Tirmidhi Book 37, Hadith 2497

حَدَّثَنَا هَنَّادٌ، حَدَّثَنَا أَبُو مُعَاوِيَةَ، عَنِ الْأَعْمَشِ، عَنْ عُمَارَةَ بْنِ عُمَيْرٍ، عَنِ الْحَارِثِ بْنِ سُوَيْدٍ، حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مَسْعُودٍ بِحَدِيثَيْنِ:‏‏‏‏ أَحَدِهِمَا عَنْ نَفْسِهِ، ‏‏‏‏‏‏وَالْآخَرِ عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ، ‏‏‏‏‏‏قَالَ عَبْدُ اللَّهِ:‏‏‏‏ إِنَّ الْمُؤْمِنَ يَرَى ذُنُوبَهُ كَأَنَّهُ فِي أَصْلِ جَبَلٍ يَخَافُ أَنْ يَقَعَ عَلَيْهِ، ‏‏‏‏‏‏وَإِنَّ الْفَاجِرَ يَرَى ذُنُوبَهُ كَذُبَابٍ وَقَعَ عَلَى أَنْفِهِ ،‏‏‏‏ قَالَ بِهِ هَكَذَا فَطَارَ.

Al-Harith bin Suwaid said: 'Abdullah [bin Mas'ud] narrated two Ahadith to us, one of them from himself and the other from the Prophet (s.a.w). 'Abdullah said: 'The believer sees his sins as if he was at the base of a mountain, fearing that it was about to fall upon him. The wicked person sees his sins as if (they are) flies are hitting his nose he said: Like this - motioning with his hand - to get them to fly away.
