The Table Spread - 5:72
"Those who say: "Allah is the Messiah, son of Mary,"have certainly disbelieved. But the Messiah said, "Children of Israel, serve Allah, my Lord and your Lord. Whoever associates partners with Allah, Allah forbids him Paradise, and his abode will be the Fire. And there will be no helper for the wrongdoers."
The wrongdoing of those who associate partners with Allah is on their own souls because their deeds are canceled:
Luqman/31:13
"When Lokman advised his son, he said: "My dear son, do not associate partners with Allah; surely shirk (associating partners with God) is a great wrong."
The Companies/39:65
It has been revealed to you and those before you that if you associate partners, all that you do will be in vain and you will be of the losers.
The Cattle/6:82
Those who believe and do not mix their faith with wrongdoing, they deserve security and they have found the truth.
