"I was siting with 'Abdullah and Abu Musa, and Abu Musa said: 'Have you not heard what 'Ammar said to 'Umar: 'The Messenger of Allah ﷺ sent me on an errand and I became Junub, and I could not find water, so I rolled in the earth then I came to the Prophet ﷺ and told him about.' He said: 'It would have been sufficient for you to do this,' and he struck the earth with his hands, then wiped his hands, then knocked them together to remove the dust, then he wiped his right hand with his left and his left hand with his right, palm to palm, and wiped his face.'" Then 'Abdullah said: "Did you not see that 'Umar was not convinced by what 'Ammar said?" (Using translation from Nasāʾī 320)   

تَسْمَعْ قَوْلَ عَمَّارٍ لِعُمَرَ بَعَثَنِي رَسُولُ اللهِ ﷺ فِي حَاجَةٍ فَأَجْنَبْتُ فَلَمْ أَجِدِ الْمَاءَ فَتَمَرَّغْتُ بِالصَّعِيدِ ثُمَّ أَتَيْتُ رَسُولَ اللهِ ﷺ فَذَكَرْتُ ذَلِكَ لَهُ فَقَالَ «إِنَّمَا كَانَ يَكْفِيكَ أَنْ تَقُولَ هَكَذَا» ثُمَّ ضَرَبَ بِيَدِهِ عَلَى الْأَرْضِ ضَرْبَةً وَاحِدَةً فَمَسَحَ كَفَّهُ ثُمَّ نَفَضَهَا ثُمَّ ضَرَبَ بِشِمَالِهِ عَلَى يَمِينِهِ وَبِيَمِينِهِ عَلَى شِمَالِهِ عَلَى كَفَّيْهِ وَوَجْهِهِ قَالَ عَبْدُ اللهِ أَوَلَمْ تَرَ عُمَرَ لَمْ يَقْنَعْ بِقَوْلِ عَمَّارٍ  

"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.'" (Using translation from Nasāʾī 313)  

أَجْنَبْتُ وَأَنَا فِي الْإِبِلِ فَلَمْ أَجِدْ مَاءً فَتَمَعَّكْتُ تَمَعُّكَ الدَّابَّةِ فَأَتَيْتُ رَسُولَ اللهِ ﷺ فَأَخْبَرْتُهُ بِذَلِكَ فَقَالَ «إِنَّمَا كَانَ يُجْزِيكَ مِنْ ذَلِكَ التَّيَمُّمِ»
