Musannaf Ibn Abi Shayba 26:166

Ibn Fudayl narrated to us, from Bassam, from Fudayl ibn ‘Amr, who said: Ibrahim said: Six women inherit: his daughter, his son’s daughter, his mother, his grandmother, his sister, and his wife. And the woman inherits from seven: her son, her son’s son, her father, her grandfather, her husband, and her brother. And he inherits one-sixth from her daughter’s son, but he does not inherit anything from her, according to the statement of all of them.
