"Abu Rifa'ah said: 'I came to the Messenger of Allah [SAW] while he was delivering a Khutbah, and said: "O Messenger of Allah, a stranger has come to ask about his religion, for he does not know what his religion is." The Messenger of Allah [SAW] stopped delivering his Khutbah and turned to me. A chair was brought, and I think its legs were of iron. The Messenger of Allah [SAW] sat down on it and started to teach me what Allah has taught him, then he went and completed his Khutbah.'" (Using translation from Nasāʾī 5377)   

أَبُو رِفَاعَةَ الْعَدَوِيُّ انْتَهَيْتُ إِلَى رَسُولِ اللهِ ﷺ وَهُوَ يَخْطُبُ فَقُلْتُ يَا رَسُولَ اللهِ رَجُلٌ غَرِيبٌ جَاءَ يَسْأَلُ عَنْ دِينِهِ لَا يَدْرِي مَا دِينُهُ؟ قَالَ فَجَاءَ رَسُولُ اللهِ ﷺ وَتَرَكَ خُطْبَتَهُ ثُمَّ أَتَى بِكُرْسِيٍّ خِلْتُ قَوَائِمَهُ حَدِيدًا فَصَعِدَ رَسُولُ اللهِ ﷺ فَجَعَلَ يُعَلِّمُنِي مِمَّا عَلَّمَهُ اللهُ ثُمَّ أَتَى خُطْبَتَهُ فَأَتَمَّهَا  

[Machine] "I saw the Messenger of Allah ﷺ perform ablution. He began by washing his face and both his arms. Then, he rinsed his mouth and nose. Finally, he wiped his head."  

«رَأَيْتُ رَسُولَ اللهِ ﷺ يَتَوَضَّأُ فَبَدَأَ فَغَسَلَ وَجْهَهُ وَذِرَاعَيْهِ ثُمَّ تَمَضْمَضَ وَاسْتَنْشَقَ ثُمَّ مَسَحَ بِرَأْسِهِ»
