Unity of All Submitters

[3:200] O you who believe, you shall be steadfast, you shall persevere, you shall be united, you shall observe GOD, that you may succeed.

Unity of All Submitters

[2:62 and 5:69] Surely, those who believe, those who are Jewish, the Christians, and the converts; anyone who 
(1) believes in GOD, and 
(2) believes in the Last Day, and 
(3) leads a righteous life, 
will receive their recompense from their Lord. They have nothing to fear, nor will they grieve.

Believers are United

[3:103] You shall hold fast to the rope of GOD, all of you, and do not be divided. Recall GOD’s blessings upon you – you used to be enemies and He reconciled your hearts. By His grace, you became brethren. You were at the brink of a pit of fire, and He saved you therefrom. GOD thus explains His revelations for you, that you may be guided.

[3:104] Let there be a community of you who invite to what is good, advocate righteousness, and forbid evil. These are the winners.

[3:105] Do not be like those who became divided and disputed, despite the clear proofs that were given to them. For these have incurred a terrible retribution. 

Mark 3:24-25
24. If a kingdom is divided against itself, that kingdom cannot stand.
25. If a house is divided against itself, that house cannot stand.
