Ibn Babawaih states in Thawab Al-A'amal Book: Moawia bin Ammar reported from Imam Abou Abdellah (Pbuh) that he said: "He who recites Al-Shams, Al-Doha and Al-Inshirah Chapters frequently in a night or during a day, everything that was present with him will testify for him on Resurrection Day even his hair, skin, flesh, blood, veins, nerves and bones along with everything that the ground carried for him. Then Allah will say: "Your testimony for My servant is accepted. Take him to My heavens so that he chooses what he pleases and give it to him out of My mercy and virtue. Congratulations to my servant."
Al-Tabrasi states in Majma' Al-Bayan Book: The Messenger of Allah (Pbuhp) said: "He who recites Al-Doha Chapter shall be among the ones with whom Allah is content, Mohammad shall intercede for him and he will earn rewards of ten righteous deeds multiplied by the count of every orphan and beggar."
Khawas Al-Quran Book: The Messenger of Allah (Pbuhp) said: "He who recites Al-Doha Chapter earns the intercession of Mohammad (Pbuhp) on Resurrection Day. He earns rewards of ten righteous deeds multiplied by the count of every orphan and beggar. Writing it for a lost person brings him back safe to his companions. If one forgot a matter somewhere and then he remembered, if he recites this chapter Allah shall safeguard it till its owner comes and takes it."
