Musannaf Ibn Abi Shaybah 12848 — A man or woman obliged to sacrifice

Marwan bin Mahan al-Taymi said: Al-Sha'bi was asked about a woman who had vowed to slaughter a cow: may she sell its hide? He said: Yes. Ibn Ashwa' said: But I do not consider that right. Al-Sha'bi said: Even if you had said its meat (may be sold), there would be no harm in it, for she only vowed its blood, and she has already shed its blood.
