Malik bin Aws says that once Sayyiduna Ali (may Allah be pleased with him) and Sayyiduna Abbas (may Allah be pleased with him) brought their dispute to Sayyiduna Umar (may Allah be pleased with him) for judgment. Sayyiduna Abbas (may Allah be pleased with him) said, "Decide between me and him regarding such and such matters." The people also said, "Decide between them." Sayyiduna Umar (may Allah be pleased with him) said, "I will not make any decision between the two of them because both of them know that the Messenger of Allah (peace and blessings be upon him) said: 'Inheritance is not established in our property; whatever we leave behind is all charity.'"
