كتاب الفرائض

Chapter 22: If someone is converted to Islam through somebody else
That Aisha, the mother of the Believers, intended to buy a slave girl in order to manumit her. The slave girl's master said, "We are ready to sell her to you on the condition that her Wala should be for us." Aisha mentioned that to Allah's Messenger (ﷺ) who said, "This (condition) should not prevent you from buying her, for the Wala is for the one who manumits (the slave)."
Chapter 23: What a woman can inherit of the Wala’ (in the book it is given women)

Chapter 29: Whoever claims to be the son of a person other than his father
The Prophet (ﷺ) said, "Do not deny your fathers (i.e. claim to be the sons of persons other than your fathers), and whoever denies his father, is charged with disbelief."
Chapter 30: If a lady claims to be the mother of a son
Allah's Messenger (ﷺ) said, "There were two women with whom there were their two sons. A wolf came and took away the son of one of them. That lady said to her companion, 'The wolf has taken your son.' The other said, 'But it has taken your son.' So both of them sought the judgment of (the Prophet) David who judged that the boy should be given to the older lady. Then both of them went to (the Prophet) Solomon, son of David and informed him of the case. Solomon said, 'Give me a knife so that I may cut the child into two portions and give one half to each of you.' The younger lady said, 'Do not do so; may Allah bless you ! He is her child.' On that, he gave the child to the younger lady." Abu Huraira added: By Allah! I had never heard the word 'Sakkin' as meaning knife, except on that day, for we used to call it "Mudya".
Chapter 14: “They ask you for a legal verdict. Say: ‘Allah directs about Al-Kalalah…”
The last Qur'anic Verse that was revealed (to the Prophet) was the final Verse of Surat-an-Nisa, i.e., 'They ask you for a legal verdict Say: Allah directs (thus) About those who leave No descendants or ascendants as heirs....' (4.176)
Chapter 21: The sin of the freed slave who denies his master who has freed him.
We have no Book to recite except the Book of Allah (Qur'an) and this paper. Then `Ali took out the paper, and behold ! There was written in it, legal verdicts about the retaliation for wounds, the ages of the camels (to be paid as Zakat or as blood money). In it was also written: 'Medina is a sanctuary from Air (mountain) to Thaur (mountain). So whoever innovates in it an heresy (something new in religion) or commits a crime in it or gives shelter to such an innovator, will incur the curse of Allah, the angels and all the people, and none of his compulsory or optional good deeds will be accepted on the Day of Resurrection. And whoever (a freed slave) takes as his master (i.e. be-friends) some people other than hi real masters without the permission of his real masters, will incur the curse of Allah, the angels and all the people, and none of his compulsory, or optional good deeds will be accepted on the Day of Resurrection. And the asylum granted by any Muslim is to be secured by all the Muslims, even if it is granted by one of the lowest social status among them; and whoever betrays a Muslim, in this respect will incur the curse of Allah, the angels, and all the people, and none of his Compulsory or optional good deeds will be accepted on the Day of Resurrection."
