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
