Musannaf Ibn Abi Shaybah

Hazrat Ibn Abbas (may Allah be pleased with them both) narrates that the delegation of the tribe of Abdul Qais came to the service of the Noble Prophet (peace and blessings be upon him). The Messenger of Allah (peace and blessings be upon him) said: "Which tribe's delegation is this?" or he said: "Who are you people?" The companions (may Allah be pleased with them) replied: "They are people from the tribe of Rabi'ah." The Prophet (peace and blessings be upon him) said: "Welcome to these people," or he said, "Welcome to the delegation. There is neither disgrace for you in this world nor shame in the Hereafter." Then they said: "O Messenger of Allah! We have come to you from a very distant place, and since there is the tribe of the disbelievers of Mudar between us and you, we can only come to you in those months in which fighting is forbidden. Therefore, grant us such commands that distinguish between truth and falsehood, so that we may act upon them ourselves and also inform those whom we have left behind in our homeland. And by acting upon them, we may enter Paradise." The narrator says: The Prophet (peace and blessings be upon him) commanded them regarding four things and forbade them from four things; he (peace and blessings be upon him) commanded them to have faith in one Allah. And he said: "Do you know what it means to have faith in Allah?" They replied: "Allah and His Messenger know best." The Prophet (peace and blessings be upon him) said: "To bear witness that there is no god but Allah and that Muhammad is the Messenger of Allah, to establish prayer, to give zakat, and to fast in Ramadan." (And the Prophet, peace and blessings be upon him, commanded a fifth thing in addition to the four:) "To give one-fifth (khums) from the spoils of war." Then he said: "Remember these things and inform those whom you have left behind."
