The tradition about the sister of 'Uqbah b. 'Amir as narrated by Hisham, but he made no mention of the sacrificial animal. In his version he said: Ask your sister to ride.

Abu Dawud said: Khalid narrated it from 'Ikrimah to the same effect as narrated by Hisham.
Sunan Abi Dawud Book 22, Hadith 57
← Previous Hadith That when the Prophet (ﷺ) was informed that the sister of 'Uqbah b. 'Amir had taken a vow to perform Hajj on foot, he said: Allah is not in need of her vow. So ask her to ride.

Abu Dawud said: Sa'ib b. 'Arubah has transmitted a similar tradition. Khalid has also transmitted a similar tradition on the authority of 'Ikrimah from the Prophet (ﷺ).

Sunan Abi Dawud Book 22, Hadith 56 Next Hadith → My sister took a vow to walk on foot to the House of Allah (i.e. Ka'bah). She asked me to consult the Prophet (ﷺ) about her. So I consulted the Prophet (ﷺ). He said: Let her walk and ride.
