Chapter 16: The Abrogation Of Inheritance Due To Alliances By Inheritance Due To Relations
Referring to the verse: "Those who believed and adopted exile... As to those who believed but came not into exile": A bedouin (who did not migrate to Medina) did not inherit from an emigrant, and an emigrant did no inherit from him. It was abrogated by the verse: "But kindred by blood have prior rights against each other."
Chapter 17: Regarding Allegiances
The Messenger of Allah (ﷺ) as saying: There is no alliance in Islam, and Islam strengthened the alliance made during pre-Islamic days.
The Messenger of Allah (ﷺ) established an alliance (of brotherhood) between the Emigrants and the Helpers in our house. He was asked: Did not the Messenger of Allah (ﷺ) say: There is no alliance in Islam ? He replied: The Messenger of Allah (ﷺ) established an alliance between the Emigrants and the Helpers in our house. This he said twice or thrice.
Chapter 18: Regarding A Woman Inheriting From The Blood Money Of Her Husband
Sa'id said: Umar ibn al-Khattab said: Blood-money is meant for the clan of the slain, and she will not inherit from the blood-money of her husband. Ad-Dahhak ibn Sufyan said: The Messenger of Allah (ﷺ) wrote to me that I should give a share to the wife of Ashyam ad-Dubabi from the blood-money of her husband. So Umar withdrew his opinion.
Ahmad ibn Salih said: AbdurRazzaq transmitted this tradition to us from Ma'mar, from az-Zuhri on the authority of Sa'id. In this version he said: The Prophet (ﷺ) made him governor over the bedouins.
