وَاعْتَصِمُوْا بِحَبْلِ اللّٰهِ جَمِيْعًا وَّلَا تَفَرَّقُوْا ۖوَاذْكُرُوْا نِعْمَتَ اللّٰهِ عَلَيْكُمْ اِذْ كُنْتُمْ اَعْدَاۤءً فَاَلَّفَ بَيْنَ قُلُوْبِكُمْ فَاَصْبَحْتُمْ بِنِعْمَتِهٖٓ اِخْوَانًاۚ وَكُنْتُمْ عَلٰى شَفَا حُفْرَةٍ مِّنَ النَّارِ فَاَنْقَذَكُمْ مِّنْهَا ۗ كَذٰلِكَ يُبَيِّنُ اللّٰهُ لَكُمْ اٰيٰتِهٖ لَعَلَّكُمْ تَهْتَدُوْنَ ( آل عمران: ١٠٣ )

And hold firmly to the rope of Allah all together and do not become divided. And remember the favor of Allah upon you – when you were enemies and He brought your hearts together and you became, by His favor, brothers. And you were on the edge of a pit of the Fire, and He saved you from it. Thus does Allah make clear to you His verses that you may be guided. (Ali 'Imran  : 103)

Hold fast, all of you, to the cord of Allah, and be not divided. Remember the blessing of Allah upon you: When you were enemies to each other, and He brought your hearts together, so that, you became brothers through His blessing. You were at the brink of a pit of Fire, then He saved you from it. This is how Allah makes His signs clear to you, so that you may take the right path.
