"Do you remember when we were on a campaign, and I became Junub and rolled in the dust, then I came to the Prophet ﷺ and he said: 'This would have been sufficient.'" (One of the narrators) Shu'bah struck his hands on his knees and blew into his hands, then he wiped his face and palms with them once. (Using translation from Nasāʾī 317)  

عَمَّارٌ أَمَا تَذْكُرُ حَيْثُ كُنَّا فِي سَرِيَّةٍ فَأَجْنَبْتُ فَتَمَعَّكْتُ فِي التُّرَابِ فَأَتَيْتُ رَسُولَ اللهِ ﷺ فَقَالَ إِنَّمَا يَكْفِيكَ هَكَذَا وَضَرَبَ شُعْبَةُ بِيَدَيْهِ عَلَى رُكْبَتَيْهِ وَنَفَخَ فِي يَدَيْهِ وَمَسَحَ بِهِمَا وَجْهَهُ وَكَفَّيْهِ مَرَّةً وَاحِدَةً
