الترمذي:٧٢٥ – حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ مَهْدِيٍّ حَدَّثَنَا سُفْيَانُ عَنْ عَاصِمِ بْنِ عُبَيْدِ اللَّهِ عَنْ عَبْدِ اللَّهِ بْنِ عَامِرِ بْنِ رَبِيعَةَ عَنْ أَبِيهِ قَالَ

رَأَيْتُ النَّبِيَّ ﷺ مَا لاَ أُحْصِي يَتَسَوَّكُ وَهُوَ صَائِمٌ قَالَ وَفِي الْبَابِ عَنْ عَائِشَةَ  

قَالَ أَبُو عِيسَى حَدِيثُ عَامِرِ بْنِ رَبِيعَةَ حَدِيثٌ حَسَنٌ وَالْعَمَلُ عَلَى هَذَا عِنْدَ أَهْلِ الْعِلْمِ لاَ يَرَوْنَ بِالسِّوَاكِ لِلصَّائِمِ بَأْسًا إِلاَّ أَنَّ بَعْضَ أَهْلِ الْعِلْمِ كَرِهُوا السِّوَاكَ لِلصَّائِمِ بِالْعُودِ الرَّطْبِ وَكَرِهُوا لَهُ السِّوَاكَ آخِرَ النَّهَارِ وَلَمْ يَرَ الشَّافِعِيُّ بِالسِّوَاكِ بَأْسًا أَوَّلَ النَّهَارِ وَلاَ آخِرَهُ وَكَرِهَ أَحْمَدُ وَإِسْحَاقُ السِّوَاكَ آخِرَ النَّهَارِ
