Musnad Ahmad 962:130

Abu al-Nadr narrated to us, Abd al-Hamid ibn Bahram narrated to us, from Shahr ibn Hawshab, Abu Umamah narrated to me, that the Messenger of Allah (peace and blessings of Allah be upon him) said: "Any man who stands for his ablution, intending to pray, then washes his palms, his sin falls from his palms with the first drop. When he rinses his mouth, sniffs water into his nose, and blows it out, his sin falls from his tongue and his lips with the first drop. When he washes his face, his sin falls from his hearing and his sight with the first drop. When he washes his hands up to the elbows and his feet up to the ankles, he is safe from every sin that belongs to him and from every fault, like his state on the day his mother gave birth to him." He said: "And when he stands for prayer, Allah raises his degree by it, and if he sits, he sits safe."
