I was with Salman Farsi beneath a tree. He took a dry branch from it and shook it until its leaves fell off. Then he said, "Abu Uthman, will you not ask me why I did this?"I said, "Why did you do it?"He said, "This is what the Messenger of Allah ﷺ did when I was with him beneath a tree. He took a dry branch from it and shook it until its leaves fell off, then he said, 'Salman, will you not ask me why I did this?'I said, 'Why did you do it?'He said, 'When a Muslim performs ablution well and then prays the five prayers, his sins fall away just as these leaves fall away.' Then he recited, "And establish prayer at the two ends of the day and at the approach of the night. Indeed, good deeds drive away bad deeds. That is a reminder for those who remember." [Hud 11:114]"
حدثنا عفان حدثنا حماد بن سلمة أخبرنا علي بن زيد
كنت مع سلمان الفارسي تحت شجرة وأخذ منها غصنا يابسا فهزه حتى تحات ورقه ثم قال يا أبا عثمان ألا تسألني لم أفعل هذا قلت ولم تفعله فقال هكذا فعل رسول الله ﷺ وأنا معه تحت شجرة فأخذ منها غصنا يابسا فهزه حتى تحات ورقه فقال يا سلمان ألا تسألني لم أفعل هذا فقلت ولم تفعله قال إن المسلم إذا توضأ فأحسن الوضوء ثم صلى الصلوات الخمس تحاتت خطاياه كما يتحات هذا الورق وقال {وأقم الصلاة طرفي النهار وزلفا من الليل إن الحسنات يذهبن السيئات ذلك ذكرى للذاكرين}
