حَدَّثَنَا أَبُو نُعَيْمٍ، حَدَّثَنَا يُونُسُ، عَنْ أَبِي إِسْحَاقَ، عَنْ عَبْدِ خَيْرٍ
قَالَ رَأَيْتُ عَلِيًّا رَضِيَ اللَّهُ عَنْهُ تَوَضَّأَ وَمَسَحَ عَلَى النَّعْلَيْنِ ثُمَّ قَالَ لَوْلَا أَنِّي رَأَيْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَعَلَ كَمَا رَأَيْتُمُونِي فَعَلْتُ لَرَأَيْتُ أَنَّ بَاطِنَ الْقَدَمَيْنِ هُوَ أَحَقُّ بِالْمَسْحِ مِنْ ظَاهِرِهِمَا
I saw Ali (رضي الله عنه) doing wudoo and wiping over his shoes. Then he said: “If I had not seen the Messenger of Allah (sallallahu alayhi wa sallam) doing what you have seen me do, I would have thought that the bottoms of the feet were more deserving of being wiped than their tops”.
