Quran 3, Ali 'Imran (House of Imran) ⓘ

3:103And hold fast, all of you together, to the cable of Allah, and do not separate. And remember Allah's favour unto you: How ye were enemies and He made friendship between your hearts so that ye became as brothers by His grace; and (how) ye were upon the brink of an abyss of fire, and He did save you from it. Thus Allah maketh clear His revelations unto you, that haply ye may be guided,

وَاعْتَصِمُوا بِحَبْلِ اللَّهِ جَمِيعًا وَلَا تَفَرَّقُوا وَاذْكُرُوا نِعْمَتَ اللَّهِ عَلَيْكُمْ إِذْ كُنْتُمْ أَعْدَاءً فَأَلَّفَ بَيْنَ قُلُوبِكُمْ فَأَصْبَحْتُمْ بِنِعْمَتِهِ إِخْوَانًا وَكُنْتُمْ عَلَى شَفَا حُفْرَةٍ مِنَ النَّارِ فَأَنْقَذَكُمْ مِنْهَا كَذَلِكَ يُبَيِّنُ اللَّهُ لَكُمْ آيَاتِهِ لَعَلَّكُمْ تَهْتَدُونَ
