لَقَدْ كَفَرَ الَّذِيْنَ قَالُوْٓا اِنَّ اللّٰهَ ثَالِثُ ثَلٰثَةٍۘ وَمَا مِنْ اِلٰهٍ اِلَّا͏ٓ اِلٰهٌ وَّاحِدٌؕ وَاِنْ لَّمْ يَنْتَهُوْا عَمَّا يَقُوْلُوْنَ لَيَمَسَّنَّ الَّذِيْنَ كَفَرُوْا مِنْهُمْ عَذَابٌ اَلِيْمٌ ٧٣
Translation
They are certainly faithless who say, ‘Allah is the third [person] of a trinity,’ while there is no god except the One God. If they do not relinquish what they say, there shall befall the faithless among them a painful punishment.
