Musannaf Ibn Abi Shaybah 32908 — One who bequeaths the like of one

Awf said: I was present with Hisham bin Hubayrah when he gave a ruling concerning a man who, at the time of his death, willed to his sister wealth equal to the share of two of his children, and his heirs included both sons and daughters. The sister for whom the will was made wished to count herself equal to the male children, while the heirs wished to give her a share equal to that of the female children. He ruled that this sister would be treated as equal to the female children, if he did not state it clearly.
