Dawud bin Abi Hind reports about Umar bin Abdul Aziz that he used to make the living heirs of the dead, and he did not make those who drowned heirs of one another.

Qatadah says that in the letter of Hazrat Umar bin Abdul Aziz (may Allah have mercy on him) it was stated that every person will be the heir of that individual among the people who is his heir.

A’mash narrates that a woman came to Ibrahim and said: My brother and my nephew were traveling in a boat when both drowned; you did not make either of them an heir to anything.

Mughira narrates that Ibrahim said: Neither of the two will inherit from the other the wealth which he inherited from him.

Muammar narrates from Zuhri about those people who die together in such a way that it is not known which of them died before the other; he said that they will not be made heirs of one another.

Ibrahim narrates that Hazrat Ali (may Allah be pleased with him) made three men, who drowned while traveling in a boat, heirs to one another, even though their mother was alive, and made their mother the heir of one-sixth from each of them. Then, from the inheritance that was given to each of the brothers from the other, one-third of the wealth was given to the mother, and the remaining wealth was given to the 'asaba (residuary heirs).

Muhammad bin Salim says that I heard Ibrahim and Sha'bi (may Allah have mercy on them) explaining this matter: "Those who drowned should be made heirs of one another." They said that when one of the two heirs dies leaving behind wealth and the other dies without leaving any wealth, then the heirs of the one who did not leave any wealth will inherit from the one who left wealth, and the one who left wealth will not receive anything.

Mughira narrates the statement of Ibrahim that the ruling regarding the inheritance of a child found on the road is the same as that of wealth found on the road.

Zaid bin Wahb narrates that Hazrat Ali (may Allah be pleased with him) stoned a woman, and then said to the heirs of that woman: "This is your son; you will be his heirs and he will be your heir, and if he commits any crime, its compensation will be upon you."

Shu'bi narrates that Hazrat Ali (may Allah be pleased with him) and Abdullah (may Allah be pleased with him) said regarding the son of the woman who performed li'an that his mother and his mother's 'asaba are his 'asaba, and the ruling for the child of adultery (illegitimate) is the same.
