Ibn Babawaih states in Thawab Al-A'amal Book: Yazeed bin Khalifa reported from Imam Abou Abdellah (Pbuh) that he said: "He who constantly recites Al-Najem Chapter everyday or every night shall live praised and loved among people and he shall be forgive."
Al-Tabrasi states Majma' Al-Bayan Book: The Messenger of Allah (Pbuhp) said: "He who recites Al-Najem shall be rewards with ten righteous deeds multiplied by the count of who believed in Mohammad (Pbuhp) and who disbelieved in him."
Khawas Al-Quran Book: Imam Sadiq (Pbuh) said: "He who writes it on tiger skin and attaches it to himself, shall gain power over everything and every Sultan he goes to will respect him. He defeats everyone who fights him and he gains the power and the way by the leave of Allah."
