Hasan narrates that Hazrat Umar once said: "Who among you knows the decision of the Messenger of Allah (peace and blessings be upon him) regarding the grandfather?" So, Ma'qil bin Yasar Al-Muzani said: "The Prophet (peace and blessings be upon him) gave a decision about one of our men." Hazrat Umar asked: "About what?" He replied: "About the sixth share." Hazrat Umar said: "Who will testify to this with you?" Ma'qil said: "I do not know anyone." He (Umar) said: "You do not know! Then what is the benefit?"
