لَّقَدۡ كَفَرَ ٱلَّذِينَ قَالُوٓاْ إِنَّ ٱللَّهَ ثَالِثُ ثَلَٰثَةٍ ۘ وَمَا مِنۡ إِلَٰهٍ إِلَّآ إِلَٰهٌ وَٰحِدٌ ۚ وَإِن لَّمۡ يَنتَهُواْ عَمَّا يَقُولُونَ لَيَمَسَّنَّ ٱلَّذِينَ كَفَرُواْ مِنۡهُمۡ عَذَابٌ أَلِيمٌ
They do blaspheme who say: Allah is one of three in a Trinity: for there is no god except One Allah. If they desist not from their word (of blasphemy), verily a grievous penalty will befall the blasphemers among them.<br/>
They are indeed disbelievers those who say, 'God is the third of three', gods, that is, He is one of them, the other two being Jesus and his mother, and they [who claim this] are a Christian sect; when there is no god but the One God. If they do not desist from what they say, when they declare a trinity, and profess His Oneness, those of them who disbelieve, that is, [those] who are fixed upon unbelief, shall suffer a painful chastisement, namely, the Hellfire.
