Ibn Babawaih states in Thawab Al-A'amal Book: Abou Hamza Al-Thamaly reported from Imam Ali Bin Al-Hussein (Pbuh) that he said: "He who recites Al-Mumtahana Chapter in all his prayers, Allah tests his heart for faith, enlighten his sight and shall never be poor, insane or his children."
Al-Tabarsi states in Majma' Al-Bayan Book: The Messenger of Allah (Pbuhp) said: "He who recites Al-Mumtahana Chapter shall have all the believers as his interceders on Resurrection Day."
Khawas Al-Quran Book: The Messenger of Allah (Pbuhp) said: " He who recites this Chapter, angels will send their prayers upon him and ask forgiveness for him. If he died in that night he dies as a martyr and the believers will intercede for him on Resurrection Day."
Khawas Al-Quran Book: Imam Sadiq (Pbuh) said: "He who has a disease in his spleen and isn’t cured must write it and drink it for three consecutive days. He will be cured by the leave of Allah."
