Arabic hadith text
حَدَّثَنَا يَعْقُوبُ بْنُ حُمَيْدِ بْنِ كَاسِبٍ، حَدَّثَنَا عَبْدُ الْعَزِيزِ بْنُ مُحَمَّدٍ، عَنْ عَمْرِو بْنِ أَبِي عَمْرٍو، عَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ، قَالَ رَأَى النَّبِيُّ ـ صلى الله عليه وسلم ـ شَيْخًا يَمْشِي بَيْنَ ابْنَيْهِ فَقَالَ ‏"‏ مَا شَأْنُ هَذَا ‏"‏ ‏.‏ قَالَ ابْنَاهُ نَذْرٌ يَا رَسُولَ اللَّهِ ‏.‏ قَالَ ‏"‏ ارْكَبْ أَيُّهَا الشَّيْخُ فَإِنَّ اللَّهَ غَنِيٌّ عَنْكَ وَعَنْ نَذْرِكَ ‏"
Translation
It was narrated that Abu Hurairah said

"The Prophet (ﷺ) saw an old man walking between his two sons, and he said: What is the matter with him?' His sons said: 'A vow, O Messenger of Allah.' He said: 'Let this old man ride, for Allah has no need of you or your vow."'
