Qur'aanic Verse 82:19:
19. Yawma la tamliku nafsun linafsin shay-an waal-amru yawma-ithin lillahi
19. That Day no creature shall be of any avail to another. And Allah’s shall be the sole command that Day!2
2. Christians, who are sure their Christ [peace on him] will take them to Paradise, beware! And Muslims, who claim that whatever their deeds here in this world their Muhammad [peace on him] will ensure their entry into Jannah, beware!
