It is narrated from Abu Uthman that I was with Sayyiduna Salman al-Farsi (may Allah be pleased with him) under a tree when he broke off a dry branch and shook it, causing all its leaves to fall. He said: "Will you not ask me why I did this?" I replied: "Why did you do this?" He said: "The Messenger of Allah (peace and blessings be upon him) did the same when I was with him." Then the Prophet (peace and blessings be upon him) said: "When a Muslim performs ablution well and offers the five prayers, his sins fall away just like these leaves." Then he recited this noble verse: «﴿وَأَقِمِ الصَّلَاةَ طَرَفَيِ النَّهَارِ وَزُلَفًا مِنَ اللَّيْلِ﴾ إِلىٰ قَوْلِهٖ ﴿ذَلِكَ ذِكْرَى لِلذَّاكِرِينَ﴾» [هود 114/11 ] "Establish prayer at the two ends of the day and in some hours of the night. Indeed, good deeds remove bad deeds. That is a reminder for those who remember."
