It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "When a person performs ablution well, then sets out towards the mosque and nothing brings him out except the prayer, then (as long as he keeps walking) with every step of his left foot a sin is erased and with every step of his right foot a good deed is written, until he enters the mosque."
