Musannaf Ibn Abi Shaybah 43 — Keeping up ablution and its virtue

It is narrated from Sayyiduna Amr bin Abasah (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "When a man washes his hands while performing ablution, the sins that his hands committed are washed away; when he washes his face, the sins of his face are washed away; when he washes his forearms, the sins of his forearms are washed away; and when he washes his feet, all the sins committed by his feet are forgiven."
