Also Allah Says:
"And this [Qur`an] is a blessed message which We have sent down. Then are you with it unacquainted?" [Al-Anbiya (21): 50]
"And whoever turns away from My remembrance - indeed, he will have a depressed life, and We will gather him on the Day of Resurrection blind. He will say, 'my Lord, why have You raised me blind while I was [once] seeing?' [Allah] will say, 'thus did Our signs come to you, and you forgot them; thus will you this Day be forgotten." [Ta Ha (20): 124-126]
