It is narrated from Amr bin Maymoon that he was present with Sayyiduna Umar (may Allah be pleased with him). He (may Allah be pleased with him) gathered the companions during his life and in a state of health, and asked them by invoking Allah, "Has anyone heard any hadith from the Messenger of Allah (peace and blessings be upon him) regarding the inheritance of the grandfather?" Sayyiduna Ma'qil bin Yasar (may Allah be pleased with him) stood up and said: "I heard from the Messenger of Allah (peace and blessings be upon him) that a case was brought to him in which there was a grandfather, so he (peace and blessings be upon him) gave the grandfather one-sixth or one-third share." Sayyiduna Umar (may Allah be pleased with him) asked: "What was that case, i.e., who were the individuals involved in that case?" He said: "That I do not know." He (may Allah be pleased with him) said: "What prevented you from knowing that?"
