سورة المائدة

لَقَدْ كَفَرَ الَّذِينَ قَالُوا إِنَّ اللَّهَ ثَالِثُ ثَلَاثَةٍ ۘ وَمَا مِنْ إِلَٰهٍ إِلَّا إِلَٰهٌ وَاحِدٌ ۚ وَإِنْ لَمْ يَنْتَهُوا عَمَّا يَقُولُونَ لَيَمَسَّنَّ الَّذِينَ كَفَرُوا مِنْهُمْ عَذَابٌ أَلِيمٌ ﴿٧٣﴾

Surah al-Ma'idah

73. They disbelieve those who say, “Allah is the third in a Trinity.” But there is no god, except One God. If they do not refrain from what they say, a painful punishment will befall those among them who disbelieve.
