The unity of Muslims

And hold firmly to the rope[1] 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.

1- Referring either to His covenant or the Quraan.
