(23) باب مَنْ رَأَى عَلَيْهِ كَفَّارَةً إِذَا كَانَ فِي مَعْصِيَةٍ
Narrated Ibn 'Abbas:
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).
