Unification

The believers are nothing else than brothers (in Islaamic religion). So make reconciliation between your brothers. Surah Hujarat [49:10]

But when you enter the houses, greet one another with a greeting from Allâh (i.e. say: As-Salâmu 'Alaikum - peace be on you) blessed and good. Thus Allâh makes clear the Ayât (these Verses or your religious symbols and signs, etc.) to you that you may understand. Surah Nur [24:61]

O you who believe! Let not a group scoff at another group, it may be that the latter are better than the former; nor let (some) women scoff at other women, it may be that the latter are better than the former, nor defame one another, nor insult one another by nicknames. How bad is it, to insult one's brother after having Faith [i.e. to call your Muslim brother (a faithful believer) as: "O sinner", or "O wicked", etc.]. And whosoever does not repent, then such are indeed Zâlimûn (wrong-doers, etc.). Surah Hujarat [49:11]

O you who believe! Eat not up your property among yourselves unjustly except it be a trade amongst you, by mutual consent. And do not kill yourselves (nor kill one another). Surely, Allâh is Most Merciful to you. Surah Nisaa [4:29]

And He has united their (i.e. believers) hearts. If you had spent all that is in the earth, you could not have united their hearts, but Allah has united them. Certainly He is All-Mighty, All-Wise. Surah Anfal [8:63]

O you who believe! Stand out firmly for Allah and be just witnesses and let not the enmity and hatred of others make you avoid justice. Be just: that is nearer to piety, and fear Allah. Verily, Allah is Well Acquainted with what you do. Surah Maeda [5:8]
