Musannaf Ibn Abi Shayba 17:1207

Yazid ibn Harun narrated to us, he said: Al-Awam ibn Hawshab informed us, he said: I met with Iyas ibn Mu'awiyah at Dhat 'Irq, and we mentioned Ibrahim al-Taymi. Iyas said: "Were it not for his honor in my sight, I would have praised him." I said: "Do you know him?" He said: "Yes." I said: "Then why do you dislike praising him?" He said: "It used to be said that praise is part of the recompense."
