Development of Islamic law
By Syed Imad-ud-Din Asad
ISLAMIC Law is the body of rules of conduct, revealed by God to his Prophet (peace be upon him), according to which the people are directed to lead their lives. Thus, unlike the western systems of law, the laws of Islam originate from revelation.
Revelation consists of:
1. The communications made by Gabriel, under the directions of God, to the Prophet, either in the very words of God or by hints;
2. Such knowledge as occurred in the mind of the Prophet through the inspiration from God; and
3. The opinion of the Prophet, embodied in the form of ratio-cination, delivered from time to time on the questions that happened to be raised before him.
The question may arise as to why the opinion of the Prophet is a part of revelation? Well, it is so because God has said: “Your companion (the Prophet) errs not, nor does he deviate, nor does he speak out of desire. It is naught but revelation that is revealed. One Mighty in Power has taught him, the Lord of strength. So he attained perfection.” (The Quran: Al-Najam; 2-6).
Revelation is available to us in the form of the Quran and the Traditions of the Prophet. The Quran comprises only those revelations which are made in the very words of God, while the rest form the corpus of the Traditions.
The rules of conduct provided by revelation comprise:
1. Laws which regulate men’s relations to and dealings among one another;
2. Laws which are concerned only with the spiritual aspect of individual life; and
3. Laws which not only concern the spiritual aspect of individual life, but also affect the Muslim society.
Another distinctive feature of the Islamic Law is that it attributes the authority of making laws to God only. According to the laws of Islam, no man or body of men can ever be capable of or allowed to make laws for other men. Now the big question arises that as the last set of laws made by God was bestowed upon mankind centuries ago, and as much has changed in the world since then, so in the absence of new laws for the new circumstances, how Islam managed to survive? In other words, as new laws cannot be made by men and as God has also not given any further laws, how can Islam cope and deal with the modern issues? It is an established fact that a legal system has to continuously adapt according to the needs of the changing time, otherwise, it loses its applicability and gradually fades away.
To begin with, as the laws available in the form of revelation are concerned, in them God has explained the fundamental principles of behaviour pertaining to all the essential human transactions, dealings, and matters.
He says: “...I have perfected for you your religion and completed My favour to you...” (The Quran: Al-Maidah 3) “...and We have revealed the Book to thee explaining all things...” (The Quran: Al-Nahl; 89) “And certainly We have set forth for men in this Quran similitudes of every sort that they may mind.” (The Quran: Al-Zumar; 27) “...If you quarrel about any thing, refer it to Allah (i.e., the Quran) and the Messenger (i.e., the Traditions), if you believe in Allah and the last day...” (The Quran: Al-Nisa; 59)
The verses tell us: 1. Revelation is a complete set of guiding principles; and 2. Revelation is well capable of settling and dealing with all controversies, conflicts, and problems.
However, where there is no room for the making of new laws, there is also no prohibition on the innovation, extension, and re-interpretation of the existing laws. This very process, which is highly encouraged by God and His Messenger, of innovation, extension, and re-interpretation of laws given in the Quran and the traditions, in order to explain and analyse the legality of the latest issues, is denoted by Ijtehad.
It is the method of Ijtehad by which God has enabled the Muslim jurists to: 1. Make provisions for the developing circumstances; and 2. Prove Islam as a system of life practical for all times. When Ijtehad is conducted by a single jurist, it is called Qiyas; and when it is conducted by a body of jurists, it is named Ijma.
If a Qiyas and an Ijma, both conducted at the same time regarding the same thing, come into conflict with each other, then Ijma is preferred over Qiyas. This is done due to the presumption that the jurists acting in a body are less likely to err than a jurist acting alone.
Let us see some examples of how the law is innovated and developed by way of Ijtehad. The Quran (Al-Maidah; 90, 91) has forbidden the drinking of alcohol. The ban has been put due to its being an intoxicant. By using Ijtehad this ban on the non-medical use of alcohol is applied to the use of all substances which have the property of intoxication. Heroin, which is a recent discovery, is also prohibited due to the same reason.
The Quran enjoins honouring of contracts and honesty in trade. These centuries-old commandments are also applicable to the present-day on-line contracts and e-business.
Similarly, whether a person steals money by using the conventional methods, or by drawing cash on a stolen credit card, or by transferring sums to his account by manipulating the computer system of a bank, he will remain a thief and will be dealt with in accordance with the laws given in the Quran and the Traditions.
The law developed by way of Ijtehad may or may not be good for all times. The whole universe is in transition; consequently, a rule which is suitable for a certain matter under certain circumstances may not be so if the facts governing the matter undergo a change.
This gives rise to the necessity for a continuous exercise of Ijtehad. To put it differently, whereas the law given in the form of revelation cannot be altered, amended, or annulled by the Muslim jurists, the law obtained by practising Ijtehad can be modified, replaced, or cancelled according to the demands of the latest facts.
