Uqbah consulted the Prophet ﷺ about his sister who took a vow to perform hajj barefooted and bareheaded. So he said: Command her to cover her head and to ride, and to fast three days.
أَنَّهُ سَأَلَ النَّبِيَّ ﷺ عَنْ أُخْتٍ لَهُ نَذَرَتْ أَنْ تَحُجَّ حَافِيَةً غَيْرَ مُخْتَمِرَةٍ فَقَالَ مُرُوهَا فَلْتَخْتَمِرْ وَلْتَرْكَبْ وَلْتَصُمْ ثَلاَثَةَ أَيَّامٍ
