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. (Surah Al-Baqarah, 2:27)

يَصِلُونَ yaṣilūna · join

Except for those who take refuge with a people between yourselves and whom is a treaty or those who come to you, their hearts strained at [the prospect of] fighting you or fighting their own people. And if Allāh had willed, He could have given them power over you, and they would have fought you. So if they remove themselves from you and do not fight you and offer you peace, then Allāh has not made for you a cause [for fighting] against them. (Surah An-Nisa, 4:90)

مَا جَعَلَ اللَّهُ مِن بَحِيرَةٍ وَلَا سَائِبَةٍ وَلَا وَصِيلَةٍ وَلَا حَامٍ وَلَٰكِنَّ الَّذِينَ كَفَرُوا يَفْتَرُونَ عَلَى اللَّهِ الْكَذِبَ وَأَكْثَرُهُمْ لَا يَعْقِلُونَ ١٠٣

وَلَقَدْ وَصَّلْنَا لَهُمُ الْقَوْلَ لَعَلَّهُمْ يَتَذَكَّرُونَ ٥١

وَصَّلْنَا waṣṣalnā · We have conveyed
