Sahih al-Bukhari, Hadith 246 ⓘ
Narrated Ibn 'Umar: The Prophet said, "I dreamt that I was cleaning my teeth with a Siwak and two persons came to me. One of them was older than the other and I gave the Siwak to the younger. I was told that I should give it to the older and so I did."
وَقَالَ عَفَّانُ حَدَّثَنَا صَخْرُ بْنُ جُوَيْرِيَةَ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، أَنَّ النَّبِيَّ صلى الله عليه وسلم قَالَ " أَرَانِي أَتَسَوَّكُ بِسِوَاكٍ، فَجَاءَنِي رَجُلاَنِ أَحَدُهُمَا أَكْبَرُ مِنَ الآخَرِ، فَنَاوَلْتُ السِّوَاكَ الأَصْغَرَ مِنْهُمَا، فَقِيلَ لِي كَبِّرْ. فَدَفَعْتُهُ إِلَى الأَكْبَرِ مِنْهُمَا " . قَالَ أَبُو عَبْدِ اللَّهِ اخْتَصَرَهُ نُعَيْمٌ عَنِ ابْنِ الْمُبَارَكِ عَنْ أُسَامَةَ عَنْ نَافِعٍ عَنِ ابْنِ عُمَرَ.
