Allah said,

﴿إِذْ قَالَ اللَّهُ يعِيسَى إِنِّي مُتَوَفِّيكَ وَرَافِعُكَ إِلَىَّ وَمُطَهِّرُكَ مِنَ الَّذِينَ كَفَرُواْ وَجَاعِلُ الَّذِينَ اتَّبَعُوكَ فَوْقَ الَّذِينَ كَفَرُواْ إِلَى يَوْمِ الْقِيَـمَةِ ثُمَّ إِلَيَّ مَرْجِعُكُمْ فَأَحْكُمُ بَيْنَكُمْ فِيمَا كُنتُمْ فِيهِ تَخْتَلِفُونَ - فَأَمَّا الَّذِينَ كَفَرُواْ فَأُعَذِّبُهُمْ عَذَاباً شَدِيداً فِي الدُّنْيَا وَالاٌّخِرَةِ وَمَا لَهُمْ مِّن نَّـصِرِينَ ﴾

(And I will make those who follow you superior to those who disbelieve till the Day of Resurrection. Then you will return to Me and I will judge between you in the matters in which you used to dispute. As to those who disbelieve, I will punish them with a severe torment in this world and in the Hereafter, and they will have no helpers.)

This is what Allah did to the Jews who disbelieved in `Isa and the Christians who went to the extreme over him. Allah tormented them in this life; they were killed, captured, and lost their wealth and kingdoms. Their torment in the Hereafter is even worse and more severe,

﴿وَمَا لَهُم مِّنَ اللَّهِ مِن وَاقٍ﴾

(And they have no Waq (defender or protector) against Allah) ﴿13:34﴾.

﴿وَأَمَّا الَّذِينَ ءَامَنُوا وَعَمِلُواْ الصَّـلِحَاتِ فَيُوَفِّيهِمْ أُجُورَهُمْ﴾

(And as for those who believe and do righteous good deeds, Allah will pay them their reward in full) in this life, with victory and domination, and in the Hereafter, with Paradise and high grades,

﴿وَاللَّهُ لاَ يُحِبُّ الظَّـلِمِينَ﴾

(And Allah does not like the wrongdoers.)

Allah then said,

﴿ذَلِكَ نَتْلُوهُ عَلَيْكَ مِنَ الآيَـتِ وَالذِّكْرِ الْحَكِيمِ ﴾

(This is what We recite to you of the verses and the Wise Reminder.) meaning, "What We narrated to you, O Muhammd, regarding `Isa, his birth and his life, is what Allah conveyed and revealed to you, sent down from the Al-Lawh Al-Mahfuz (The Preserved Tablet). So there is no doubt in it. Similarly, Allah said in Surah Maryam;

﴿ذلِكَ عِيسَى ابْنُ مَرْيَمَ قَوْلَ الْحَقِّ الَّذِى فِيهِ يَمْتُرُونَ - مَا كَانَ للَّهِ أَن يَتَّخِذَ مِن وَلَدٍ سُبْحَـنَهُ إِذَا قَضَى أَمْراً فَإِنَّمَا يَقُولُ لَهُ كُن فَيَكُونُ ﴾

(Such is `Isa, son of Maryam. (It is) a statement of truth, about which they doubt (or dispute). It befits not Allah that He should beget a son. Glorified be He. When He decrees a thing, He only says to it: "Be!'' and it is.)

﴿إِنَّ مَثَلَ عِيسَى عِندَ اللَّهِ كَمَثَلِ ءَادَمَ خَلَقَهُ مِن تُرَابٍ ثُمَّ قَالَ لَهُ كُن فَيَكُونُ - الْحَقُّ مِن رَّبِّكَ فَلاَ تَكُنْ مِّن الْمُمْتَرِينَ - فَمَنْ حَآجَّكَ فِيهِ مِن بَعْدِ مَا جَآءَكَ مِنَ الْعِلْمِ فَقُلْ تَعَالَوْاْ نَدْعُ أَبْنَآءَنَا وَأَبْنَآءَكُمْ وَنِسَآءَنَا وَنِسَآءَكُمْ وَأَنفُسَنَا وأَنفُسَكُمْ ثُمَّ نَبْتَهِلْ فَنَجْعَل لَّعْنَتُ اللَّهِ عَلَى الْكَـذِبِينَ - إِنَّ هَـذَا لَهُوَ الْقَصَصُ الْحَقُّ وَمَا مِنْ إِلَـهٍ إِلاَّ اللَّهُ وَإِنَّ اللَّهَ لَهُوَ الْعَزِيزُ الْحَكِيمُ - فَإِن تَوَلَّوْاْ فَإِنَّ اللَّهَ عَلِيمٌ بِالْمُفْسِدِينَ ﴾

(59. Verily, the likeness of `Isa before Allah is the likeness of Adam. He created him from dust, then said to him: "Be!'' and he was.) (60. (This is) the truth from your Lord, so be not of those who doubt.) (61. Then whoever disputes with you concerning him after the knowledge that has come to you, say: "Come, let us call our sons and your sons, our women and your women, ourselves and yourselves, then we pray and we invoke Allah's curse upon the liars.'') (62. Verily, this is the true narrative, and there is no god except Allah. And indeed, Allah is the Almighty, the All-Wise.) (63. And if they turn away, then surely, Allah is All-Aware of those who do mischief.)
