Sunan an-Nasai Book 1, Hadith 319

أَخْبَرَنَا عَبْدُ اللَّهِ بْنُ مُحَمَّدِ بْنِ تَمِيمٍ، قَالَ حَدَّثَنَا حَجَّاجٌ، قَالَ حَدَّثَنَا شُعْبَةُ، عَنِ الْحَكَمِ، وَسَلَمَةُ، عَنْ ذَرٍّ، عَنِ ابْنِ عَبْدِ الرَّحْمَنِ بْنِ أَبْزَى، عَنْ أَبِيهِ، أَنَّ رَجُلاً، جَاءَ إِلَى عُمَرَ - رضى الله عنه - فَقَالَ إِنِّي أَجْنَبْتُ فَلَمْ أَجِدِ الْمَاءَ ‏.‏ فَقَالَ عُمَرُ لاَ تُصَلِّ ‏.‏ فَقَالَ عَمَّارٌ أَمَا تَذْكُرُ يَا أَمِيرَ الْمُؤْمِنِينَ إِذْ أَنَا وَأَنْتَ فِي سَرِيَّةٍ فَأَجْنَبْنَا فَلَمْ نَجِدْ مَاءً فَأَمَّا أَنْتَ فَلَمْ تُصَلِّ وَأَمَّا أَنَا فَتَمَعَّكْتُ فِي التُّرَابِ ثُمَّ صَلَّيْتُ فَلَمَّا أَتَيْنَا رَسُولَ اللَّهِ صلى الله عليه وسلم ذَكَرْتُ ذَلِكَ لَهُ فَقَالَ ‏ "‏ إِنَّمَا يَكْفِيكَ ‏"‏ ‏.‏ وَضَرَبَ النَّبِيُّ صلى الله عليه وسلم بِيَدَيْهِ إِلَى الأَرْضِ ثُمَّ نَفَخَ فِيهِمَا فَمَسَحَ بِهِمَا وَجْهَهُ وَكَفَّيْهِ - شَكَّ سَلَمَةُ وَقَالَ لاَ أَدْرِي فِيهِ إِلَى الْمِرْفَقَيْنِ أَوْ إِلَى الْكَفَّيْنِ - قَالَ عُمَرُ نُوَلِّيكَ مِنْ ذَلِكَ مَا تَوَلَّيْتَ قَالَ شُعْبَةُ كَانَ يَقُولُ الْكَفَّيْنِ وَالْوَجْهَ وَالذِّرَاعَيْنِ ‏.‏ فَقَالَ لَهُ مَنْصُورٌ مَا تَقُولُ فَإِنَّهُ لاَ يَذْكُرُ الذِّرَاعَيْنِ أَحَدٌ غَيْرُكَ ‏.‏ فَشَكَّ سَلَمَةُ فَقَالَ لاَ أَدْرِي ذَكَرَ الذِّرَاعَيْنِ أَمْ لاَ ‏.‏

It was narrated from Ibn 'Abdur-Rahman bin Abza, from his father, that a man came to 'Umar, may Allah be please with him, and said:"I have become Junub and I cannot find any water." 'Umar said: "Do not pray." 'Ammar said: "Do you not remember, O Commander of the Believers, when you and I were on a campaign and became Junub, and we could not find any water. You did not pray, but I rolled in the dust then prayed. When we came to the Messenger of Allah (ﷺ) I told him about that and he said: 'This would have been sufficient for you,' and then Prophet (ﷺ) struck the earth with his hands then blew on them and wiped his face and hands - (one of the narrators) Salamah was uncertain and said: "I do not know if he said it should be up to the elbows or just the hands." - 'Umar said: "We will let you bear the burden of what you took upon yourself." (One of the narrators) Shu'bah said: "He used to say the hands, face and forearms." (Another) Mansur said to him: "What are you saying? No one mentions the forearms except you." Salamah was not certain and said: "I do not know whether he mentioned the forearms or not
