Musannaf Ibn Abi Shaybah 33318 — When he leaves brothers

Alqamah said: Sayyiduna Abdullah (may Allah be pleased with him) used to make the grandfather a partner with the brothers, but when the brothers were many he would have him given one third of the estate. Ibrahim, the narrator, said: When Alqamah died, I came to Ubaydah, and he told me that Sayyiduna Ibn Mas'ud (may Allah be pleased with him) used to make the grandfather a partner with the brothers, and when the brothers were many he would have him given one sixth of the estate. He said: On hearing this I returned from him with a heavy heart. Then I passed by Ubayd bin Nadilah, and he asked me: "What is the matter? Why this listlessness in you?" I said: "Why should it not be so, when such a thing has happened?" Then I related the whole matter to him. He said: "Both of them told you the truth." I said: "How excellent you are! How did both of them tell the truth?" He said: "The opinion of Sayyiduna Abdullah (may Allah be pleased with him) was that the grandfather should be made a partner with the brothers, and when they increased he should be given one sixth of the estate. Then he came to Sayyiduna Umar (may Allah be pleased with him) and saw that he would make the grandfather a partner with the brothers, and when the brothers increased he would have the grandfather given one third of the estate. So he abandoned his own opinion and began to act upon the opinion of Sayyiduna Umar (may Allah be pleased with him)."
