Musannaf Ibn Abi Shaybah 33111 — A wife and both parents: from how

Ibrahim said: Sayyiduna Abdullah (may Allah be pleased with him) was asked about the shares of a wife and parents, and he said: "Whatever path Sayyiduna Umar (may Allah be pleased with him) took, when we took that path we found it smooth. A case of a wife and parents was brought to him, and he divided the estate into four shares, giving the wife a quarter and the mother a third of what remained, and he gave all the rest to the father."
