وَعَنْ عَبْدِ اللَّهِ بْنِ مَالِكٍ أَنَّ عُقْبَةَ بن عَامر
سَأَلَ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ عَنْ أُخْتٍ لَهُ نَذَرَتْ أَنْ تَحُجَّ حَافِيَةً غَيْرَ مُخْتَمِرَةٍ فَقَالَ: «مُرُوهَا فَلْتَخْتَمِرْ وَلْتَرْكَبْ وَلْتَصُمْ ثَلَاثَةَ أَيَّامٍ»
Abdallah ibn Malik told that when Uqbah ibn Amir consulted the Prophet (sallallahu alayhi wa sallam) about a sister of his who had vowed to perform the Pilgrimage. If barefoot and bareheaded, he said, “Command her to cover her head and to ride, and to fast three days.” Abu Dawud, Tirmidhi, Nasai.
