Jami' bin Shaddad narrates: He heard Humran telling Abu Burdah this statement. Sayyiduna Uthman Ghani (may Allah be pleased with him) reported this saying of the Prophet Muhammad (peace and blessings be upon him): "Whoever performs ablution completely in the manner Allah has commanded, then the five prayers become an expiation for the sins committed between them."
