Sahih Muslim Book 4, Hadith Number 1868.

Chapter : Excellence of going out early on Friday.

Abu Huraira reported Allah’s Messenger (may peace be upon him) as saying: He who performed ablution well, then came to Friday prayer, listened (to the sermon), kept silence all (his sins) between that time and the next Friday would be forgiven with three days extra, and he who touched pebbles caused an interruption.
