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
Those people who say that God is the third of three are defying [the truth]: there is only One God. If they persist in what they are saying, a painful punishment will afflict those of them who persist.
أَفَلَا يَتُوبُونَ إِلَى ٱللَّهِ وَيَسۡتَغۡفِرُونَهُۥۚ وَٱللَّهُ غَفُورٞ رَّحِيمٞ
Why do they not turn to God and ask His forgiveness, when God is most forgiving, most merciful?
مَّا ٱلۡمَسِيحُ ٱبۡنُ مَرۡيَمَ إِلَّا رَسُولٞ قَدۡ خَلَتۡ مِن قَبۡلِهِ ٱلرُّسُلُ وَأُمُّهُۥ صِدِّيقَةٞۖ كَانَا يَأۡكُلَانِ ٱلطَّعَامَۗ ٱنظُرۡ كَيۡفَ نُبَيِّنُ لَهُمُ ٱلۡأٓيَٰتِ ثُمَّ ٱنظُرۡ أَنَّىٰ يُؤۡفَكُونَ
The Messiah, son of Mary, was only a messenger; other messengers had come and gone before him; his mother was a virtuous woman; both ate food [like other mortals]. See how clear We make these signs for them; see how deluded they are.
قُلۡ أَتَعۡبُدُونَ مِن دُونِ ٱللَّهِ مَا لَا يَمۡلِكُ لَكُمۡ ضَرّٗا وَلَا نَفۡعٗاۚ وَٱللَّهُ هُوَ ٱلسَّمِيعُ ٱلۡعَلِيمُ
Say, ‘How can you worship something other than God, that has no power to do you harm or good? God alone is the All Hearing and All Knowing.’
