It is narrated about Sayyiduna Zaid bin Thabit (may Allah be pleased with him) that he considered three grandmothers as heirs, two of whom were from the mother's side and one from the father's side.

Sayyiduna Uthman Ghani (may Allah be pleased with him) says: "I bear witness regarding Sayyiduna Abu Bakr Siddiq (may Allah be pleased with him) that he gave the grandfather the status of the father."

Aqil bin Khalid narrates: Saeed bin Sulaiman has reported from his father, from his grandfather Sayyiduna Zaid bin Thabit (may Allah be pleased with him) that once Sayyiduna Umar (may Allah be pleased with him) sought permission to enter his house. He was granted permission (and when he entered, he saw) his head was in the hand of a slave girl who was combing his hair. Sayyiduna Zaid (may Allah be pleased with him) moved his head away, so Sayyiduna Umar (may Allah be pleased with him) said: "Let her comb it." Sayyiduna Zaid (may Allah be pleased with him) said: "O Commander of the Faithful! You could have sent me a message, I would have come to you." So Sayyiduna Umar (may Allah be pleased with him) said: "I have come to you for a matter, I have come to ask about the ruling regarding the grandfather." So Sayyiduna Zaid (may Allah be pleased with him) said: "No! By Allah! What is your opinion about this?" So Sayyiduna Umar (may Allah be pleased with him) said: "There is no revelation about this matter that we may add or subtract anything, this is a matter in which you have to give your opinion. If I find that your opinion matches mine, I will accept it, otherwise there will be no blame on you regarding this." But Sayyiduna Zaid (may Allah be pleased with him) did not accept this, so Sayyiduna Umar (may Allah be pleased with him) left in anger, and he said: "I came here so that you would solve my issue." After that, Sayyiduna Umar (may Allah be pleased with him) came again to Sayyiduna Zaid (may Allah be pleased with him) at the same time as he had come the first day and continued to discuss this matter with him, so Sayyiduna Zaid (may Allah be pleased with him) said: "I will write something for you about this." So he wrote it on a piece of saddlecloth and clarified it with an example: its example is like a tree that grows from a single trunk, from which a branch emerges, then from it another branch emerges, the trunk conveys water to that branch, if the first branch is cut, the water will go to the other branch, and if the second is cut, the water will go to the first branch. Sayyiduna Umar (may Allah be pleased with him) took it and addressed the people and recited to them what was written on that piece, then said: "What Zaid has said about the grandfather, I implement it." The narrator states: Sayyiduna Umar (may Allah be pleased with him) was the first grandfather with whom this situation occurred, he took all the wealth, that is, he took the wealth of his grandson and did not take the wealth of his granddaughters, after that Sayyiduna Umar (may Allah be pleased with him) had that wealth distributed.

It is narrated about Sayyiduna Umar (may Allah be pleased with him) that he gave this ruling: in the presence of full siblings of the deceased, the grandfather will also be a shareholder, no matter how many full siblings there are.

Yunus bin Yazid reports that I asked Zuhri about the inheritance of a person whose survivors include a grandfather and full siblings. Zuhri said: Sa'id bin al-Musayyib, 'Ubaydullah bin 'Abdullah, and Qabisah bin Dhu'ayb have narrated that Sayyiduna 'Umar (may Allah be pleased with him) gave this ruling: the grandfather will share with the full siblings and the siblings from the father's side, provided that taking a share from one-third of the estate is better for him. If the number of siblings is large, then the grandfather will be given one-third, and the rest will be distributed among all the siblings, with the share of one male being equal to that of two females. He also ruled that full siblings have more right than siblings from the father's side, whether they are male or female. However, if siblings from the father's side are present along with full siblings, then they will also receive their share. But siblings from the father's side do not receive anything along with full siblings, except in the case where a brother from the father's side returns (the inheritance) to the full sisters, and after the fixed shares of the full sisters, if anything remains, it will be given to the brothers from the father's side according to the principle that one male receives the share of two females.

Sayyiduna Umar bin Khattab (may Allah be pleased with him) narrates that I heard the Noble Prophet (peace and blessings be upon him) saying: "The killer will not inherit."

Sayyiduna Umar bin Khattab (may Allah be pleased with him) narrates that the Noble Prophet (peace and blessings be upon him) said: "The killer will not receive anything from the inheritance."

The same narration is also transmitted with another chain from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) from the Prophet Muhammad (peace and blessings be upon him).

Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates that the Noble Prophet (peace and blessings be upon him) said: "The killer does not inherit."

Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates that the Noble Prophet (peace and blessings be upon him) said: "The killer does not become the heir (of the murdered)." Abu Abdur Rahman says: The narrator named Ishaq is abandoned in hadith; I have narrated from him among the shaykhs of Layth so that he does not become abandoned in the middle.
