Sha'bi (may Allah have mercy on him) narrates that Qarza intended to go to Iraq with some people from Banu Abd al-Ashhal. Umar bin Khattab (may Allah be pleased with him) also set out with them, requested water, performed ablution, and said: "Do you know why I have come out with you?" They said: "Because of your love for us and our right." He said: "Indeed, you have a right, but I have come to say one thing: narrate few ahadith from the Prophet (peace and blessings be upon him), and I am your partner in this (adherence)." (Sha'bi) said: "After this statement of Umar (may Allah be pleased with him), I would not narrate hadith from the Prophet (peace and blessings be upon him)."
