وَعَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «لَوْ يَعْلَمُ أَحَدُكُمْ مَا لَهُ فِي أَنْ يَمُرَّ بَيْنَ يَدَيْ أَخِيهِ مُعْتَرِضًا فِي الصَّلَاةِ كَانَ لَأَنْ يُقِيمَ مِائَةَ عَامٍ خَيْرٌ لَهُ مِنَ الْخُطْوَةِ الَّتِي خَطَا» . رَوَاهُ ابْنُ مَاجَهْ
