ٱلَّذِينَ يَنقُضُونَ عَهۡدَ ٱللَّهِ مِنۢ بَعۡدِ مِيثَٰقِهِۦ وَيَقۡطَعُونَ مَآ أَمَرَ ٱللَّهُ بِهِۦٓ أَن يُوصَلَ وَيُفۡسِدُونَ فِي ٱلۡأَرۡضِۚ أُوْلَٰٓئِكَ هُمُ ٱلۡخَٰسِرُونَ ٢٧
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.
Translation: Saheeh International (English)
Each word's meaning and sound
Those who break the promise they made with God to serve Him alone and follow His way. This is in the verse, “He made them testify concerning themselves: “Am I not your Lord?” They said, “Yes, we bear witness!” (7:172) He affirmed this by sending the prophets and the scriptures. Those who do not take their promises with God seriously are those who cut off from things which God instructed not to, such as blood relations and they work to spread corruption on earth through their wrongdoing. They are the losers in this world and the next.
