Quran 2:27 from Surah Al-Baqara on Divine Marvels.
ٱلَّذِينَ يَنقُضُونَ عَهۡدَ ٱللَّهِ مِنۢ بَعۡدِ مِيثَٰقِهِۦ وَيَقۡطَعُونَ مَآ أَمَرَ ٱللَّهُ بِهِۦٓ أَن يُوصَلَ وَيُفۡسِدُونَ فِي ٱلۡأَرۡضِۚ أُوْلَٰٓئِكَ هُمُ ٱلۡخَٰسِرُونَ
English translation: Those who break (the) Covenant (of) Allah from after its ratification and [they] cut what has ordered Allah it to be joined and [they] spread corruption in the earth Those they (are) the losers
Transliteration: alladhina yanquduna ahda al-lahi min ba'di mithaqihi wayaqta'una ma amara al-lahu bihi an yusala wayuf'siduna fi al-ardi ulaika humu al-khasiruna
