Islam has established the interrelationships of the people of the society on two bases. One is the relationship of mutual brotherhood. This relationship serves as a very strong and unbreakable bond between different people. And the second is the protection of rights and dignity. The security and dignity of every person's blood, dignity and wealth. In the eyes of Islam, it is haraam to use words or behaviors that harm or damage these two foundations. Whether the loss is material or cultural, there is no difference. No matter how much it may be, it will be haraam in that sense. The following verses mention those haraam things which are detrimental to mutual brotherhood and human dignity.
Believers are brothers. So make peace between your brothers. O you who believe! No man would mock other men, because they could be better than him! You shall not afflict one another, neither shall you call one another bad. Fascism is the name of the inferior stage after accepting faith. And those who do not repent, they are the wrongdoers.
O you who believe! Stay away from many kinds of baseless ideas. Some baseless ideas are a clear sin, and you should not look for the faults of the people, lest anyone should spread his faults in the absence of others. You hate it. And fear God. Surely, Allah is Most Acceptor of Repentance, Most Merciful.
In the first verse, God says that believers are brothers. In it, along with human brotherhood, religious brotherhood is also present. The two are united and cohesive together. The claim of this brotherhood is that they will not be unrelated or unfamiliar to each other. Deep solidarity with each other is highly recommended. Not separated from each other, will be closely together. There will be no enmity, no animosity, no genuine love, no compassion. There will be no conflicts and differences of opinion, they will work in complete agreement. It has been said in Hadith.
You will not be jealous of each other, no one will fall behind anyone - no one will turn away from anyone. Do not indulge in mutual anger and resentment, but remain mutual servants and brothers of God.
