Musnad Ahmad 30:2685

Yazid narrated to us, Muhammad—meaning Ibn ‘Amr—informed us, from Abu Salamah, from Abu Hurairah, who said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "Ghifar, Aslam, Muzaynah, and whoever was from Juhaynah, are better than the two allies: Asad, Ghatafan, Hawazin, and Tamim. [They are] behind them, for they are the people of horses and camel-hair tents."
