Ibn Babawaih states in Thawab Al-A'amal Book: Shoeib Al-Orqubi reported from Imam Abou Abdellah (Pbuh) that he said: "He who recites Al-Teen Chapter in all his prayers shall be given what contents him of heaven."
Al-Tabarsi states in Majma' Al-Bayan Book: The Messenger of Allah (Pbuhp) said: "He who recites Al-Teen Chapter, Allah will grant him two traits: Health and Certainty as long as he lives in Donia. When he dies Allah will give him the reward of fasting one day for each time he read this chapter."
Khawas Al-Quran Book: The Messenger of Allah (Pbuhp) said: " He who recites Al-Teen Chapter, Allah will give him uncountable rewards as if he encountered Mohammad (Pbuhp) being saddened and he relieved him from his sadness. If it was recited on food, Allah removes all the harm that is in the food even if there was a deadly poison in it. It also gains curing activity."
