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)
جَاءَ رَجُلَ إِلَى النَّبِيِّ ﷺ فَقَالَ يَا رَسُولَ اللهِ إِنَّ أُخْتِي نَذَرَتْ أَنْ تَحُجَّ مَاشِيَةً فَقَالَ إِنَّ اللهَ لَا يَصْنَعُ بِشَقَاءِ أُخْتِكَ شَيْئًا لِتَحُجَّ رَاكِبَةً ثُمَّ تُكَفِّرَ يَمِينَهَا تَفَرَّدَ بِهِ شَرِيكٌ الْقَاضِي
