Qur'an 2:27 · Al-Baqara

ٱلَّذِينَ يَنقُضُونَ عَهْدَ ٱللَّهِ مِنۢ بَعْدِ مِيثَٰقِهِۦ وَيَقْطَعُونَ مَآ أَمَرَ ٱللَّهُ بِهِۦٓ أَن يُوصَلَ وَيُفْسِدُونَ فِى ٱلْأَرْضِ ۚ أُو۟لَٰٓئِكَ هُمُ ٱلْخَٰسِرُونَ

(27) Who break the covenant of Allāh after contracting it and sever that which Allāh has ordered to be joined and cause corruption on earth. It is those who are the losers.
