ذِكْرُ الْبَيَانِ بِأَنَّ مَسْحَ الْمُصْطَفَى ﷺ عَلَى النَّعْلَيْنِ كَانَ ذَلِكَ فِي وُضُوءِ النَّفْلِ دُونَ الْوُضُوءِ الَّذِي يَجِبُ مِنْ حَدَثٍ مَعْلُومٍ
We prayed Zuhr with ‘Ali ؓ , then he went to a gathering that he used to hold in ar-Rahbah. He sat and we sat around him, then the time for ‘Asr came. A vessel (of water) was brought to him. He took a handful from it and rinsed his mouth and nose, and he wiped his face and forearms, and he wiped his head, and he wiped his feet. Then he stood up and drank what was left over in the vessel. Then he said: I have been told that some men dislike anyone to drink whilst standing, but I saw the Messenger of Allah ﷺ do what I have done. (Using translation from Aḥmad 1366)
صَلَّيْتُ مَعَ عَلِيٍّ رِضْوَانُ اللَّهِ عَلَيْهِ الظُّهْرَ ثُمَّ انْطَلَقَ إِلَى مَجْلِسٍ كَانَ يَجْلِسُهُ فِي الرَّحَبَةِ فَقَعَدَ وَقَعَدْنَا حَوْلَهُ حَتَّى حَضَرَتِ الْعَصْرُ فَأُتِيَ بِإِنَاءٍ فِيهِ مَاءٌ فَأَخَذَ مِنْهُ كَفًّا فَتَمَضْمَضَ وَاسْتَنْشَقَ وَمَسَحَ وَجْهَهُ وَذِرَاعَيْهِ وَمَسَحَ بِرَأْسِهِ وَمَسَحَ بِرِجْلَيْهِ ثُمَّ قَامَ فَشَرِبَ فَضْلَ مَائِهِ ثُمَّ قَالَ إِنِّي حُدِّثْتُ أَنَّ رِجَالًا يَكْرَهُونَ أَنْ يَشْرَبَ أَحَدُهُمْ وَهُوَ قَائِمٌ «وَإِنِّي رَأَيْتُ رَسُولَ اللَّهِ ﷺ فَعَلَ كَمَا فَعَلْتُ وَهَذَا وُضُوءُ مَنْ لَمْ يُحْدِثْ»
