They have certainly disbelieved who say, "Allāh is the Messiah, the son of Mary" while the Messiah has said, "O Children of Israel, worship Allāh, my Lord and your Lord." Indeed, he who associates others with Allāh - Allāh has forbidden him Paradise, and his refuge is the Fire. And there are not for the wrongdoers any helpers.
The Christians who say that ‘Allah is the Messiah, Jesus, son of Mary’ have committed disbelief, as they have attributed Lordship to someone other than Allah. The Messiah, Jesus, son of Mary, himself said to them, ‘O Israelites, worship Allah alone. He is my Lord and your Lord. We are all His servants’. Whoever ascribes anything as a partner to Allah, then Allah will not allow them to ever enter Paradise and their place will be the fire of Hell. They will have no one to help or assist them before Allah and no one to save them from the punishment that awaits them.
