Quran verses about Allah

يَٰٓأَهْلَ ٱلْكِتَٰبِ لَا تَغْلُوا۟ فِى دِينِكُمْ وَلَا تَقُولُوا۟ عَلَى ٱللَّهِ إِلَّا ٱلْحَقَّ إِنَّمَا ٱلْمَسِيحُ عِيسَى ٱبْنُ مَرْيَمَ رَسُولُ ٱللَّهِ وَكَلِمَتُهُۥٓ أَلْقَىٰهَآ إِلَىٰ مَرْيَمَ وَرُوحٌ مِّنْهُ فَـَٔامِنُوا۟ بِٱللَّهِ وَرُسُلِهِۦ وَلَا تَقُولُوا۟ ثَلَٰثَةٌ ٱنتَهُوا۟ خَيْرًا لَّكُمْ إِنَّمَا ٱللَّهُ إِلَٰهٌ وَٰحِدٌ سُبْحَٰنَهُۥٓ أَن يَكُونَ لَهُۥ وَلَدٌ لَّهُۥ مَا فِى ٱلسَّمَٰوَٰتِ وَمَا فِى ٱلْأَرْضِ وَكَفَىٰ بِٱللَّهِ وَكِيلًا ۝١٧١

O People of the Scripture, do not commit excess in your religion or say about Allāh except the truth. The Messiah, Jesus the son of Mary, was but a messenger of Allāh and His word which He directed to Mary and a soul [created at a command] from Him. So believe in Allāh and His messengers. And do not say, "Three"; desist - it is better for you. Indeed, Allāh 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 Allāh as Disposer of affairs.

لَّقَدْ كَفَرَ ٱلَّذِينَ قَالُوٓا۟ إِنَّ ٱللَّهَ ثَالِثُ ثَلَٰثَةٍ وَمَا مِنْ إِلَٰهٍ إِلَّآ إِلَٰهٌ وَٰحِدٌ وَإِن لَّمْ يَنتَهُوا۟ عَمَّا يَقُولُونَ لَيَمَسَّنَّ ٱلَّذِينَ كَفَرُوا۟ مِنْهُمْ عَذَابٌ أَلِيمٌ ۝٧٣

They have certainly disbelieved who say, "Allāh is the third of three." And there is no god except one God. And if they do not desist from what they are saying, there will surely afflict the disbelievers among them a painful punishment.

وَقَالَ ٱللَّهُ لَا تَتَّخِذُوٓا۟ إِلَٰهَيْنِ ٱثْنَيْنِ إِنَّمَا هُوَ إِلَٰهٌ وَٰحِدٌ فَإِيَّٰىَ فَٱرْهَبُونِ ۝٥١

And Allāh has said, "Do not take for yourselves two deities. He [i.e., Allāh] is but one God, so fear only Me."
