Ibn Babawaih states in Thawab Al-A'amal Book: Abou Baseer reported from Imam Abou Abdellah (Pbuh) that he said: "He who recites Al-Feel Chapter in his regular prayers shall have every mountain, hill and valley witnessing that he was among the praying ones. One will call him on Resurrection Day: "You were honest about My servant. Your testimony is accepted. Escort him to heaven and don’t judge him. He is among the ones whom I love and love their conduct."
NB: Al-Sheikh Al-Sadouq said: "You should read Quraish Chapter with Al-Feel Chapter in the same prayer because they are considered to be a single chapter. Thus you can't recite one of them alone in a Rakaa' of a prayer."
Al-Tabarsi states in Majma' Al-Bayan Book: The Messenger of Allah (Pbuhp) said: "He who recites Al-Feel Chapter, Allah shall protect him from deformation and slander."
Khawas Al-Quran Book: The Messenger of Allah (Pbuhp) said: "He who recites Al-Feel Chapter Allah saves him from torment and deformation in Donia. Reciting it on arrows allows them to break whatever they hit."
