Quran Al-Baqarah 2:27
ٱلَّذِينَ يَنقُضُونَ عَهۡدَ ٱللَّهِ مِنۢ بَعۡدِ مِيثَٰقِهِۦ وَيَقۡطَعُونَ مَآ أَمَرَ ٱللَّهُ بِهِۦٓ أَن يُوصَلَ وَيُفۡسِدُونَ فِي ٱلۡأَرۡضِۚ أُوْلَٰٓئِكَ هُمُ ٱلۡخَٰسِرُونَ ٢٧
Translation
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.
