God doth wish to lighten your (difficulties). [Holy Quran: Nisaa 4:28]
Celibacy is a wound to morals and social purity. A celibate is the worst of people in site of the Almighty God in such a manner that it is frequently underlined in many Quranic verses and instructions of tradition. On the other hand, in Islam, the marriage is encouraged and apperciated and many blessings are put in it by the mercy of Allah. Considering the Islamic instructions Professor Hossein Ansaryan interprets this issue in his book “ The Islamic Family Structure”. The following text is an exemplar.
An Honorable Household
If a young adult or an adult man or woman does not marry, it seems to be rather impossible to remain chaste and free of corruption. It is a difficult problem to find a young adult out of millions, not married, yet be chaste and sinless. If we find a youth who is truly chaste and not married, then we may say she/he is one of God's Saints. Avoiding commitment of sins, remaining immune from corruption, being safe from the outburst of the instincts, and not being married at the same time is something only the Prophet Joseph could do.
A house in which an unmarried man and a woman live is not safe from corruption. If the man has no wife and the woman no husband, and their sexual instincts are alive with the pressure of lust, then those two have various mental, family and social problems and live in corruption. Marriage is a natural and divine law. It makes some problems easier to solve which are concerned with keeping the youth chaste and pious.
The establishment of a household in society must be founded on a healthy and peaceful basis. The couple live together by marrying and respecting each other's rights. Wherever a Muslim household is established it must be based on God's revelation and in the remembrance of Him day and night.
(Lit is such a Light) In houses, which God Hath permitted to be raised to honor; for the celebration, In them, of His name: in them is He glorified in the mornings and In the evenings, (again and again), [Holy Quran: Nur 24:36]
In such a house, with such attributes, one finds a household of believers in which worshipping God flourishes. God has ordered a marriage to take place there and the couple obeys all divine, humane laws. The Glorious Quran orders that marriage should take place so that a man and a woman's problems are solved through the realization of this tradition and they - being the future teachers of some children - will remain incorruptible.
A man and his wife establish a mutual life. Being in harmony with each other they make a home for God's remembrance. In such a house, the couple are real servants of God and their offspring are the fruits of virtue. Their behavior and morality are signs of divine etiquette and the traditions of the Prophets. When a believing couple get married, they both feel responsible to follow the divine laws. They find each other to be a helper to the other. They are two loving friends, two intimate companions, two sources of faith and two pillars of love and kindness. Thus they protect life from difficulties. If a difficulty should arise, they solve it easily and confront it with the arms of patience and fortitude.
The Worst People
Living in seclusion and not having a companion leads to many difficulties. It causes depression, despondency, nervous disorders and all types of mental and physical disorders. Being alone causes one to enter the world of imagination and vain thoughts and succumb to mental and moral illnesses. The Prophet (Pbuh) said:
Most of the People of the Fire on the Day of Judgment are those who refused to marry and start a family."[Marriage in Islam, p.26]
Also the Prophet (Pbuh) said:
The worst of your dead ones are the celibates. [Bihar al-Anwar, v.100, pp.220-221]
In another tradition he mentioned:
The most ignoble of your dead ones are the celibates. [Ibid]
In a wise speech he said:
The most Satanic ones amongst you are the celibates. Celibacy is the brother of Satan.[Ibid]
In some heavenly words he said:
The best of my nation are the married ones and the worst are the celibates.[Ibid]
The Prophet (Pbuh) also said:
If the dead celibates return to this world, they will surely marry. [Marriage in Islam, p.27]
And in another tradition the Prophet (Pbuh) said:
God curses the man who refuses to take a wife. [Ibid]
Why does the Noble Prophet of Islam interpret the celibates to be dwellers of the Fire, ignoble ones, brothers of Satan, the wicked, the seditious, and the cursed? This is because those who do not marry are forced into corruption, sedition, sin and make problems for their society and the family. In all aspects of life, they cause a lot of trouble.
According to the Quranic verses and Prophetic traditions, marriage endows humans with nobleness and respectfulness. Marriage keeps man safe from wickedness and God's punishment. It protects him from falling into the clutches of Satan. Marriage protects man from becoming a source of vice and corruption and he will be safe from God’s Wrath. All of this results in his comfort, peace and safety, righteousness and piety making life easier. This is why in the Holy Quran the lawful, Islamic marriage has been pointed out.
