The Worthless Deeds: Rejecting prophets renders all good works invalid.
The good deeds of those who reject the messengers become void in this world and the Hereafter, and they will have no helper. Ensure your foundation is sound. All acts of charity, kindness, or service are only validated by the foundation of sincere monotheism and acceptance of God's messengers. Good deeds built on disbelief will fail on the final Day.
