Is this magic, or do you not see?
Then is this magic, or do you not see?
(52:15) Is this, then, any feat of magic or are you unable to see? *10
*10) That is, "When the Messengers in the world warned you of this Hell. you said that it was only by magic that they were fooling you. Now say: Is this Hell which you are facing mere magic, or you still do not see that you have actually met with the same Hell which was being foretold to you?"
