Jabir (may Allah be pleased with him) said: I said: "O Messenger of Allah (peace and blessings be upon him)! Is Umrah obligatory, and is it a duty like the duty of Hajj?" He (peace and blessings be upon him) said: "No, but if you perform Umrah, it is better for you."
The Ubaydullah (in this chain) is Ubaydullah bin al-Mughirah, and he alone narrated it from Abu al-Zubayr. This text is known only through al-Hajjaj bin Artat, from Muhammad bin al-Munkadir, from Jabir.
