Abu Hurayrah (may Allah be pleased with him) says that the Messenger of Allah (peace and blessings be upon him) said: "Whoever takes a bath on Friday, uses the tooth-stick (miswak), wears good clothes and applies some of his family's perfume, then comes to the mosque without stepping over the necks of the people, and prays, and when the imam comes out he stays silent, this will be an expiation for the interval between the two Fridays."
