This sūrah is named al-Nūr, meaning The Light, and light is identified as an essential attribute of God: “God is the light of the heavens and the earth.” (Verse 35) It is also mentioned in respect of its effects on people’s hearts and souls. Such effects are reflected in human morality and the manners of individuals, families and communities. They impart a brightness to human life that enlightens hearts and makes consciences transparent.

The sūrah begins with an emphatic declaration of the fact that it is bestowed from on high, and that it is decreed with all that it contains of directives, commandments and morality: “A sūrah which We have bestowed from on high and which We have ordained; and in it have We revealed clear verses, so that you may keep them in mind.” (Verse 1) This opening reflects the importance the Qur’ān attaches to the moral aspect of human life, and to its central position in the Islamic faith.

The central theme of the entire sūrah is the education of the Muslim community.

At times, the methods employed by the sūrah increase in their stiffness so as to culminate in prescribing mandatory punishments. At other times the sūrah is softer and more gentle, filling our hearts with God’s light and inviting us to reflect on the numerous signs He has placed throughout the entire universe. The aim of such contrasting approaches is one and the same: to cultivate people’s consciences, enhance their sensitivity and refine their moral standards to the highest degree. The good manners of the individual, the family, the community and society’s leadership are all intertwined as they all stem from the same source, which is belief in God, and shine with the same light received from Him. In essence, these manners combine light, transparency and brightness. Thus the education the sūrah aims to achieve derives all its aspects from the basic source of light in the heavens and earth; that is, God’s light that dispels all darkness in the universe, as well as that in people’s hearts and souls.

The sūrah may be divided into five parts, all tackling its basic theme. At the outset, the first delivers a decisive declaration outlining the status of this sūrah, followed by the details of the mandatory punishment for adultery. It denounces this crime in clear terms, making it clear that adulterers have no place in the Muslim community.

It also explains the punishment for any false accusation of adultery, and the reasons for the severity of this mandatory punishment. Couples are exempted from this punishment when they take the prescribed oaths that end with their permanent separation. It then comments on the falsehood story. At the end it shows how men and women flock like with like: the good with the good and the evil with the evil.

The second part concerns itself with crime prevention, and the methods to reduce the temptation to sin. It begins with an outline of good manners when approaching others’ homes and the need to seek permission before entry. It commands Muslims to lower their gaze and not to reveal women’s charms and adornments to anyone other than their very close relatives whom they are not legally entitled to marry. There is also in this part a clear encouragement to facilitate the marriage of young women, and a stern warning against forcing slave girls into prostitution. All these are preventive measures that aim to promote purity and chastity in general. They aim to prevent what stirs up physical desire and to help people to maintain their chastity.

In the middle of this list of good manners as outlined in the sūrah, the third part provides a link between all such manners and God’s light. Here the sūrah speaks of the people whose hearts are brightened with God’s light and who always frequent mosques. By contrast, the unbelievers and their deeds are shown as though they are a mirage, or like layers of darkness. In this part we see different aspects of God’s light throughout the universe: how all creatures glorify Him; how clouds are sent through the atmosphere; the succession of day and night; the creation of every walking creature out of water and how they acquire their different shapes, forms, types and roles. All these are there for people to look at and contemplate.

In the fourth part the hypocrites are seen to neglect the proper manners people should show when dealing with the Prophet. The most important of these are obedience to the Prophet and the implementation of any judgement he makes in disputes put to him for arbitration. By contrast, the believers are seen to maintain the appropriate standards in speaking to the Prophet and obeying him. In return, they are promised power, that they will establish and implement their faith and attain victory over the unbelievers.

The final part of the sūrah again examines the good manners of the Muslim community, highlighting the need to seek admission when visiting relatives and friends, of hospitality to guests, and the fine manners that make the whole Muslim community a single family, led by God’s Messenger (peace be upon him).

The sūrah concludes with a declaration of God’s ownership of all that is in the heavens and earth, His knowledge of people and what they harbour in their breasts, and their ultimate return to Him. They will have to face His reckoning on the basis of His knowledge of their deeds. Needless to say, His knowledge encompasses everything.
