Sayyiduna Aws bin Aws (may Allah be pleased with him) says that the Messenger of Allah (peace and blessings be upon him), mentioning Friday, said: "Whoever washes his limbs and then takes a bath, sets out early in the morning, sits close to the imam, stays silent and listens attentively, his sins until the next Friday and three more days besides will be forgiven; and whoever touches the pebbles has done something futile."
