مسند امام احمد بن حنبل · Hadith 363

It was narrated that Juwairiyyah bin Qudamah said: I did Hajj and I came to Madinah the year 'Umar was stabbed. He gave a speech and said: I dreamt that a red rooster pecked me once or twice - Shu'bah was not certain and what happened was that he was stabbed. The people were given permission to enter upon him. The first ones to enter upon him were the Companions of the Prophet (PBUH), then the people of Madinah, then the people of Syria. Then permission was given to the people of Iraq, and I was among those who entered upon him. Every time people entered upon him, they praised him and wept. When we entered upon him, he had wrapped his stomach with a black turban cloth, and blood was flowing. We said: Give us some advice; and no one asked him for advice except us. He said: You have to adhere to the Book of Allah, for you will never go astray so long as you follow it. We said: Advise us. He said: I urge you to be kind to the Muhajireen, for the people will increase in number and they will decrease. And I advise you to be kind to the Ansar, for they are the people of Islam with whom Islam sought refuge. And I advise you to be kind to the Bedouin, for they are your origin and your strength. And I advise you be kind to the non-Muslim people under your rule (ahludh-dhimmah), for they have a covenant with your Prophet and they give you a source of income. You may leave now. And he did not say any more to us than these words, Muhammad bin Ja'far said: Shu'bah said: Then after that I asked him and he said concerning the Bedouin: I advise you to be kind to the Bedouin, for they are your brothers and the enemy of your enemy.
