4:171
يَٰٓ أَهْلَ ٱلْ كِتَٰبِ لَا تَغْلُو ا۟ فِى دِينِ كُمْ وَ لَا تَقُولُ وا۟ عَلَى ٱللَّهِ إِلَّا ٱلْ حَقَّ إِنَّ مَا ٱلْ مَسِيحُ عِيسَى ٱبْنُ مَرْيَمَ رَسُولُ ٱللَّهِ وَ كَلِمَتُ هُۥٓ أَلْقَىٰ هَآ إِلَىٰ مَرْيَمَ وَ رُوحٌ مِّنْ هُ فَ ـَٔامِنُ وا۟ بِ ٱللَّهِ وَ رُسُلِ هِۦ وَ لَا تَقُولُ وا۟ ثَلَٰثَةٌ ٱنتَهُ وا۟ خَيْرًا لَّ كُمْ إِنَّ مَا ٱللَّهُ إِلَٰهٌ وَٰحِدٌ سُبْحَٰنَ هُۥٓ أَن يَكُونَ لَ هُۥ وَلَدٌ لَّ هُۥ مَا فِى ٱل سَّمَٰوَٰتِ وَ مَا فِى ٱلْ أَرْضِ وَ كَفَىٰ بِ ٱللَّهِ وَكِيلًا
O People of the Scripture, do not commit excess in your religion or say about Allah except the truth. The Messiah, Jesus, the son of Mary, was but a messenger of Allah and His word which He directed to Mary and a soul [created at a command] from Him. So believe in Allah and His messengers. And do not say, "Three"; desist - it is better for you. Indeed, Allah is but one God. Exalted is He above having a son. To Him belongs whatever is in the heavens and whatever is on the earth. And sufficient is Allah as Disposer of affairs.
5:77
قُلْ يَٰٓ أَهْلَ ٱلْ كِتَٰبِ لَا تَغْلُو ا۟ فِى دِينِ كُمْ غَيْرَ ٱلْ حَقِّ وَ لَا تَتَّبِعُ وٓا۟ أَهْوَآءَ قَوْمٍ قَدْ ضَلُّ وا۟ مِن قَبْلُ وَ أَضَلُّ وا۟ كَثِيرًا وَ ضَلُّ وا۟ عَن سَوَآءِ ٱل سَّبِيلِ
Say, "O People of the Scripture, do not exceed limits in your religion beyond the truth and do not follow the inclinations of a people who had gone astray before and misled many and have strayed from the soundness of the way."
