Abu Jamrah Nasr bin Imran al-Duba'i (may Allah have mercy on him) says: I said to Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both): I have a jar of sweet nabidh which I drink; when I drink a lot of it and sit with people and the gathering becomes long, I fear that I will be disgraced. He said to me: The delegation of Abd al-Qays came, and he (peace and blessings be upon him) said: "Welcome to the delegation who are neither disgraced (nor regretful)." They said: "O Messenger of Allah (peace and blessings be upon him), between us and you lies the tribe of the disbelievers of Mudar, so we cannot come to you except in a sacred month. So command us with a matter which we may act upon and to which we may invite those we have left behind." He (peace and blessings be upon him) said: "I command you to believe. Do you know what belief is? It is to bear witness that there is no god but Allah and that Muhammad (peace and blessings be upon him) is the Messenger of Allah, and that you establish the prayer, pay zakah, fast in Ramadan and perform Hajj to the House of Allah." The narrator says: I think he (peace and blessings be upon him) also said: "And that you give one fifth (khumus) of the spoils of war. And I forbid you from drinking from earthen jars, gourds, pitch-coated vessels and hollowed wooden vessels."
