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.  

أَقْبَلْتُ أَنَا وَعَبْدُ اللَّهِ بْنُ يَسَارٍ مَوْلَى مَيْمُونَةَ زَوْجِ النَّبِيِّ ﷺ حَتَّى دَخَلْنَا عَلَى أَبِي جُهَيْمِ بْنِ الْحَارِثِ بْنِ الصِّمَّةِ الأَنْصَارِيِّ فَقَالَ أَبُو الْجُهَيْمِ أَقْبَلَ النَّبِيُّ ﷺ مِنْ نَحْوِ بِئْرِ جَمَلٍ فَلَقِيَهُ رَجُلٌ فَسَلَّمَ عَلَيْهِ فَلَمْ يَرُدَّ عَلَيْهِ النَّبِيُّ ﷺ حَتَّى أَقْبَلَ عَلَى الْجِدَارِ فَمَسَحَ بِوَجْهِهِ وَيَدَيْهِ ثُمَّ رَدَّ عَلَيْهِ السَّلاَمَ  

I and 'Abd al-Rahmin b. Yasir, the freed slave of Maimuna, the wife of the Apostle (way peace be upon him). came to the house of Abu'l-Jahm b. al-Harith al-Simma Ansari and he said: The Messenger of Allah ﷺ came from the direction of Bi'r Jamal and a man met him; he saluted him but the Messenger of Allah ﷺ made no response, till he (the Holy Prophet) came to the wall, wiped his face and hands and then returned his salutations.  

أَنَّهُ سَمِعَهُ يَقُولُ أَقْبَلْتُ أَنَا وَعَبْدُ الرَّحْمَنِ بْنُ يَسَارٍ مَوْلَى مَيْمُونَةَ زَوْجِ النَّبِيِّ ﷺ حَتَّى دَخَلْنَا عَلَى أَبِي الْجَهْمِ بْنِ الْحَارِثِ بْنِ الصِّمَّةِ الأَنْصَارِيِّ فَقَالَ أَبُو الْجَهْمِ أَقْبَلَ رَسُولُ اللَّهِ ﷺ مِنْ نَحْوِ بِئْرِ جَمَلٍ فَلَقِيَهُ رَجُلٌ فَسَلَّمَ عَلَيْهِ فَلَمْ يَرُدَّ رَسُولُ اللَّهِ ﷺ عَلَيْهِ حَتَّى أَقْبَلَ عَلَى الْجِدَارِ فَمَسَحَ وَجْهَهُ وَيَدَيْهِ ثُمَّ رَدَّ عَلَيْهِ السَّلاَمَ  

"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  

I and 'Abd Allah b. Yasar, the freed slave of Maimunah, wife of the Prophet ﷺ, came and entered upon Abu al-Juhaim b. al-Harith b. al-Simmat al-Ansari. Abu al-Juhaim said: The Messenger of Allah ﷺ came from Bir Jamal (a place near Medina) and a man met him and saluted him. The Messenger of Allah ﷺ did not return the salutation until he came to a wall and wiped his face and hands and then returned the salutation (i.e. after performing tayammum).  

أَنَّهُ سَمِعَهُ يَقُولُ أَقْبَلْتُ أَنَا وَعَبْدُ اللَّهِ بْنُ يَسَارٍ مَوْلَى مَيْمُونَةَ زَوْجِ النَّبِيِّ ﷺ حَتَّى دَخَلْنَا عَلَى أَبِي الْجُهَيْمِ بْنِ الْحَارِثِ بْنِ الصِّمَّةِ الأَنْصَارِيِّ فَقَالَ أَبُو الْجُهَيْمِ أَقْبَلَ رَسُولُ اللَّهِ ﷺ مِنْ نَحْوِ بِئْرِ جَمَلٍ فَلَقِيَهُ رَجُلٌ فَسَلَّمَ عَلَيْهِ فَلَمْ يَرُدَّ رَسُولُ اللَّهِ ﷺ عَلَيْهِ السَّلاَمَ حَتَّى أَتَى عَلَى جِدَارٍ 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  

"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.'" (Using translation from Nasāʾī 311)  

أَبُو الْجُهَيْمِ أَقْبَلَ رَسُولُ اللَّهِ ﷺ مِنْ نَحْوِ بِئْرِ الْجَمَلِ فَلَقِيَهُ رَجُلٌ فَسَلَّمَ عَلَيْهِ فَلَمْ يَرُدَّ رَسُولُ اللَّهِ ﷺ حَتَّى أَقْبَلَ عَلَى الْجِدَارِ فَمَسَحَ بِوَجْهِهِ وَيَدَيْهِ ثُمَّ رَدَّ السَّلَامَ  

"عَنْ أَبِى الجَهم بْنِ الَحارِثِ بِنِ الصُّمةِ الأسَدِيِّ قَالَ: أقْبَلَ رَسُولُ الله ﷺ مِنْ نَحْوِ بِير حَمِيل فَلَقِيَهُ رَجُل فَسَلَّمَ عَلَيْهِ فَلَمْ يَرُدَّ رسُولُ الله ﷺ حَتَّى أقْبَلَ عَلَى الَجِدارِ فَمسحَ بِوَجْهِهِ ويَديْهِ، ثُمَّ رَدَّ عَلَيْه السَّلَامَ".
