(12) CHAPTER. The sisters (of the deceased) share the inheritance with the daughters (of the deceased), the sisters being treated as the Asaba.
Narrated Al-Aswad: Mu`adh bin Jabal gave this verdict for us in the lifetime of Allah's Apostle. One-half of the inheritance is to be given to the daughter and the other half to the sister. Sulaiman said: Mu`adh gave a verdict for us, but he did not mention that it was so in the lifetime of Allah's Apostle.
Narrated Huzail: `Abdullah said, The judgment I will give in this matter will be like the judgment of the Prophet, i.e. one-half is for the daughter and one-sixth for the son's daughter and the rest of the inheritance for the sister.
