عَنْ سَعْدِ بْنِ أَبِي وَقَّاصٍ قَالَ: جَاءَ أَعْرَابِيٌّ إِلَى رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَقَالَ: عَلِّمْنِي كَلَامًا أَقُولُهُ قَالَ: «قُلْ لَا إِلَهَ إِلَّا اللَّهُ وَحْدَهُ لَا شَرِيكَ لَهُ اللَّهُ أَكْبَرُ كَبِيرًا وَالْحَمْدُ لِلَّهِ كَثِيرًا وَسُبْحَانَ اللَّهِ رَبِّ الْعَالَمِينَ لَا حَوْلَ وَلَا قُوَّةَ إِلَى بِاللَّهِ الْعَزِيزِ الْحَكِيمِ» . فَقَالَ فَهَؤُلَاءِ لِرَبِّي فَمَا لِي؟ فَقَالَ: «قُلِ اللَّهُمَّ اغْفِرْ لِي وَارْحَمْنِي وَاهْدِنِي وَارْزُقْنِي وَعَافِنِي» . شَكَّ الرَّاوِي فِي «عَافِنِي» . رَوَاهُ مُسلم

Anas said that, on coming upon a tree whose leaves were withered, God's messenger struck it with his staff, and the leaves were scattered. He then said that “Praise be to God; Glory be to God; There is no god but God; and God is most great” cause a man's sins to fall away just as the leaves of that tree were falling. Tirmidhi transmitted it, saying this is a gharib tradition.
