Sayyiduna Uqbah bin Amir (may Allah be pleased with him) said: My sister vowed that she would walk on foot to the House of Allah, and she told me to seek a ruling for her. So I asked the Prophet (peace and blessings be upon him) about it, and he (peace and blessings be upon him) said: "Let her walk and let her also ride."
The narrator said: Abu al-Khayr never parted from Sayyiduna Uqbah (may Allah be pleased with him).
