What is the matter with him? They said: He had taken the vow to walk (on foot to the Ka'ba). Thereupon he (Allah's Apoitle) said: Allah is indifferent to his inflicting upon himself chastisement, and he commanded him to ride.  

أَنَّ النَّبِيَّ ﷺ رَأَىَ شَيْخًا يُهَادَى بَيْنَ ابْنَيْهِ فَقَالَ مَا بَالُ هَذَا قَالُوا نَذَرَ أَنْ يَمْشِيَ قَالَ إِنَّ اللَّهَ عَنْ تَعْذِيبِ هَذَا نَفْسَهُ لَغَنِيٌّ وَأَمَرَهُ أَنْ يَرْكَبَ  

Allah's Apostle ﷺ found an old man walking between his two sons supported by them, whereupon Allah's Apostle ﷺ said: What is the matter with him? He (the narrator) said: Messenger of Allah, they are his sons and there is upon him the (fulfilment) of the vow, whereupon Allah's Apostle ﷺ said: Ride, old man, for Allah is not in need of you and your vow.  

أَنَّ النَّبِيَّ ﷺ أَدْرَكَ شَيْخًا يَمْشِي بَيْنَ ابْنَيْهِ يَتَوَكَّأُ عَلَيْهِمَا فَقَالَ النَّبِيُّ ﷺ مَا شَأْنُ هَذَا قَالَ ابْنَاهُ يَا رَسُولَ اللَّهِ كَانَ عَلَيْهِ نَذْرٌ فَقَالَ النَّبِيُّ ﷺ ارْكَبْ أَيُّهَا الشَّيْخُ فَإِنَّ اللَّهَ غَنِيٌّ عَنْكَ وَعَنْ نَذْرِكَ وَاللَّفْظُ لِقُتَيْبَةَ وَابْنِ حُجْرٍ  

This hadith has been narrated on the authority of 'Amr b. Abu 'Amr with the same chain of transmitters.  

عَنْ عَمْرِو بْنِ أَبِي عَمْرٍو بِهَذَا الإِسْنَادِ مِثْلَهُ  

My sister took a vow that she would walk bare foot to the house of Allah (Ka'ba). She asked me to inquire from Messenger of Allah ﷺ about it. I sought his decision and he said: She should walk on foot and ride also.  

أَنْ تَمْشِيَ إِلَى بَيْتِ اللَّهِ حَافِيَةً فَأَمَرَتْنِي أَنْ أَسْتَفْتِيَ لَهَا رَسُولَ اللَّهِ ﷺ فَاسْتَفْتَيْتُهُ فَقَالَ لِتَمْشِ وَلْتَرْكَبْ
