It is narrated from Sayyiduna Abu Umamah (may Allah be pleased with him), in a report traced back to the Prophet, that the Prophet (peace and blessings be upon him) said: "Any Muslim who performs ablution, washes his hands, rinses his mouth, and performs ablution as he has been commanded, Allah forgives him on that day the sins that came from his tongue, that his hand touched, and that he walked towards, until the sins fall away from the edges of his limbs. Then when he walks to the mosque, a good deed is written for one step, and a bad deed is erased with the other."
