الترمذي:٣٧٩ – حَدَّثَنَا سَعِيدُ بْنُ عَبْدِ الرَّحْمَنِ الْمَخْزُومِيُّ حَدَّثَنَا سُفْيَانُ بْنُ عُيَيْنَةَ عَنِ الزُّهْرِيِّ عَنْ أَبِي الأَحْوَصِ عَنْ أَبِي ذَرٍّ

عَنِ النَّبِيِّ ﷺ قَالَ إِذَا قَامَ أَحَدُكُمْ إِلَى الصَّلاَةِ فَلاَ يَمْسَحِ الْحَصَى فَإِنَّ الرَّحْمَةَ تُوَاجِهُهُ قَالَ وَفِي الْبَابِ عَنْ مُعَيْقِيبٍ وَعَلِيِّ بْنِ أَبِي طَالِبٍ وَحُذَيْفَةَ وَجَابِرِ بْنِ عَبْدِ اللَّهِ  

قَالَ أَبُو عِيسَى حَدِيثُ أَبِي ذَرٍّ حَدِيثٌ حَسَنٌ وَقَدْ رُوِيَ عَنِ النَّبِيِّ ﷺ أَنَّهُ كَرِهَ الْمَسْحَ فِي الصَّلاَةِ وَقَالَ إِنْ كُنْتَ لاَ بُدَّ فَاعِلاً فَمَرَّةً وَاحِدَةً كَأَنَّهُ رُوِيَ عَنْهُ رُخْصَةٌ فِي الْمَرَّةِ الْوَاحِدَةِ وَالْعَمَلُ عَلَى هَذَا عِنْدَ أَهْلِ الْعِلْمِ
