good tidings to My servants who give ear to the word and follow the fairest of it. Those are they whom Allah has guided; those are men possessed of minds. (39:17)
To summarize, it may be said that the only approach to Islam is by accepting its tenets in such a way as one is entirely convinced of their validity, and this can only come about if one examines them carefully and conscientiously. Once one has come to accept these tenets it follows as a necessary consequence that one must adhere to the shari'ah, either by following a mujtahid in taqlid, or by undertaking the acquisition of learning and piety to such a degree that one becomes a mujtahid oneself.
3. Taqlid in the Qur'an and ahadith
The Qur'an instructs Muslims to seek guidance from people of learning in matters about which they lack knowledge:
"Question the people of remembrance if you do not know." (21:7)
It is an obligation in Islamic law to study everything which is necessary for the spiritual and material development and well-being of an Islamic community, but it is an obligation which is known as wajib kifa'i.* In the present instance, for example, an Islamic society has need of experts in the medical sciences, in physics and chemistry, engineering, education, and so forth, and as long as there is a lack of knowledge in these areas it is an obligation on the community as a whole to acquire it, which means that a group of Muslims should devote themselves to research so as to benefit the Islamic people as a whole.
Similarly, an Islamic society without experts in the shari'ah cannot properly consider itself Islamic, so it is an obligation for a group of persons from this society to devote themselves to the study of the religious sciences, so as to provide divine guidance for all Muslims. This is the meaning contained in the verse of the Qur'an which states:
"But why should not a party from every section of them (the believers) go forth to become learned in the religion, and to warn their people when they return to them, that they may beware?" (9:124)
It is clear that the Imams used to be pleased if any of their companions taught religion or gave legal rulings (fatwa) to others. There are a number of documented cases of Shi'ahs who lived far from Medina asking the Imam of the time to appoint someone in their locality to adjudicate between them in religious problems. Zakariyyah ibn Adam al-Qummi and Yunus bin `Abdu? r-Rahman, for example, were named by Imam `Ali ar-Rida' to solve disputes in their own districts.2
In a famous hadith, `Umar ibn Hanzalah asked Imam Ja`far as-Sadiq, peace be upon him, about the legality of two Shi'ahs seeking a verdict from an illegitimate ruler in a dispute over a debt or a legacy. The Imam's answer was that it was absolutely forbidden to do so. Then Ibn Hanzalah asked what the two should do, and the Imam replied: "They must seek out one of you who narrates our traditions, who is versed in what is permissible and what is forbidden, who is well-acquainted with our laws and ordinances, and accept him as judge and arbiter, for I appoint him as judge over you. If the ruling which he based on our laws is rejected, this rejection will be tantamount to ignoring the order of Allah and rejecting us is the same as rejecting Allah, and this is the same as polytheism."3
In another tradition from Imam Ja'far as-Sadiq, this time narrated by Imam Hasan al-`Askari, peace be upon them, he says, "...but if there is anyone among the fuqaha' who is in control over his own self, protects his religion, suppresses his evil desires and is obedient to the commands of his Master, then the people should follow him."4
A third hadith is from the Present Imam, Muhammad al-Mahdi, peace be upon him, who said in a reply to Ishaq ibn Ya'qub: "As far as newly occurring circumstances are concerned, you should turn (for guidance) to the narrators of our ahadith, for they are my proof over you just as I am Allah's proof."5 We can understand two things from these verses of the Qur'an and the ahadith of the Imams: 1) there must always be a group of fuqaha' in every Muslim society; 2) those who are not qualified as fuqaha' or mujtahids, must follow one, and that to go against his instruction in religious matters is tantamount to polytheism.
4. The necessary conditions for qualification as a mujtahid
It can easily be inferred from the second of the ahadith cited above that becoming an expert in fiqh and the other Islamic sciences is not in itself enough for qualification as a mujtahid whom everyone can follow. In addition to this, Islamic law lays down that a mujtahid should be a free man of legitimate birth who is past the age of puberty, sane, an Ithna-`ashari Shi'ah, and `adil, (which can be translated as 'just', but which includes other moral and legal qualities, such as piety and abstention from all that the shari`ah forbids and fulfillment of all its obligations).
As to the question of how an ordinary believer should discover who is the mujtahid he must follow, there are three recognized ways: 1) by his own personal knowledge if he is himself a religious scholar; 2) by the testimony of two `adil, knowledgeable persons to someone's being a mujtahid; 3) by a degree of popularity which leaves no doubt as to a person's being a mujtahid.
Most present day `ulama' maintain that it is most desirable to follow a mujtahid who is al-a`lam. In a general sense this means 'the most learned', but in this specific contexts it means the faqih who has the greatest expertise in deriving the rulings of the shari`ah from the sources. The a`lam may be recognized in any of the three ways a mujtahid can.6 However, it is sometimes difficult for the Shi'ah `ulama' to distinguish whom among all the fuqaha' is the most learned, and, as a result, more than one mujtahid may be followed in taqlid at one time (though not, of course, by the same person), as is the case at present, but any such multiplicity does not result in any practical disagreement on legal matters within the Shi'ah community.
5. Why are there differences among the mujtahids in their legal opinions?
Many people wonder why it is that the mujtahids differ in their religious opinions, or fatwas, when the bases of their ijtihad are the same. Firstly, it should be said that any differences in the fatwas is hardly ever such as to be contradictory; it is almost impossible to find a case of one mujtahid saying some action is wajib and another saying it is haram.
Take, for instance, the case of salatu 'l-jum`ah, the Friday prayer. All the Shi'ah `ulama' are of the opinion that in the time of the presence of the Imam this salat is obligatory on Fridays, because it is the Imam, or his representative, who has the right to call the people to Friday prayer; but they differ as to what is the correct course of action when the Imam is in Occultation.
This difference of opinion does not, however, create any practical problem for the community. The late Ayatullah as-Sayyid Muhsin al-Hakim (d. 1970) was one of the opinion that salatu 'l-jum`ah is not obligatory during the Occultation of the Imam, but it does not matter if someone performs it supposing that it is expected (of him), provided that he also prays the noon prayer (salatu 'z-zuhr).
Ayatullah as-Sayyid Abu 'l-Qasim al-Khu'i says that "one can choose between performing salatu 'z-zuhr or salatu 'l-jum`ah, but once the latter is established with all its conditions (fulfilled), it is precautionarily obligatory to participate in it." Ayatullah as-Sayyid Ruhullah al-Khumayni says that "one can choose between performing salatu 'z-zuhr or salatu 'l-jum`ah, but if one chooses the latter it is advisable (mustahab) to precautionarily perform salatu 'z-zuhr also."7 Although there are these differences in the opinions of these mujtahids, there is no clash that would, for example, prevent the follower (muqallid) of one of them participating in salatu 'l-jum`ah if it were established.
Secondly, it should be observed that the existence of differences in scientific opinions is not to be taken as a sign of a substantial defect in the quest for knowledge and a reason for abandoning it altogether; it is, rather, a sign that knowledge moves in progressive steps towards perfection.
Differences of opinions are to be found in all sciences, not just in fiqh. There may, for example, be more than one opinion about the therapy for a particular patient's disease, and all of these opinions may be superseded later on by the development of new methods of dealing with that disease. Thus these observations can be seen to be relevant not only to differences between the opinions of contemporary scientists but also to historical differences, and all these differences should be regarded as signs of the dynamism within a science and stages to be passed in its route to perfection.
It should be remembered that the mujtahid formulates his opinions after pushing his research and study as far as he can; that is all that is expected of him, for he is neither inerrant nor an `alim bi 'l-ghayb (knower of the unseen). The muqallid is enjoined to follow his opinions. So, even if the mujtahid's fatwa is not actually in agreement with Allah's real command, neither he will be punished on the Day of Judgement for having issued the fatwa, nor will his muqallid for having acted according to it, for both will have done what was commanded of them and what was humanly possible for them to do.
