"And hold fast, together, by the Rope which Allah stretches out for you, and be not divided among yourselves. And remember with gratitude Allah's favor on you. For you were enemies, and He joined your hearts in love, so that by His Grace, you became brethren. And you were on the brink of the Pit of Fire, and He saved you from it. Thus does Allah make His Signs clear to you, that you may be guided." 3:103
