أَخْبَرَنَا أَحْمَدُ بْنُ حَفْصٍ، ‏‏‏‏‏‏قَالَ:‏‏‏‏ حَدَّثَنِي أَبِي، ‏‏‏‏‏‏قَالَ:‏‏‏‏ حَدَّثَنِي إِبْرَاهِيمُ بْنُ طَهْمَانَ، ‏‏‏‏‏‏عَنْ يَحْيَى بْنِ سَعِيدٍ، ‏‏‏‏‏‏عَنْ حُمَيْدٍ الطَّوِيلِ، ‏‏‏‏‏‏عَنْ أَنَسِ بْنِ مَالِكٍ، ‏‏‏‏‏‏قَالَ:‏‏‏‏ أَتَى رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ عَلَى رَجُلٍ يُهَادَى بَيْنَ ابْنَيْهِ، ‏‏‏‏‏‏فَقَالَ:‏‏‏‏ مَا شَأْنُ هَذَا ؟ . فَقِيلَ:‏‏‏‏ نَذَرَ أَنْ يَمْشِيَ إِلَى الْكَعْبَةِ. فَقَالَ:‏‏‏‏ إِنَّ اللَّهَ لَا يَصْنَعُ بِتَعْذِيبِ هَذَا نَفْسَهُ شَيْئًا ، ‏‏‏‏‏‏فَأَمَرَهُ أَنْ يَرْكَبَ.

It was narrated that Anas bin Malik said: The Messenger of Allah came to a man who was being supported by two others and said: 'What is the matter with him?' It was said: 'He vowed to walk to the Ka'bah.' He said: 'Allah does not benefit from his torturing himself.' And he told him to ride.
