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. (Using translation from Muslim 1643a)
أَنَّ رَسُولَ اللهِ ﷺ أَدْرَكَ شَيْخًا يَمْشِي بَيْنَ ابْنَيْهِ يَتَوَكَّأُ عَلَيْهِمَا فَقَالَ النَّبِيُّ ﷺ مَا شَأْنُ هَذَا الشَّيْخِ؟ قَالَ ابْنَاهُ كَانَ عَلَيْهِ نَذْرٌ فَقَالَ النَّبِيُّ ﷺ ارْكَبْ أَيُّهَا الشَّيْخُ فَإِنَّ اللهَ ﷻ غَنِيٌّ عَنْكَ وَعَنْ نَذْرِكَ لَفْظُهُمَا سَوَاءٌ
