A man came to Prophet ﷺ and said: Messenger of Allah, my sister has taken a vow to perform hajj on foot. The Prophet ﷺ said: Allah gets no good from the affliction your sister imposed on herself, so let her perform hajj riding and make atonement for her oath. (Using translation from Abū Dāʾūd 3295)
جَاءَتِ امْرَأَةٌ إِلَى النَّبِيِّ ﷺ فَقَالَتْ يَا رَسُولَ اللهِ إِنَّ أُخْتِي نَذَرَتْ أَنْ تَحُجَّ مَاشِيَةً؟ قَالَ إِنَّ اللهَ لَا يَصْنَعُ بِشَقَاءِ أُخْتِكِ شَيْئًا لِتَخْرُجْ رَاكِبَةً وَلْتُكَفِّرْ عَنْ يَمِينِهَا
