Al Maidah, 73 Ayah
5:73
لَّقَدۡ كَفَرَ ٱلَّذِينَ قَالُوٓاْ إِنَّ ٱللَّهَ ثَالِثُ ثَلَٰثَةٖۘ وَمَا مِنۡ إِلَٰهٍ إِلَّآ إِلَٰهٞ وَٰحِدٞۚ وَإِن لَّمۡ يَنتَهُواْ عَمَّا يَقُولُونَ لَيَمَسَّنَّ ٱلَّذِينَ كَفَرُواْ مِنۡهُمۡ عَذَابٌ أَلِيمٌ ٧٣
Laqad Kafara Al-Ladhīna Qālū 'Inna Al-Laha Thālithu Thalāthatin ۘ Wa Mā Min 'Ilahin 'Illā 'Ilahun Wāĥidun ۚ Wa 'In Lam Yantahū `Ammā Yaqūlūna Layamassanna Al-Ladhīna Kafarū Minhum `Adhābun 'Alīmun
They have certainly disbelieved who say, " Allah 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.
