فَبِمَا نَقْضِهِم مِّيثَٰقَهُمْ لَعَنَّٰهُمْ وَجَعَلْنَا قُلُوبَهُمْ قَٰسِيَةًۭ ۖ يُحَرِّفُونَ ٱلْكَلِمَ عَن مَّوَاضِعِهِۦ ۙ وَنَسُوا۟ حَظًّۭا مِّمَّا ذُكِّرُوا۟ بِهِۦ ۚ وَلَا تَزَالُ تَطَّلِعُ عَلَىٰ خَآئِنَةٍۢ مِّنْهُمْ إِلَّا قَلِيلًۭا مِّنْهُمْ ۖ فَٱعْفُ عَنْهُمْ وَٱصْفَحْ ۚ إِنَّ ٱللَّهَ يُحِبُّ ٱلْمُحْسِنِينَ
And because of their breaking their covenant, We have cursed them and made hard their hearts. They change words from their context and forget a part of that whereof they were admonished. Thou wilt not cease to discover treachery from all save a few of them. But bear with them and pardon them. Lo! Allah loveth the kindly.
Surah Al-Maaida(5:13)
