Sayyiduna Abu Hurayrah and Sayyiduna Abu Sa'id (may Allah be pleased with them both) say that they heard the Messenger of Allah (peace and blessings be upon him); he (peace and blessings be upon him) said: "Whoever takes a bath on Friday, uses the siwak, applies perfume if he has any, then puts on his finest clothes and comes to the mosque, does not step over people's necks, prays as much as Allah wills, and then remains silent from when his imam comes out until the end of the prayer, his sins from the previous Friday up to this Friday are forgiven." And Sayyiduna Abu Hurayrah (may Allah be pleased with him) says: "Three more days as well, because Allah Almighty rewards one good deed tenfold."
