Surah Al-Imran, ayah 103

وَٱعۡتَصِمُواْ بِحَبۡلِ ٱللَّهِ جَمِيعٗا وَلَا تَفَرَّقُواْۚ وَٱذۡكُرُواْ نِعۡمَتَ ٱللَّهِ عَلَيۡكُمۡ إِذۡ كُنتُمۡ أَعۡدَآءٗ فَأَلَّفَ بَيۡنَ قُلُوبِكُمۡ فَأَصۡبَحۡتُم بِنِعۡمَتِهِۦٓ إِخۡوَٰنٗا وَكُنتُمۡ عَلَىٰ شَفَا حُفۡرَةٖ مِّنَ ٱلنَّارِ فَأَنقَذَكُم مِّنۡهَاۗ كَذَٰلِكَ يُبَيِّنُ ٱللَّهُ لَكُمۡ ءَايَٰتِهِۦ لَعَلَّكُمۡ تَهۡتَدُونَ ١٠٣

Wa'tasimū bihablillāhi jamī'an walā tafarraqū wadhkurū ni'matallāhi 'alaykum idh kuntum a'dā'an fa allafa bayna qulūbikum fa asbahtum bini'matihī ikhwānan wakuntum 'alā shafā hufratim minan-nāri fa anqadhakum minhā kadhālika yubayyinullāhu lakum āyātihī la'allakum tahtadūn

And hold firmly to the rope¹⁴² of Allāh all together and do not become divided. And remember the favor of Allāh 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 Allāh make clear to you His verses that you may be guided.
