Musannaf Ibn Abi Shaybah 33119 — A wife and both parents: from how

Sayyiduna Abdullah (may Allah be pleased with him) said: Whenever Sayyiduna Umar (may Allah be pleased with him) adopted an opinion and we, following him, adopted that opinion, we found it easy. He was asked about the issue of a wife and parents inheriting, and he gave the wife a quarter and the mother a third of the remaining estate, and he ordered that the rest of the estate be given to the father.
