Many people, Muslim and non-Muslim, have often asked me, “Why are there so many rules in Islam?” Of course, my answer is, “There aren’t.” But what would satisfy the soul of someone seeking such mysteries is to know the philosophy or purpose behind the shari’ah. According to the ‘aqidah (formula of beliefs) of some schools of al-Islam, every injunction, recommendation, and prohibition in the shari’ah has a purpose behind it and is based upon either benefit or harm.
Accordingly, when something new is brought before a mujtahid, smoking for example, its benefit or harm plays a large role in determining whether it is obligatory (wajib), recommended (mustahhab), permissible (mubah), disliked (makruh), or forbidden (haram).
To continue with the example of smoking, many scholars of the past labeled it makruh (disliked) because of its offensive odor, but left open a clause that, if it was discovered to be harmful to the body, it would then become haram. In modern times, advancements in science have revealed that smoking is harmful (and in many cases deadly) for the body, for people exposed to second-hand smoke, and to the environment. As a result, some modern scholars, such as Ayatullah al-’Udhma Nasir Makarem Shirazi, have labeled it haram, and in his case, have actually initiated youth programs and public service campaigns to encourage people to stop smoking.
When it comes to other issues, such as the prohibition of alcohol, the recommendation to wash your hands before you eat, the recommendation for marriage, and the plethora of various laws and ethics that al-Islam lays out for humanity, it is to our benefit to study their purposes. It increases one’s iman (faith) and enables us to explore and appreciate the love that Allah has for His servants.
None of our worship is of any benefit to Allah. We do not, in any way, increase His power, wealth, or health by serving Him. On the contrary, what He has revealed, which is sound and complete, is entirely for our benefit, both in this life and in the hereafter.
Nevertheless, seeking out the understanding of shari’ah does not remove responsibility from a Muslim and allow him to follow his own desires because he perceives some benefit to doing so. We must still arrive at rulings through the correct sources of legislation and formulate just and correct verdicts through reasoning (‘aql). If one is knowledgeable of these sources and capable of deducing rulings through reasoning, such a person might be qualified as a mujtahid (jurist). Because most of us do not even come close to the level of ijtihad necessary, we must rely on the juristic decisions of someone more knowledgeable and wise. The practice of this reliance is referred to as Taqlid.
Some “reformists” have mistakenly referred to this practice as “blind imitation” or even, insultingly, as “aping.” Yet, if they were suffering from a medical ailment, they would seek out medical advice and treatment from a medical professional. They would not rely on their own desires for a cure or consider mere conjecture to be medicine.
Similarly, if someone is interested in learning a particular field of studies, he should seek out that knowledge from qualified institutions that employ reputable teachers capable of relating the inner dimensions of a subject to him. If I was interested in physics, I would not seek knowledge of it from a nutritionist. It would be illogical, and in some cases, it could be harmful to me.
When a Muslim needs juristic advice or treatment for a disease of the soul, he must turn to the experts, those whose hearts are purified and whose knowledge is sufficient to address all or some of a person’s concerns. Taqlid is particularly applied in the field of jurisprudence (fiqh, but other areas, such as ‘irfan (gnosis), require experts who are aware of the inner mysteries and dimensions of their specialty.
