Wa'tasimoo bi Hablil laahi jamee'anw wa laa tafarraqoo; wazkuroo ni'matal laahi alaikum iz kuntum a'daaa'an fa allafa baina quloobikum fa asbah tum bini'matiheee ikhwaananw wa kuntum 'alaa shafaa hufratim minan Naari fa anqazakum minhaa; kazaalika yubaiyinul laahu lakum aayaatihee la'allakum tahtadoon (ʾĀl ʿImrān 3:103)
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 [3] : 103)
