Ibn Babawaih states in Thawab Al-A'amal Book: Abou Baseer reported from Imam Abou Abdellah (Pbuh) that he said: "He who recites Mohammad Chapter shall never have doubts about his religion. Allah shall never afflict him with poverty or fear from men in power. He will stay protected from doubt and disbelief till he dies. When he dies, Allah orders one thousand angels to pray in his grave and he gets the rewards of their prayers. They will follow him till they reach the safety level when he is safe by Allah and Mohammad (Pbuhp)."

Khawas Al-Quran Book: The Messenger of Allah (Pbuhp) said: "He who recites Mohammad Chapter shall see the face of the Messenger of Allah (Pbuhp) wherever he directs his sight when he exists his grave. Allah will indeed water him from the rivers of heaven. Writing it and attaching it to one saves him in his sleep and when awake from every threat by its blessings."
