وَمِنَ ٱلَّذِينَ قَالُوٓا۟ إِنَّا نَصَٰرَىٰٓ أَخَذْنَا مِيثَٰقَهُمْ فَنَسُوا۟ حَظًّۭا مِّمَّا ذُكِّرُوا۟ بِهِۦ فَأَغْرَيْنَا بَيْنَهُمُ ٱلْعَدَاوَةَ وَٱلْبَغْضَآءَ إِلَىٰ يَوْمِ ٱلْقِيَٰمَةِ ۚ وَسَوْفَ يُنَبِّئُهُمُ ٱللَّهُ بِمَا كَانُوا۟ يَصْنَعُونَ
And with those who say: "Lo! we are Christians," We made a covenant, but they forgot a part of that whereof they were admonished. Therefor We have stirred up enmity and hatred among them till the Day of Resurrection, when Allah will inform them of their handiwork.

Invocations
Chapter: To invoke Allah against Al-Mushrikun
Narrated Anas:
The Prophet (ﷺ) sent a Sariya (an army detachment) consisting of men called Al-Qurra', and all of them were martyred. I had never seen the Prophet (ﷺ) so sad over anything as he was over them. So he said Qunut (invocation in the prayer) for one month in the Fajr prayer, invoking for Allah's wrath upon the tribe of 'Usaiya, and he used to say, "The people of 'Usaiya have disobeyed Allah and His Apostle."
