True.

Explanation:

After Satan deceived Eve and Adam in eating the fruit of the forbidden tree, God gave out judgement on all three of them. He announced the futures of man (Adam), toiling for his need, suffering under the sun. Then, he cursed the serpent, saying in Genesis 3: 14 & 15

“Cursed are you above all livestock

   and all wild animals!

You will crawl on your belly

   and you will eat dust

   all the days of your life.

And I will put enmity

   between you and the woman,

   and between your offspring[a] and hers;

he will crush your head,

   and you will strike his heel.”

This is the immediate doom of Satan/ Lucifer/ the serpent.
