger of Allah (peace and blessings be upon him) ordered that the debt be paid before executing the bequest, and he also decided that (when full siblings and maternal siblings are together) the full siblings will be the heirs, not the maternal siblings. A man will inherit from his full brother, not from his maternal brother.

It is narrated from Sayyiduna Qabeesah bin Dhu’ayb (may Allah be pleased with him) that a grandmother came to Sayyiduna Abu Bakr (may Allah be pleased with him) and demanded her share of inheritance, but he said: I do not know of any evidence in the Book of Allah or the Sunnah of the Messenger of Allah (peace and blessings be upon him) regarding your right. However, I will inquire about this from the people. Then he (may Allah be pleased with him) asked the people, and Sayyiduna Mugheerah bin Shu’bah (may Allah be pleased with him) said: I heard the Messenger of Allah (peace and blessings be upon him) say that he allotted one-sixth for the grandmother. Sayyiduna Abu Bakr (may Allah be pleased with him) said: Who will testify to this with you? Then Sayyiduna Muhammad bin Maslamah (may Allah be pleased with him) stood up and said the same thing as Sayyiduna Mugheerah (may Allah be pleased with him) had said. Thus, Sayyiduna Abu Bakr (may Allah be pleased with him) allotted this share for her.

(Second chain) In this it is: Sayyiduna Muhammad bin Maslamah (may Allah be pleased with him) stood up and said: I was present with the Messenger of Allah (peace and blessings of Allah be upon him), and he (peace be upon him) decreed one-sixth for the grandmother, so Sayyiduna Abu Bakr (may Allah be pleased with him) enforced one-sixth for her.

It is narrated from Sayyiduna Ubadah bin Samit (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) decided to give both the paternal grandmother and the maternal grandmother an equal share of one-sixth each from the inheritance.

Narrated by Sayyiduna Imran bin Husain (may Allah be pleased with him): A man came to the service of the Noble Prophet (peace and blessings be upon him) and said: My grandson has passed away, what will I receive from his inheritance? The Prophet (peace and blessings be upon him) said: For you is one-sixth. When he turned to leave, the Prophet (peace and blessings be upon him) called him back and said: You will also get one-sixth. Then when he was about to leave, the Prophet (peace and blessings be upon him) called him back and said: This one-sixth is extra for you, (it is not given as a share).

It is also narrated from Sayyiduna Imran bin Husain (may Allah be pleased with him) that Sayyiduna Umar (may Allah be pleased with him) said: I beseech by Allah the person who has heard any hadith from the Messenger of Allah (peace and blessings be upon him) regarding the inheritance of the grandfather, to tell me. A man stood up and said: Yes, I was present with the Noble Prophet (peace and blessings be upon him), and he (peace be upon him) gave him (the grandfather) one third share. He (Umar) asked: With which heirs? He replied: That I do not know. He (Umar) said: Then you have not understood.

It is narrated from Amr bin Maymoon that he was present with Sayyiduna Umar (may Allah be pleased with him). He (may Allah be pleased with him) gathered the companions during his life and in a state of health, and asked them by invoking Allah, "Has anyone heard any hadith from the Messenger of Allah (peace and blessings be upon him) regarding the inheritance of the grandfather?" Sayyiduna Ma'qil bin Yasar (may Allah be pleased with him) stood up and said: "I heard from the Messenger of Allah (peace and blessings be upon him) that a case was brought to him in which there was a grandfather, so he (peace and blessings be upon him) gave the grandfather one-sixth or one-third share." Sayyiduna Umar (may Allah be pleased with him) asked: "What was that case, i.e., who were the individuals involved in that case?" He said: "That I do not know." He (may Allah be pleased with him) said: "What prevented you from knowing that?"

It is narrated from Hasan Basri (may Allah have mercy on him) that Sayyiduna Umar bin Khattab (may Allah be pleased with him) inquired from the people about the prescribed share of the grandfather in inheritance. Sayyiduna Ma'qil bin Yasar Muzani (may Allah be pleased with him) said: Regarding this, the Messenger of Allah (peace and blessings be upon him) had given a ruling. He asked: What was it? He replied: The Prophet (peace and blessings be upon him) had given one-sixth. Sayyiduna Umar (may Allah be pleased with him) asked: With which individuals? He replied: That I do not know. Sayyiduna Umar (may Allah be pleased with him) said: Then you have not understood the issue; how will this suffice you?

It is narrated from Saeed bin Jubair, he says: I was sitting with Abdullah bin Utbah bin Masood, whom Sayyiduna Ibn Zubair (may Allah be pleased with them both) had entrusted with the office of judge. He received this letter from Sayyiduna Ibn Zubair (may Allah be pleased with them both): Peace be upon you. To proceed! You have written to me regarding the inheritance of the grandfather, so I submit that the Messenger of Allah (peace and blessings be upon him) said that if I were to take anyone from this Ummah as a close friend (Khalil), I would have chosen Ibn Abi Quhafah, but he is my religious brother and companion of the cave. And Sayyiduna Abu Bakr Siddiq (may Allah be pleased with him) considered the grandfather as standing in place of the father, and the statement of Sayyiduna Abu Bakr Siddiq (may Allah be pleased with him) is more deserving that we act upon it.
