And take hold of God's rope all together and do not be divided. And remember God's favors upon you when you were enemies and he united your hearts so that you became by his grace, brothers.
"And hold fast, all of you together, the rope of Allah (i.e. the Qur'an), and do not be divided among yourselves, and remember Allah's favor upon you, for once you were enemies to one another, but He joined your hearts together, so that by His grace you became brothers" - Holy Qur'an 3:103.
