It is narrated from Hazrat Abu Dharr (may Allah be pleased with him) that once the Noble Prophet (peace and blessings be upon him) went out during the winter season, and at that time the leaves were falling. The Noble Prophet (peace and blessings be upon him) held two branches of a tree, and its leaves began to fall. The Noble Prophet (peace and blessings be upon him) said, "O Abu Dharr!" I replied, "Labbaik, O Messenger of Allah." He said, "When a Muslim servant offers prayer seeking the pleasure of Allah, his sins fall away just as the leaves of this tree are falling."
