It is narrated from Sayyiduna Abu Umamah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Whenever a Muslim performs ablution and completes his ablution on its proper places, his sins come out from his ears, his eyes, his body and his feet, and his prayer becomes a fadl (an extra good deed) for him."
