Ibn Babawaih states in Thawab Al-A'amal Book: Al-Hussein bin Abi Al-Alaa' reported from Imam Abou Abdellah (Pbuh) that he said: "He who recites constantly Al-Hadeed and Al-Mujadila Chapters in a regular prayer, Allah will not torment him ever until he dies. He shall never see any misfortune or evil affecting him or his family or any malfunction in his body."
It is also stated in Foqoh Al-Rida (Pbuh) Book.
Al-Tabarsi states in Majma' Al-Bayan Book: The Messenger of Allah (Pbuhp) said: "He who recites Al-Mujadila Chapter shall be among the party of Allah on Resurrection Day."
Khawas Al-Quran Book: The Messenger of Allah (Pbuhp) said: "He who recites Al-Mujadila Chapter shall be among the succeeding party of Allah on Resurrection Day. Writing it and attaching it to a patient relieves him from his pain. Reciting it over what is to be buried or stored protects it till its owner extracts it."
Khawas Al-Quran Book: The Messenger of Allah (Pbuhp) said: "Writing it and attaching it to a patient relieves him from his pain. Reciting it over what is to be buried or stored protects it till its owner extracts it."
Khawas Al-Quran Book: Imam Sadiq (Pbuh): "Reciting it for a patient relieves him pain and makes him sleep. Reciting it constantly each day or each night saves from Tariqs (Demons). Reciting it over what is to be buried or stored protects it till its owner extracts it. Writing it and placing it among seeds clears away everything that would spoil them."
