Why Does God Let Satan Exist?
Isaiah 14:12 How art thou fallen from heaven, O Lucifer, son of the morning! how art thou cut down to the ground, which didst weaken the nations!
13 For thou hast said in thine heart, I will ascend into heaven, I will exalt my throne above the stars of God: I will sit also upon the mount of the congregation, in the sides of the north:
14 I will ascend above the heights of the clouds; I will be like the most High.
15 Yet thou shalt be brought down to hell, to the sides of the pit. Isaiah 14:12-15
“And Satan will say when the matter has been concluded, "Indeed, Allah had promised you the promise of truth. And I promised you, but I betrayed you. But I had no authority over you except that I invited you, and you responded to me. So do not blame me; but blame yourselves. I cannot be called to your aid, nor can you be called to my aid. Indeed, I deny your association of me [with Allah] before. Indeed, for the wrongdoers is a painful punishment." Qur’an 14:22
“And [mention] when We said to the angels, "Prostrate to Adam," and they prostrated, except for Iblees. He said, "Should I prostrate to one You created from clay? [Iblees] said, "Do You see this one whom You have honored above me? If You delay me until the Day of Resurrection, I will surely destroy his descendants, except for a few. [Allah] said, "Go, for whoever of them follows you, indeed Hell will be the recompense of you - an ample recompense.” Qur’an 17:61-64
