Tanah itu suci dan tidak najis tanah bisa dipakai untuk tayamum, dan dapat menyucikan junub
Imam Nasa'i : 318أَخْبَرَنَا مُحَمَّدُ بْنُ الْعَلَاءِ قَالَ حَدَّثَنَا أَبُو مُعَاوِيَةَ قَالَ حَدَّثَنَا الْأَعْمَشُ عَنْ شَقِيقٍ قَالَكُنْتُ جَالِسًا مَعَ عَبْدِ اللَّهِ وَأَبِي مُوسَى فَقَالَ أَبُو مُوسَى أَوْ لَمْ تَسْمَعْ قَوْلَ عَمَّارٍ لِعُمَرَ بَعَثَنِي رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فِي حَاجَةٍ فَأَجْنَبْتُ فَلَمْ أَجِدْ الْمَاءَ فَتَمَرَّغْتُ بِالصَّعِيدِ ثُمَّ أَتَيْتُ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَذَكَرْتُ ذَلِكَ لَهُ فَقَالَ إِنَّمَا كَانَ يَكْفِيكَ أَنْ تَقُولَ هَكَذَا وَضَرَبَ بِيَدَيْهِ عَلَى الْأَرْضِ ضَرْبَةً فَمَسَحَ كَفَّيْهِ ثُمَّ نَفَضَهُمَا ثُمَّ ضَرَبَ بِشِمَالِهِ عَلَى يَمِينِهِ وَبِيَمِينِهِ عَلَى شِمَالِهِ عَلَى كَفَّيْهِ وَوَجْهِهِفَقَالَ عَبْدُ اللَّهِ أَوَ لَمْ تَرَ عُمَرَ لَمْ يَقْنَعْ بِقَوْلِ عَمَّارٍ
Narrated to us [Muhammad bin Al 'Alla] he said :Narrated to us [Abu Mu'awiyah] he said :Narrated to us [Al A'masy] from [Syaqiq], he said, "I sat with Abdullah and Abu Musa. [Abu Musa] then said, 'Have you not heard what [Ammar] said to Umar, "The Messenger of Allah peace be upon him once sent me when he needed something, then I was junub and did not get water, so I rolled on the ground. Then I came to Rasulullah peace be upon him and mentioned this to him. Then he said, 'It is enough for you to say this'. Then the Prophet peace be upon him slapped his hands on the ground once, then he rubbed his palms together, then shook them and slapped his left palm against his right palm, and slapped his right palm against his left palm, then rubbed his palms and his face?" Abdullah said, 'Didn't you see Umar who was dissatisfied with Ammar's words?'
