Sayyiduna Abu Sa'id al-Khudri (may Allah be pleased with him) reports that the Prophet (peace and blessings be upon him) said: "Whoever attends the Friday prayer, does not engage in idle talk in it, does not behave ignorantly, performs ablution well and attends it with the imam, it will be an expiation for (his sins) between that Friday and the Friday after it. And whoever offers an obligatory prayer, it becomes an expiation for (the sins) between that prayer and the prayer after it."
Al-Tabarani recorded it in al-Mu'jam al-Awsat; its chain contains Dawud bin Abd al-Hamid, who is da'if (weak).
