5:12
۞ وَلَقَدْ أَخَذَ ٱللَّهُ مِيثَـٰقَ بَنِىٓ إِسْرَٰٓءِيلَ وَبَعَثْنَا مِنْهُمُ ٱثْنَىْ عَشَرَ نَقِيبًا ۖ وَقَالَ ٱللَّهُ إِنِّى مَعَكُمْ ۖ لَئِنْ أَقَمْتُمُ ٱلصَّلَوٰةَ وَءَاتَيْتُمُ ٱلزَّكَوٰةَ وَءَامَنتُم بِرُسُلِى وَعَزَّرْتُمُوهُمْ وَأَقْرَضْتُمُ ٱللَّهَ قَرْضًا حَسَنًا لَّأُكَفِّرَنَّ عَنكُمْ سَيِّـَٔاتِكُمْ وَلَأُدْخِلَنَّكُمْ جَنَّـٰتٍ تَجْرِى مِن تَحْتِهَا ٱلْأَنْهَـٰرُ ۚ فَمَن كَفَرَ بَعْدَ ذَٰلِكَ مِنكُمْ فَقَدْ ضَلَّ سَوَآءَ ٱلسَّبِيلِ
And Allah had already taken a covenant from the Children of Israel, and We delegated from among them twelve leaders. And Allah said, "I am with you. If you establish prayer and give zakah and believe in My messengers and support them and loan Allah a goodly loan, I will surely remove from you your misdeeds and admit you to gardens beneath which rivers flow. But whoever of you disbelieves after that has certainly strayed from the soundness of the way."

وَٱلَّذِينَ كَفَرُوا۟ وَكَذَّبُوا۟ بِـَٔايَـٰتِنَآ أُو۟لَـٰٓئِكَ أَصْحَـٰبُ ٱلْجَحِيمِ
But those who disbelieve and deny Our signs - those are the companions of Hellfire.
يَـٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوا۟ ٱذْكُرُوا۟ نِعْمَتَ ٱللَّهِ عَلَيْكُمْ إِذْ هَمَّ قَوْمٌ أَن يَبْسُطُوٓا۟ إِلَيْكُمْ أَيْدِيَهُمْ فَكَفَّ أَيْدِيَهُمْ عَنكُمْ ۖ وَٱتَّقُوا۟ ٱللَّهَ ۚ وَعَلَى ٱللَّهِ فَلْيَتَوَكَّلِ ٱلْمُؤْمِنُونَ
O you who have believed, remember the favor of Allah upon you when a people determined to extend their hands [in aggression] against you, but He withheld their hands from you; and fear Allah. And upon Allah let the believers rely.
فَبِمَا نَقْضِهِم مِّيثَـٰقَهُمْ لَعَنَّـٰهُمْ وَجَعَلْنَا قُلُوبَهُمْ قَـٰسِيَةً ۖ يُحَرِّفُونَ ٱلْكَلِمَ عَن مَّوَاضِعِهِۦ ۙ وَنَسُوا۟ حَظًّا مِّمَّا ذُكِّرُوا۟ بِهِۦ ۚ وَلَا تَزَالُ تَطَّلِعُ عَلَىٰ خَآئِنَةٍ مِّنْهُمْ إِلَّا قَلِيلًا مِّنْهُمْ ۖ فَٱعْفُ عَنْهُمْ وَٱصْفَحْ ۚ إِنَّ ٱللَّهَ يُحِبُّ ٱلْمُحْسِنِينَ
So for their breaking of the covenant We cursed them and made their hearts hard. They distort words from their [proper] usages and have forgotten a portion of that of which they were reminded. And you will still observe deceit among them, except a few of them. But pardon them and overlook [their misdeeds]. Indeed, Allah loves the doers of good.
وَمِنَ ٱلَّذِينَ قَالُوٓا۟ إِنَّا نَصَـٰرَىٰٓ أَخَذْنَا مِيثَـٰقَهُمْ فَنَسُوا۟ حَظًّا مِّمَّا ذُكِّرُوا۟ بِهِۦ فَأَغْرَيْنَا بَيْنَهُمُ ٱلْعَدَاوَةَ وَٱلْبَغْضَآءَ إِلَىٰ يَوْمِ ٱلْقِيَـٰمَةِ ۚ وَسَوْفَ يُنَبِّئُهُمُ ٱللَّهُ بِمَا كَانُوا۟ يَصْنَعُونَ
And from those who say, "We are Christians" We took their covenant; but they forgot a portion of that of which they were reminded. So We caused among them animosity and hatred until the Day of Resurrection. And Allah is going to inform them about what they used to do.
