Because of the aforementioned reasons, the thinkers of Islam have attributed great significance to family. Families are like the seeds of a society. As a matter of historical fact, families built on strong bases protect and embellish the structure of their society, while families established by spiritually unequal partners, destroy it.
The principles and measures of Islam work to establish a happy and balanced family. One might say that Islam aims at peace and tranquility through family. That is why it is said that “home is the Paradise of the living.” As a matter of fact, a home set up according to divine rules is like Paradise on earth.
Because such a noble ideal and institution can only be achieved through exalted measures and lawful foundations based on love, Islam begins this spiritual journey with mutual vows. Islamic law requires both parties to give certain promises to each other in the name of Allah the Almighty.
The old saying “marriage works miracles” points out the significance and benefits of the marriage agreement in establishing a peaceful family. The value of our acts depends on our intentions. The outcome of living as partners without being married, without an explicit exchange of vows expressing our intentions, is disappointment and collapse not only on the personal level but also at the level of society as a whole. That is why cohabitation without a marriage agreement is prohibited by Islam and accepted as one of the grave sins. There will be harsh divine punishment for such practices in the Hereafter.
