Sahih al-Bukhari, Hadith 341 ⓘ
Narrated `Abdur Rahman bin Abza: `Ammar said to `Umar "I rolled myself in the dust and came to the Prophet who said, 'Passing dusted hands over the face and the backs of the hands is sufficient for you.' "
حَدَّثَنَا مُحَمَّدُ بْنُ كَثِيرٍ، أَخْبَرَنَا شُعْبَةُ، عَنِ الْحَكَمِ، عَنْ ذَرٍّ، عَنِ ابْنِ عَبْدِ الرَّحْمَنِ بْنِ أَبْزَى، عَنْ عَبْدِ الرَّحْمَنِ، قَالَ قَالَ عَمَّارٌ لِعُمَرَ تَمَعَّكْتُ فَأَتَيْتُ النَّبِيَّ صلى الله عليه وسلم فَقَالَ " يَكْفِيكَ الْوَجْهُ وَالْكَفَّانِ " .
