One of the heirs acknowledging a brother or a sister: what does he get?

Al-A'mash narrates that Ibrahim said, concerning the man whose being a brother is acknowledged by one of several brothers while the rest deny it, that this brother will share with them in the inheritance, just as with a slave jointly owned by several brothers when one of them frees his share.

He said: Amir and al-Hakam and their companions used to say: He enters only into the share of the one who acknowledged him.

Ibn Jurayj said: A man from the people of San'a informed me that Tawus gave a ruling concerning the four sons of one father, one of whom testified that his father had acknowledged the lineage of a slave of his who was shared among them. Tawus did not give effect to the acknowledgment of his lineage; rather, he gave the slave one-fifth of the inheritance from the property of the man who had testified that his father had acknowledged his lineage, and he freed the slave from the property of that witness.

Ibn Sirin narrates that Shurayh said, concerning the man who acknowledged the lineage of a brother, that his testimony is that he is his brother.

Mansur narrates that Ibrahim said, concerning the man who acknowledges the lineage of a brother or sister, that his acknowledgment has no standing until all the heirs acknowledge that he is his brother.

Waki' said: When two brothers are the heirs, and one of them acknowledges a man as a brother while the other denies it, Ibn Abi Layla used to say concerning it: This case is worked out from six shares: three shares for the one who did not acknowledge the lineage, two shares for the one claiming it, and one share for the one on whose behalf the claim was made.

He said: Abu Hanifah says: This case is worked out from four shares: two shares for the one who did not make the claim, one share for the one making the claim, and one share for the one on whose behalf the claim was made.
