"We were headed toward and 'Umar accompanied us as far as Sirar. Then he made ablutions, washing twice, and said: "Do you know why I have accompanied you?" We said: "Yes, we are companions of God's messenger (peace and blessings be upon him)." Then, he said: You will be coming to the people of a town for whom the buzzing of the Qur'an is as the buzzing of bees. Therefore, do not distract them with the Hadiths, and thus engage them. Bare the Qur'an and spare the narration from God's messenger (peace and blessing be upon him)!"
