Those who break Allah's Covenant after it is ratified, and who sunder what Allah Has ordered to be joined, and do mischief on earth: These cause loss (only) to themselves. Quran 2:27)

There are three statements:

1. Those, who break Allah’s Covenant after it is ratified. According to some chronically judeophobe commentators this sentence refers to the Covenant between Jews and God which was broken by Jews. If it was true, we should consider Quran as a tight history book and interpretations cannot exceed the relation between Children of Israel and God. However, we have already a Book like that. It is called Torah or Old Testament. No matter we accept it as genuine or not, we have to admit that Torah is the revelation what covers the relation between God and the Jews. Is Quran the same? It is quite different! If Quran is different the statement above has to be considered as parable and its meaning is general what covers the relation between MEN and GOD including us! So, my friend even you are not excluded at all! You cannot read Quran as an outsider. While reading it you are travelling with its internal meaning as if you were involved in a divine journey. Yes, God has a Covenant even with you! Since He blew soul in your body, He is with you and you are responsible for keeping this Covenant. You are debtor with your intentions, deeds, life and wealth for your Creator, because these are only deposits what don’t belong to you! Deposit is not your property so you have to treat it in a way that depositor would like it. Here you are the Covenant between you and your Creator!
2. Those, who sunder what Allah Has ordered to be joined. Everything is moving on an orbit. The movement or circulation takes place according to a divine law. Even physics knows laws like gravitation etc. You can refuse it or act against it, however, it is useless. Gravitation effects on a well calculated way on the earth. Everything follows laws like gravitation. The regulations are followed by the whole nature including men. Discovering the laws what are followed by objects is prescribed for us. Several ayas in Quran orders for us to watch and study carefully the Signs of the external world. Men is part of the creation so men cannot hide from the applications of the laws in the creation. Men cannot exclude themselves from creation and cannot behave like tyrant in the creation. They can do only one thing: to fit into creation. If they do differently, they may enjoy on short term the advantages however on long term they lose themselves. Same happens on the scale of society, too. Men can pass laws by their own or by their parliaments, they can put on the market foodstuff which are cheap but the ingredients contain hazardous materials, they can force interest rates, they can involve people’s money to prohibited speculations etc. but if these all go against the prescriptions of Allah it is only matter of time and everything will turn upside down. Free will and consciousness doesn’t mean advantage sometimes. If the motivation is based on weakness the free will and consciousness are disadvantages.
3. Those who do mischief on earth. There are creative and constructive characters and there are those who survive on the expense of others like parasites. They are those who show off from themselves different issues what they have. They look as if they were wise and give orders but they miss the wisdom. They look as if they were the embodiment of morality but they are fallible. They look as if they have content but they are empty. Without them the world can survive properly however they cannot survive without the world. They stick to what they hope to be profitable than suck, put in the pocket their booties without taking into consideration the consequences. In their arsenal we can find the Fitna (intrigue, temptation, perturbance), Hypocrisy and in their character dominates Baghi (greedy desire for acquiring), which are the main sins in Islam.

Many people fit the above “loser” definition, don’t they? So, calm down! The time will come for every loser!
