(on the authority of his father who said) ʿAmmar said so (the above Statement). And Shuʿba stroked lightly the earth with his hands and brought them close to his mouth (blew off the dust) and passed them over his face and then the backs of his hands. ʿAmmar said, "Ablution (meaning Tayammum here) is sufficient for a Muslim if water is not available."  

عَمَّارٌ بِهَذَا وَضَرَبَ شُعْبَةُ بِيَدَيْهِ الأَرْضَ ثُمَّ أَدْنَاهُمَا مِنْ فِيهِ ثُمَّ مَسَحَ وَجْهَهُ وَكَفَّيْهِ وَقَالَ النَّضْرُ أَخْبَرَنَا شُعْبَةُ عَنِ الْحَكَمِ قَالَ سَمِعْتُ ذَرًّا يَقُولُ عَنِ ابْنِ عَبْدِ الرَّحْمَنِ بْنِ أَبْزَى قَالَ الْحَكَمُ وَقَدْ سَمِعْتُهُ مِنِ ابْنِ عَبْدِ الرَّحْمَنِ عَنْ أَبِيهِ قَالَ قَالَ عَمَّارٌ  

that while he was in the company of ʿUmar, ʿAmmar said to ʿUmar, "We were in a detachment and became Junub and I blew the dust off my hands (performed the rolling over the earth and prayed.)"  

وَقَالَ لَهُ عَمَّارٌ كُنَّا فِي سَرِيَّةٍ فَأَجْنَبْنَا وَقَالَ تَفَلَ فِيهِمَا  

ʿAmmar said to ʿUmar "I rolled myself in the dust and came to the Prophet ﷺ who said, 'Passing dusted hands over the face and the backs of the hands is sufficient for you.' "  

عَمَّارٌ لِعُمَرَ تَمَعَّكْتُ فَأَتَيْتُ النَّبِيَّ ﷺ فَقَالَ يَكْفِيكَ الْوَجْهُ وَالْكَفَّانِ  

As above.  

لَهُ عَمَّارٌ وَسَاقَ الْحَدِيثَ  

The Prophet ﷺ stroked the earth with his hands and then passed them over his face and the backs of his hands (while demonstrating Tayammum).  

عَمَّارٌ فَضَرَبَ النَّبِيُّ ﷺ بِيَدِهِ الأَرْضَ فَمَسَحَ وَجْهَهُ وَكَفَّيْهِ
