Musnad Ahmad 25:440

'Affan narrated to us, Hammam narrated to us, Qatadah informed us, from 'Ikrimah, from Ibn 'Abbas: That 'Uqbah ibn 'Amir came to the Prophet, may Allah bless him and grant him peace, and said: "My sister has vowed to walk to the House (the Ka'bah)." He said: "Indeed, Allah, the Almighty and Majestic, is in no need of your sister's vow. Let her perform Hajj riding, and let her offer a sacrificial animal."
