Bulugh al-Maram, Book 1, Hadith 139 (English) ⓘ

Narrated `Ammar bin Yasir (RAA): The Prophet sent me on some errands and I became junub (sexually impure), and could not find water. I rolled myself in the dirt just as an animal does. I then came to the Prophet and mentioned that to him. He said, "This would have been enough for you," and he struck the earth with his hands once, then he wiped the right hand with the left one, and the outside of the palms of his hands and his face. [Agreed upon. The wording is that of Muslim's].

وَعَنْ عَمَّارِ بْنِ يَاسِرٍ رَضِيَ اَللَّهُ عَنْهُمَا قَالَ: { بَعَثَنِي اَلنَّبِيُّ ‏- صلى الله عليه وسلم ‏-فِي حَاجَةٍ, فَأَجْنَبْتُ, فَلَمْ أَجِدِ اَلْمَاءَ, فَتَمَرَّغْتُ فِي اَلصَّعِيدِ كَمَا تَمَرَّغُ اَلدَّابَّةُ, ثُمَّ أَتَيْتُ اَلنَّبِيَّ ‏- صلى الله عليه وسلم ‏-فَذَكَرْتُ ذَلِكَ لَهُ, فَقَالَ: "إِنَّمَا كَانَ يَكْفِيكَ أَنْ تَقُولَ بِيَدَيْكَ هَكَذَا" ثُمَّ ضَرَبَ بِيَدَيْهِ اَلْأَرْضَ ضَرْبَةً وَاحِدَةً, ثُمَّ مَسَحَ اَلشِّمَالَ عَلَى اَلْيَمِينِ, وَظَاهِرَ كَفَّيْهِ وَوَجْهَهُ } مُتَّفَقٌ عَلَيْهِ, وَاللَّفْظُ لِمُسْلِم ٍ (156)‏.‏ ‏1 ‏- صحيح.‏ رواه البخاري (347)‏، ومسلم (368)‏.‏
