It is narrated from Abdullah bin Malik (may Allah be pleased with him) that the sister of Hazrat Uqbah bin Amir (may Allah be pleased with him) had vowed to perform Hajj on foot without wearing a shawl. Hazrat Uqbah (may Allah be pleased with him) asked the Prophet (peace and blessings be upon him) about this, so the Prophet (peace and blessings be upon him) said: What will Allah do with her hardship? Instruct her to wear a shawl, ride (an animal), and fast for three days.
