مُحَمَّدُ بْنُ أَحْمَدَ عَنْ عَبْدِ اللَّهِ بْنِ الصَّلْتِ عَنْ يُونُسَ عَمَّنْ ذَكَرَهُ عَنْ أَبِي بَصِيرٍ قَالَ قَالَ أَبُو عَبْدِ اللَّهِ (عليه السلام) يَا أَبَا مُحَمَّدٍ إِنَّ لِلَّهِ عَزَّ وَ جَلَّ مَلَائِكَةً يُسْقِطُونَ الذُّنُوبَ عَنْ ظُهُورِ شِيعَتِنَا كَمَا تُسْقِطُ الرِّيحُ الْوَرَقَ مِنَ الشَّجَرِ فِي أَوَانِ سُقُوطِهِ وَ ذَلِكَ قَوْلُهُ عَزَّ وَ جَلَّ يُسَبِّحُونَ بِحَمْدِ رَبِّهِمْ... وَ يَسْتَغْفِرُونَ لِلَّذِينَ آمَنُوا وَ اللَّهِ مَا أَرَادَ بِهَذَا غَيْرَكُمْ.

Allah (azwj) Mighty and Majestic has Angels who cut off the sins from the backs of our  Shites just like the cutting by the wind of the leaves from the tree in the season of autumn and that is the Statement of the Mighty and Majestic: “[40:7] hymn the praises of their Lord and believe in Him and ask forgiveness for those who believe”, and Allah (azwj) has not Intended by this other than you’.
