Surah Ar-Ra'd, ayah 25

وَٱلَّذِينَ يَنقُضُونَ عَهۡدَ ٱللَّهِ مِنۢ بَعۡدِ مِيثَٰقِهِۦ وَيَقۡطَعُونَ مَآ أَمَرَ ٱللَّهُ بِهِۦٓ أَن يُوصَلَ وَيُفۡسِدُونَ فِي ٱلۡأَرۡضِ أُوْلَٰٓئِكَ لَهُمُ ٱللَّعۡنَةُ وَلَهُمۡ سُوٓءُ ٱلدَّارِ ٢٥

Walladhīna yanqudūna 'ahdallāhi mim ba'di mīthāqihī wayaqta'ūna mā amarallāhu bihī an yūsala wayufsidūna fil-ardi ulā'ika lahumul-la'natu walahum sū'ud-dār

But those who break the covenant of Allāh after contracting it and sever that which Allāh has ordered to be joined and spread corruption on earth - for them is the curse, and they will have the worst home.⁶³⁹
