Musannaf Ibn Abi Shayba 33:1337

Ibn Numayr narrated to us, from Malik ibn Mighwal, from Akil, who said: There was something between a man from the tribe and Abd al-Rahman ibn Yazid. Alqama said to him, "Would you insult me if I insulted you?" He said, "No." He said, "He is better than me, and he is more [engaged in] jihad than me."
