"Abdullah bin Yasar the freed slave of Maimunah, and I came and entered upon Abu Juhaim bin Al-Harith bin Al-Sammah Al-Ansari. Abu Juhaim said: 'The Messenger of Allah ﷺ came back from the direction of Bi'r Al-jamal and was met by a man who greeted him with Salam, but the Messenger of Allah ﷺ did not return the greeting until he turned to the wall and wiped his face and hands, then he returned the greeting.'"  

أَبُو جُهَيْمٍ أَقْبَلَ رَسُولُ اللَّهِ ﷺ مِنْ نَحْوِ بِئْرِ الْجَمَلِ وَلَقِيَهُ رَجُلٌ فَسَلَّمَ عَلَيْهِ فَلَمْ يَرُدَّ رَسُولُ اللَّهِ ﷺ حَتَّى أَقْبَلَ عَلَى الْجِدَارِ فَمَسَحَ بِوَجْهِهِ وَيَدَيْهِ ثُمَّ رَدَّ عَلَيْهِ السَّلاَمَ  

"I have become Junub and I do not have any water." 'Umar said: "Do not pray." But 'Ammar bin Yasir said: "O Commander of the Believers! Don't you remember when you and I were on a campaign and we became Junub and could not find water? You did not pray, but I rolled in the dust and prayed. Then we came to the Prophet ﷺ and told him about that, and he said: 'It would have been sufficient for you (to do this),' then the Prophet ﷺ struck his hands on the ground and blew on them, then wiped his face and hands with them'" - (one of the narrators) Salamah was uncertain and did not know whether that was up to the elbows or just hands. And 'Umar said: "We will let you bear the burden of what you took upon yourself."  

إِنِّي أَجْنَبْتُ فَلَمْ أَجِدِ الْمَاءَ قَالَ عُمَرُ لاَ تُصَلِّ فَقَالَ عَمَّارُ بْنُ يَاسِرٍ يَا أَمِيرَ الْمُؤْمِنِينَ أَمَا تَذْكُرُ إِذْ أَنَا وَأَنْتَ فِي سَرِيَّةٍ فَأَجْنَبْنَا فَلَمْ نَجِدِ الْمَاءَ فَأَمَّا أَنْتَ فَلَمْ تُصَلِّ وَأَمَّا أَنَا فَتَمَعَّكْتُ فِي التُّرَابِ فَصَلَّيْتُ فَأَتَيْنَا النَّبِيَّ ﷺ فَذَكَرْنَا ذَلِكَ لَهُ فَقَالَ إِنَّمَا كَانَ يَكْفِيكَ فَضَرَبَ النَّبِيُّ ﷺ يَدَيْهِ إِلَى الأَرْضِ ثُمَّ نَفَخَ فِيهِمَا ثُمَّ مَسَحَ بِهِمَا وَجْهَهُ وَكَفَّيْهِ وَسَلَمَةُ شَكَّ لاَ يَدْرِي فِيهِ الْمِرْفَقَيْنِ أَوْ إِلَى الْكَفَّيْنِ فَقَالَ عُمَرُ نُوَلِّيكَ مَا تَوَلَّيْتَ  

"I became Junub while I was on a camel and I could not find any water, so I rolled in the dust like an animal. I came to the Messenger of Allah ﷺ and told him about that, and he said: 'Tayammum would have been sufficient for you.'"  

أَجْنَبْتُ وَأَنَا فِي الإِبِلِ فَلَمْ أَجِدْ مَاءً فَتَمَعَّكْتُ فِي التُّرَابِ تَمَعُّكَ الدَّابَّةِ فَأَتَيْتُ رَسُولَ اللَّهِ ﷺ فَأَخْبَرْتُهُ بِذَلِكَ فَقَالَ إِنَّمَا كَانَ يَجْزِيكَ مِنْ ذَلِكَ التَّيَمُّمُ
