"Abdullah bin Yasar the freed slave of Maimunah, and I came and entered upon Abu Juhaim bin Al-Harith bin Al-Sammah Al-Ansari. Abu Juhaim said: 'The Messenger of Allah ﷺ came back from the direction of Bi'r Al-jamal and was met by a man who greeted him with Salam, but the Messenger of Allah ﷺ did not return the greeting until he turned to the wall and wiped his face and hands, then he returned the greeting.'"  

أَبُو جُهَيْمٍ أَقْبَلَ رَسُولُ اللَّهِ ﷺ مِنْ نَحْوِ بِئْرِ الْجَمَلِ وَلَقِيَهُ رَجُلٌ فَسَلَّمَ عَلَيْهِ فَلَمْ يَرُدَّ رَسُولُ اللَّهِ ﷺ حَتَّى أَقْبَلَ عَلَى الْجِدَارِ فَمَسَحَ بِوَجْهِهِ وَيَدَيْهِ ثُمَّ رَدَّ عَلَيْهِ السَّلاَمَ  

The Messenger of Allah ﷺ came from the privy. A man met him near Bir Jamal and saluted him. The Messenger of Allah ﷺ did not return the salutation until he came to a wall and placed his hands on the wall and wiped his face and hands; he then returned the man's salutation.  

أَقْبَلَ رَسُولُ اللَّهِ ﷺ مِنَ الْغَائِطِ فَلَقِيَهُ رَجُلٌ عِنْدَ بِئْرِ جَمَلٍ فَسَلَّمَ عَلَيْهِ فَلَمْ يَرُدَّ عَلَيْهِ رَسُولُ اللَّهِ ﷺ حَتَّى أَقْبَلَ عَلَى الْحَائِطِ فَوَضَعَ يَدَهُ عَلَى الْحَائِطِ ثُمَّ مَسَحَ وَجْهَهُ وَيَدَيْهِ ثُمَّ رَدَّ رَسُولُ اللَّهِ ﷺ عَلَى الرَّجُلِ السَّلاَمَ  

The Prophet ﷺ came from the direction of Bir Jamal. A man met him and greeted him. But he did not return back the greeting till he went to a (mud) wall and wiped his face and hands with its dust (performed Tayammum) and then returned back the greeting. (Using translation from Bukhārī 337)  

أَقْبَلْتُ أَنَا وَعَبْدُ اللهِ بْنُ يَسَارٍ مَوْلَى مَيْمُونَةَ زَوْجِ النَّبِيِّ ﷺ دَخَلْنَا عَلَى أَبِي جُهَيْمِ بْنِ الْحَارِثِ بْنِ الصِّمَّةِ الْأَنْصَارِيِّ قَالَ أَبُو جُهَيْمٍ أَقْبَلَ رَسُولُ اللهِ ﷺ مِنْ نَحْوِ بِئْرِ جَمَلٍ فَلَقِيَهُ رَجُلٌ فَسَلَّمَ عَلَيْهِ فَلَمْ يَرُدَّ عَلَيْهِ رَسُولُ اللهِ ﷺ حَتَّى أَقْبَلَ عَلَى الْجِدَارِ فَمَسَحَ بِوَجْهِهِ وَيَدَيْهِ ثُمَّ رَدَّ عَلَيْهِ رَسُولُ اللهِ ﷺ  

[Machine] The Messenger of Allah ﷺ went out for one of his needs towards the well of Jamel, then a man from his companions met him and greeted him, but the Messenger of Allah ﷺ did not reply to him until he placed his hand on the wall, then he wiped his face and hands, and then he said, "And peace be upon you."  

خَرَجَ رَسُولُ اللهِ ﷺ لِبَعْضِ حَاجَتِهِ نَحْوَ بِئْرِ جَمَلٍ ثُمَّ أَقْبَلَ فَلَقِيَهُ رَجُلٌ مِنْ أَصْحَابِهِ فَسَلَّمَ عَلَيْهِ فَلَمْ يَرُدَّ عَلَيْهِ رَسُولُ اللهِ ﷺ حَتَّى وَضَع يَدَهُ عَلَى الْجِدَارِ ثُمَّ مَسَحَ وَجْهَهُ وَيَدَيْهِ ثُمَّ قَالَ وَعَلَيْكَ السَّلَامُ
