Don't worry, God does not hear the prayers of the wicked.
Proverbs 15:8 KJV
The sacrifice of the wicked is an abomination to the Lord : but the prayer of the upright is his delight.
Proverbs 15:29 KJV
The Lord is far from the wicked: but he heareth the prayer of the righteous.

I know God does not hear the prayers of the wicked. but their prayers are addressed to the enemy of God. as the book of Job confirms, God let them mess around for some time.
