Quran 2, Al-Baqara (The Cow) ⓘ

2:89And when there cometh unto them a scripture from Allah, confirming that in their possession - though before that they were asking for a signal triumph over those who disbelieved - and when there cometh unto them that which they know (to be the truth) they disbelieve therein. The curse of Allah is on disbelievers.

وَلَمَّا جَاءَهُمْ كِتَابٌ مِنْ عِنْدِ اللَّهِ مُصَدِّقٌ لِمَا مَعَهُمْ وَكَانُوا مِنْ قَبْلُ يَسْتَفْتِحُونَ عَلَى الَّذِينَ كَفَرُوا فَلَمَّا جَاءَهُمْ مَا عَرَفُوا كَفَرُوا بِهِ فَلَعْنَةُ اللَّهِ عَلَى الْكَافِرِينَ

2:90Evil is that for which they sell their souls: that they should disbelieve in that which Allah hath revealed, grudging that Allah should reveal of His bounty unto whom He will of His slaves. They have incurred anger upon anger. For disbelievers is a shameful doom.

بِئْسَمَا اشْتَرَوْا بِهِ أَنْفُسَهُمْ أَنْ يَكْفُرُوا بِمَا أَنْزَلَ اللَّهُ بَغْيًا أَنْ يُنَزِّلَ اللَّهُ مِنْ فَضْلِهِ عَلَى مَنْ يَشَاءُ مِنْ عِبَادِهِ فَبَاءُوا بِغَضَبٍ عَلَى غَضَبٍ وَلِلْكَافِرِينَ عَذَابٌ مُهِينٌ

2:91And when it is said unto them: Believe in that which Allah hath revealed, they say: We believe in that which was revealed unto us. And they disbelieve in that which cometh after it, though it is the truth confirming that which they possess. Say (unto them, O Muhammad): Why then slew ye the prophets of Allah aforetime, if ye are (indeed) believers?

وَإِذَا قِيلَ لَهُمْ آمِنُوا بِمَا أَنْزَلَ اللَّهُ قَالُوا نُؤْمِنُ بِمَا أُنْزِلَ عَلَيْنَا وَيَكْفُرُونَ بِمَا وَرَاءَهُ وَهُوَ الْحَقُّ مُصَدِّقًا لِمَا مَعَهُمْ قُلْ فَلِمَ تَقْتُلُونَ أَنْبِيَاءَ اللَّهِ مِنْ قَبْلُ إِنْ كُنْتُمْ مُؤْمِنِينَ
