It is narrated from Sayyidah Maymunah (may Allah be pleased with her) that the Prophet (peace and blessings be upon him) passed by a dead sheep belonging to a slave woman of ours, which had been given to her as charity, and he (peace and blessings be upon him) said: "What harm would there be for the people of this house if they took its skin, tanned it and made use of it?" They said: O Messenger of Allah, it is carrion. He (peace and blessings be upon him) said: "Only eating it is forbidden."
It was said to Sufyan that Ma'mar does not say "and tanned it" in this narration, and that he says al-Zuhri used to reject (the mention of) tanning. Sufyan said: But I have memorised this word, and what we pointed to is the sentence that others also transmitted: "Only eating it is forbidden." Sufyan would sometimes not mention Maymunah in it, and when he paused over this chain to consider it, he would mention Maymunah in it.
