Ibn Babawaih states in Thawab Al-A'amal Book: Imam Abou Jaa'far (Pbuh) said: "He who recites Sadd Chapter on a Friday eve shall be given good of Donia and Hereafter what was not given to anyone but messenger prophets or close angels. Allah will send him to heaven and the ones he loves from his household even his servant that used to serve him. (****)."
Al-Tabarsi states in Majma' Al-Bayan Book: The Messenger of Allah (Pbuhp) said: "He who recites Sadd chapter is given rewards or righteous deeds in the weight of every mountain that Allah subjected to Dawood and Allah will prevent him from being consistent on a sin either a small or a big sin."
