مَا كَانَ لِلَّهِ أَن يَتَّخِذَ مِن وَلَدٍ ۖ سُبْحَـٰنَهُۥٓ ۚ إِذَا قَضَىٰٓ أَمْرًا فَإِنَّمَا يَقُولُ لَهُۥ كُن فَيَكُونُ
It is not [befitting] for Allah to take a son; exalted is He! When He decrees an affair, He only says to it, "Be," and it is.

وَٱلسَّلَـٰمُ عَلَىَّ يَوْمَ وُلِدتُّ وَيَوْمَ أَمُوتُ وَيَوْمَ أُبْعَثُ حَيًّا
And peace is on me the day I was born and the day I will die and the day I am raised alive."
ذَٰلِكَ عِيسَى ٱبْنُ مَرْيَمَ ۚ قَوْلَ ٱلْحَقِّ ٱلَّذِى فِيهِ يَمْتَرُونَ
That is Jesus, the son of Mary - the word of truth about which they are in dispute.
وَإِنَّ ٱللَّهَ رَبِّى وَرَبُّكُمْ فَٱعْبُدُوهُ ۚ هَـٰذَا صِرَٰطٌ مُّسْتَقِيمٌ
[Jesus said], "And indeed, Allah is my Lord and your Lord, so worship Him. That is a straight path."
فَٱخْتَلَفَ ٱلْأَحْزَابُ مِنۢ بَيْنِهِمْ ۖ فَوَيْلٌ لِّلَّذِينَ كَفَرُوا۟ مِن مَّشْهَدِ يَوْمٍ عَظِيمٍ
