Khawas Al-Quran Book: The Messenger of Allah (Pbuhp) said: "He who recites this chapter, is given rewards of ten righteous deeds multiplied by the count of who believed in Mohammad (Pbuhp) in Makka and who disbelieved in him. He who recites it constantly and asks Allah to memorize Quran afterwards, shall never die until Allah opens his heart and makes him memorize it."
