A man came to 'Umar bin khattab and said: "I became impure following sexual emission and cannot find any water." 'Umar said to him: "Do not pray." But 'Ammar bin Yasir said: "Do you not remember, O Commander of the Believers, when you and I were on a military expedition and we became sexually impure and could not find water? As for you, you did not pray, but I rolled in the dust and then prayed. When I came to the Prophet and told him what had happened, he said: 'It would have been enough for you (to do this).' (Then demonstrating) the Prophet struck the ground with his hands, then blew on hem, and wiped his face and palms with them."  

إِنِّي أَجْنَبْتُ فَلَمْ أَجِدِ الْمَاءَ فَقَالَ عُمَرُ لاَ تُصَلِّ فَقَالَ عَمَّارُ بْنُ يَاسِرٍ أَمَا تَذْكُرُ يَا أَمِيرَ الْمُؤْمِنِينَ إِذْ أَنَا وَأَنْتَ فِي سَرِيَّةٍ فَأَجْنَبْنَا فَلَمْ نَجِدِ الْمَاءَ فَأَمَّا أَنْتَ فَلَمْ تُصَلِّ وَأَمَّا أَنَا فَتَمَعَّكْتُ فِي التُّرَابِ فَصَلَّيْتُ فَلَمَّا أَتَيْتُ النَّبِيَّ ﷺ فَذَكَرْتُ ذَلِكَ لَهُ فَقَالَ إِنَّمَا كَانَ يَكْفِيكَ وَضَرَبَ النَّبِيُّ ﷺ بِيَدَيْهِ إِلَى الأَرْضِ ثُمَّ نَفَخَ فِيهِمَا وَمَسَحَ بِهِمَا وَجْهَهُ وَكَفَّيْهِ  

They asked 'Abdullah bin Abi Awfa about dry ablution. He said: "The Prophet commanded 'Ammar to do like this;' and he struck the ground with his palms, shook the dust off and wiped his face. (Da'if)Hakam said, "and his hands," Salamah said, "and his elbows."  

أَمَرَ النَّبِيُّ ﷺ عَمَّارًا أَنْ يَفْعَلَ هَكَذَا وَضَرَبَ بِيَدَيْهِ إِلَى الأَرْضِ ثُمَّ نَفَضَهُمَا وَمَسَحَ عَلَى وَجْهِهِ قَالَ الْحَكَمُ وَيَدَيْهِ وَقَالَ سَلَمَةُ وَمِرْفَقَيْهِ
