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.
