The Prophet (ﷺ) said: Knowledge has three categories; anything else is extra; a precise verse, or an established sunnah (practice), or a firm obligatory duty.

I fell ill, and the Prophet (ﷺ) and Abu Bakr came to me on foot to visit me. As I was unconscious, I could not speak to him. He performed ablution and sprinkled water on me ; so I became conscious. I said: Messenger of Allah, how should I do in my property, as I have sisters? Thereafter the verse about inheritance was revealed: "They ask you for legal decision. Say: Allah directs (thus) about those who leave no descendants or ascendants as heirs."

I fell ill, and I had seven sisters. The Messenger of Allah (ﷺ) came to me and blew on my face. So I became conscious. I said: Messenger of Allah, may I not bequeath one-third of my property to my sisters? He replied: Do good. I asked: Half? He replied: Do good. He then went out and left me, and said: I do not think, Jabir, you will die of this disease. Allah has revealed (verses) and described the share of your sisters. He appointed two-thirds for them. Jabir used to say: This verse was revealed about me: "They ask you for a legal decision. Say: Allah directs (thus) about those who leave no descendants or ascendants as heirs.

The last verse revealed about the decease who left no descendants or ascendants: "They ask you for the legal decision. Say: Allah directs (thus) about those who leave no descendants or ascendants as heirs."

A man came to the Prophet (ﷺ) and said: Messenger of Allah, they ask you for a legal decision about a kalalah. What is meant by kalalah? He replied: The verse revealed in summer is sufficient for you. I asked Abu Ishaq: Does it mean a person who dies and leaves neither children nor father? He said: This is so. The people think it is so.

A man came to Abu Musa al-Ash'ari and Salman b. Rabi'ah, and asked about a case where there were a daughter, a son's daughter and full sister. They replied: The daughter gets half and the full gets half. The son's daughter gets nothing. Go to Ibn Mas'ud and you will find that he agrees with me. So the man came to him and informed him about their opinion. He said: I would then be in error and not be one of those who are rightly guided. But I decide concerning the matter as the Messenger of Allah (ﷺ) did: The daughter gets half, and the son's daughter gets a share which complete thirds (i.e. gets a sixth), and what remain to the full sister."

We went out with the Messenger of Allah (ﷺ) and came to a woman of the Ansar in al-Aswaf. The woman brought her two daughters, and said: Messenger of Allah, these are the daughters of Thabit ibn Qays who was killed as a martyr when he was with you at the battle of Uhud, their paternal uncle has taken all their property and inheritance, and he has not left anything for them. What do you think, Messenger of Allah? They cannot be married unless they have some property. The Messenger of Allah (ﷺ) said: Allah will decide regarding the matter. Then the verse of Surat an-Nisa was revealed: "Allah (thus) directs you as regards your children's (inheritance)." Messenger of Allah (ﷺ) said: Call to me the woman and her husband's brother. He then said to their paternal uncle: Give them two-thirds and their mother an eighth, and what remains is yours. Abu Dawud said: The narrator Bishr made a mistake. They were the daughters of Sa'd b. al-Rabi' for Thabit b. Qais was killed in the battle of Yamamah.

The wife of Sa'd b. al-Rabi said: Messenger of Allah, Sa'd died and left two daughters. He then narrated the rest of the tradition in a similar way. Abu Dawud said: This is the most correct tradition.

Mu'adh b. Jabal gave shares of inheritance to a sister and a daughter. He gave each of them half. He was at Yemen while the Prophet (ﷺ) was alive.
