Musannaf Ibn Abi Shayba 27:846

Muhammad ibn al-Hasan al-Asadi narrated to us, he said: Yahya ibn Zakariyya narrated to us, from Sa’d ibn Tariq, he said: Salim ibn Abi al-Ja’d narrated to me that Abu al-Darda’ used to swear by Allah that no tribe would remain except that it would resemble Christianity, except for Qays. O assembly of Muslims, love Qays. O assembly of Muslims, love Qays.
