Anas bin Malik narrated that:

the Prophet ﷺ passed by a tree with dry leaves, so he struck it with his staff, making the leaves fall. Then he said: “Indeed, all praise is due to Allah, (Al-Hamdulillah)’ ‘glory to Allah, (Subhan Allah)’ none has the right to be worshipped by Allah, (La Ilaha Illallah)’ and ‘Allah is the greatest (Allahu Akbar)’ cause the sins to fall from the worshipper, just as the leaves of this tree fall.”

حَدَّثَنَا مُحَمَّدُ بْنُ حُمَيْدٍ الرَّازِيُّ، حَدَّثَنَا الْفَضْلُ بْنُ مُوسَى، عَنِ الأَعْمَشِ، عَنْ أَنَسٍ، أَنَّ رَسُولَ اللَّهِ ﷺ مَرَّ بِشَجَرَةٍ يَابِسَةِ الْوَرَقِ فَضَرَبَهَا بِعَصَاهُ فَتَنَاثَرَ الْوَرَقُ فَقَالَ " إِنَّ الْحَمْدَ لِلَّهِ وَسُبْحَانَ اللَّهِ وَلاَ إِلَهَ إِلاَّ اللَّهُ وَاللَّهُ أَكْبَرُ لَتُسَاقِطُ مِنْ ذُنُوبِ الْعَبْدِ كَمَا تَسَاقَطَ وَرَقُ هَذِهِ الشَّجَرَةِ " . قَالَ هَذَا حَدِيثٌ غَرِيبٌ . وَلاَ نَعْرِفُ لِلأَعْمَشِ سَمَاعًا مِنْ أَنَسٍ إِلاَّ أَنَّهُ قَدْ رَآهُ وَنَظَرَ إِلَيْهِ .
