Hadith 12:26
Anas said that the Prophet saw an old man being supported between his sons, and on asking what was the matter with him and being told that he had taken a vow to walk,* he said, “God most high has no need that this man should punish himself,” and he ordered him to ride. In a version by Muslim on Abu Huraira’s authority he said, “Ride, old man, for God is not in need of you and your vow.” * Mirqat , iii, 565 explains this as a vow to walk to the Ka’ba. (Bukhari and Muslim).
وَعَنْ أَنَسٍ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ رَأَى شَيْخًا يُهَادَى بَيْنَ ابْنَيْهِ فَقَالَ: «مَا بَالُ هَذَا؟» قَالُوا: نَذَرَ أَنْ يَمْشِيَ إِلَى بَيت الله قَالَ: «إِنَّ اللَّهَ تَعَالَى عَنْ تَعْذِيبِ هَذَا نَفسه لَغَنِيّ» . وَأمره أَن يركب وَفِي رِوَايَةٍ لِمُسْلِمٍ عَنْ أَبِي هُرَيْرَةَ قَالَ: «ارْكَبْ أَيُّهَا الشَّيْخُ فَإِنَّ اللَّهَ غَنِيٌّ عَنْكَ وَعَن نذرك»
