الماۤئدة — Al-Ma'idah Ayat 73
لَقَدْ كَفَرَ الَّذِيْنَ قَالُوْٓا اِنَّ اللّٰهَ ثَالِثُ ثَلٰثَةٍ ۘ وَمَا مِنْ اِلٰهٍ اِلَّآ اِلٰهٌ وَّاحِدٌ ۗوَاِنْ لَّمْ يَنْتَهُوْا عَمَّا يَقُوْلُوْنَ لَيَمَسَّنَّ الَّذِيْنَ كَفَرُوْا مِنْهُمْ عَذَابٌ اَلِيْمٌ
Laqad kafaral-lażīna qālū innallāha ṡāliṡu ṡalāsah(tin), wa mā min ilāhin illā ilāhuw wāḥid(un), wa illam yantahū ‘ammā yaqūlūna layamassannal-lażīna kafarū minhum ‘ażābun alīm(un).
"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."
