Musannaf Ibn Abi Shayba 16:540

Abu Bakr narrated to us, he said: Yunus bin Muhammad narrated to us, from Salam bin Abi Muti’, he said: Ibn Husayn narrated to me, from al-Sha’bi, he said: I went out with Abu Wa’il until we came to the furriers. He bought a fur, and the owner of the fur said: "I will tell you more, O Abu Wa’il, it is slaughtered (dhabiha/tazkiyah)." He said: "It would not please me if I had bought what you said for a qirat." Ibn Husayn said: Ibrahim used to say that, and Sa’id bin Jubayr used to say that.
