لَقَدْ كَفَرَ الَّذِيْنَ قَالُوْٓا اِنَّ اللّٰهَ هُوَ الْمَسِيْحُ ابْنُ مَرْيَمَ ۗوَقَالَ الْمَسِيْحُ يٰبَنِيْٓ اِسْرَاۤءِيْلَ اعْبُدُوا اللّٰهَ رَبِّيْ وَرَبَّكُمْ ۗاِنَّهٗ مَنْ يُّشْرِكْ بِاللّٰهِ فَقَدْ حَرَّمَ اللّٰهُ عَلَيْهِ الْجَنَّةَ وَمَأْوٰىهُ النَّارُ ۗوَمَا لِلظّٰلِمِيْنَ مِنْ اَنْصَارٍ ( المائدة: ٧٢ )

They have certainly disbelieved who say, "Allah is the Messiah, the son of Mary" while the Messiah has said, "O Children of Israel, worship Allah, my Lord and your Lord." Indeed, he who associates others with Allah – Allah has forbidden him Paradise, and his refuge is the Fire. And there are not for the wrongdoers any helpers. (Al-Ma'idah  : 72)

Surely, disbelievers are those who say, “Allah is the MasīH, son of Maryam” while the MasīH had said, “O children of Isrā’īl , worship Allah, my Lord and your Lord.” In fact, whoever ascribes any partner to Allah, Allah has prohibited for him the Jannah (the Paradise), and his shelter is the Fire, and there will be no supporters for the unjust.
