510 - Abd al-Malik ibn Abd al-Hamid informed us that he said to Abu Abd Allah: "If someone says: 'Abu Bakr and Umar' and remains silent, and does not mention Uthman, is he considered complete in the Sunnah?" He reacted with astonishment and said: "Would he be complete in the Sunnah?"—meaning, he would not be complete in the Sunnah.
