Conditions (Shurut) of Ijtihad
The mujtahid must be a Muslim and a competent person of sound mind who has attained a level of intellectual competence which enables him to form an independent judgment. In his capacity as a successor to the Prophet, the mujtahid performs a religious duty, and his verdict is a proof (hujjah) to those who follow him; he must therefore be a Muslim, and be knowledgeable in the various disciplines of religious learning. A person who fails to meet one or more of the requirements of ijtihad is disqualified and may not exercise ijtihad. The requirements which are discussed below contemplate ijtihad in its unrestricted form, often referred to as ijtihad fi'l-shar`, as opposed to the varieties of ijtihad that are confined to a particular school, or to particular issues within the confines of a given madhhab.
The earliest complete account of the qualifications of a mujtahid is given in Abu' Husayn al-Basri's (d.436/1044) al-Mu'tamad fi Usul al-Fiqh. The broad outline of al-Basri's exposition was later accepted, with minor changes, by al-Shirazi (d. 467/1083), al-Ghazali (d. 505/111 ) and al-Amidi (d. 632/1234). This does not mean that the requirements of ijtihad received no attention from the ulema who lived before al-Basri. But it was from then onwards that they were consistently adopted by the ulema of usul and became a standard feature of ijtihad.[30. Cf. Hallaq, The Gate, pp. 14-17.]
These requirements are as follows:
(a) Knowledge of Arabic to the extent that enables the scholar to enjoy a correct understanding of the Qur'an and the Sunnah. A complete command and erudition in Arabic is not a requirement, but the mujtahid must know the nuances of the language and be able to comprehend the sources accurately and deduce the ahkam from them with a high level of competence.[31. Ghazali, Mustasfa, II, 102; Abu Zahrah, Usul, p.302.] Al- Shatibi, however, lays greater emphasis on the knowledge of Arabic: a person who possesses only an average knowledge of Arabic cannot aim at the highest level of attainment in ijtihad. The language of the Qur'an and the Sunnah is the key to their comprehension and the ijtihad of anyone who is deficient in this respect is unacceptable. The same author adds: Since the opinion of the mujtahid is a proof (hujjah) for a layman, this degree of authority necessitates direct access to the sources and full competence in Arabic.[32. Shatibi, Muwafaqat, IV, 60.]
The mujtahid must also be knowledgeable in the Qur'an and the Sunnah, the Makki and the Madinese contents of the Qur'an, the occasions of its revelation (asbab al-nuzul) and the incidences of abrogation therein. More specifically, he must have a full grasp of the legal contents, or the ayat al-ahkam, but not necessarily of the narratives and parables of the Qur'an and its passages relating to the hereafter.[33. Ghazali, Mustasfa, II, 101.] According to some ulema, including al-Ghazali, Ibn al-Arabi, and Abu Bakr al-Raza, the legal ayat of the Qur'an which the mujtahid must know amount to about five hundred. Al-Shawkani, however, observes that a specification of this kind cannot be definitive. For a mujtahid may infer a legal rule from the narratives and parables that are found in the Qur'an. The knowledge of ayat al-ahkam includes knowledge of the related commentaries (tafasir) with special reference to the Sunnah and the views of the Companions. Al-Qurtubi's Tafsir al-Qurtubi, and the Ahkam al-Qur'an of Abu Bakr, 'Ali al-Jesses, are particularly recommended. [34. Shawkani, Irshad, pp. 250-51; Abu Zahrah, Usul, p.304; Zuhayr, Usul, IV, 226.]
Next, the mujtahid must possess an adequate knowledge of the Sunnah, especially that part of it which relates to the subject of his ijtihad. This is the view of those who admit the divisibility (tajzi'ah) of ijtihad (for which see below), but if ijtihad is deemed to be indivisible, then the mujtahid must be knowledgeable of the Sunnah as a whole, especially with reference to the ahkam texts, often referred to as ahadith al-ahkam. He must know the incidences of abrogation in the Sunnah, the general and the specific, ('amm and khass), the absolute and the qualified (mutlaq and muqayyad), and the reliability or otherwise of the narrators of Hadith. It is not necessary to commit to memory the ahadith al-ahkam or the names of their narrators, but he must know where to find the ahadith when he needs to refer to them, and be able to distinguish the reliable from the weak and the authentic from the spurious. [35. Shawkani, Irshad, p.251 ff; Abu Zahrah, Usul, p. 304.] Imam Ghazali points out that an adequate familiarity with the ahadith al-ahkam such as those found in Sunan Abi Dawud, Sunan al-Bayhaqi, or the Musnad of Ibn Hanbal would suffice. According to another view, which is attributed to Ahmad b. Hanbal, the ahadith al-ahkam are likely to number in the region of 1200. [36. Ghazali, Mustasfa, II, 101; Shawkani, Irshad, p. 251.]
The mujtahid must also know the substance of the furu`works and the points on which there is an ijma'. He should be able to verify the consensus of the Companions, the Successors, and the leading Imams and mujtahidun of the past so that he is guarded against the possibility of issuing an opinion contrary to such an ijma`. It would be rare, al-Shawkani observes, for anyone who has attained the rank of a mujtahid not to be aware of the issues on which there is a conclusive ijma`. By implication, the mujtahid must also be aware of the opposing views, as it is said, 'the most learned of people is also one
who is most knowledgeable of the differences among people'.[37. Shawkani, Irshad, p. 251; Ghazali, Mustasfa, II, 101; Abu
Zahrah, Usul, p. 305.]
In their expositions of the qualifications of a mujtahid, the ulema of usul place a special emphasis on the knowledge of qiyas. The Qur'an and the Sunnah, on the whole, do not completely specify the law as it might be stated in a juristic manual, but contact general rulings and indications as in the causes of such rulings. The mujtahid is thus enabled to have recourse to analogical deduction in order to discover the ruling for an unprecedented case. An adequate knowledge of the rules and procedures of qiyas is thus essential for the mujtahid. Imam Shafi`i has gone so far as to equate ijtihad with qiyas. Analogy, in other words, is the main bastion of ijtihad, even if the two are not identical. Al-Ghazali has observed that notwithstanding the claim by some ulema that qiyas and ijtihad are identical and coextensive, ijtihad is wider than qiyas as it comprises methods of reasoning other than analogy.[38. Ghazali, Mustasfa, II, 54; Shawkani, Irshad, p. 252; Abu Zahrah, Usul, p. 306.]
Furthermore, the mujtahid should know the objectives (maqasid) of the Shari'ah, which consist of the masalih (considerations of public interest). The most important masalih are those which the Lawgiver has Himself identified and which must be given priority over others. Thus the protection of the `Five Principles', namely of his, religion, intellect, lineage and property, are the recognised objectives of the Lawgiver. These are the essentials (daruriyyat) of the masalih and as such they are distinguished from the complementary (hajiyyat) and the embellishments (tahsiniyyat). The mujtahid must also know the general maxims of fiqh such as the removal of hardship (raf`al-haraj), that certainty must prevail over doubt, and other such principles which are designed to prevent rigidity in the ahkam. He must be able to distinguish the genuine masalih from those which might be inspired by whimsical desires, and be able to achieve a correct balance between values.[39. Shawkani, Irshad, p. 252; Abu Zahrah, Usul, p.307; Badran, Usul, p. 208.]
Al-Shatibi summarises all the foregoing requirements of ijtihad under two main headings, one of which is the adequate grasp of the objectives of the Shari'ah, while the other is the knowledge of the sources and the methods of deduction. The first of these is fundamental, and the second serves as an instrument of achieving the first.[40. Shatibi, Muwafaqat, IV, 56; Abu Zahrah, Usul, p. 307.]
It is further suggested in this connection that the mujtahid must be capable of distinguishing strength and weakness in reasoning and evidence. This requirement has prompted some ulema to say that the mujtahid should have a knowledge of logic (mantiq). But this is not strictly a requirement. For logic as a discipline had not even developed during the time of the Companions, but this did not detract from their ability to practice ijtihad.[41. Abu Zahrah, Usul, pp. 308-309; Ghazali, (Mustasfa, II, 103), considers a knowledge of Arabic, Hadith and usul al-fiqh to be essential to ijtihad. However the requirement concerning the knowledge of Usul would seem to be repetitive in view of the separate conditions that the mujtahid must fulfill, such as the knowledge of qiyas and other such requirements, which fall under the subject of Usul.]
And finally, the mujtahid must be an upright (`adil) person who refrains from committing sins and whose judgement the people can trust. His sincerity must be beyond question and untainted with selfseeking interests. For ijtihad is a sacred trust, and anyone who is tainted with heresy and selfindulgence is unworthy of it.[42. Ghazali, Mustasfa, II, 101; Shawkani, Irshad, p. 252.] These are the conditions of independent ijtihad, but a mujtahid on particular issues need only know all the relevant information concerning those issues and may, at least according to those who admit the `divisibility' of ijtihad, practice ijtihad in respect of them. His lack of knowledge in matters unrelated to the issues concerned does not prejudice his competence for ijtihad.[43. Ghazali, Mustafa, II, 102-103; Kassab, Adwa', p.38.]
Some observers have suggested that the practice of ijtihad was abandoned partly because the qualifications required for its practice were made 'so immaculate and rigorous and were set so high that they were humanly impossible of fulfilment'.[44. Cf. Fazlur Rahman, Islam, p. 78.] This is, however, an implausible supposition which has been advanced mainly by the proponents of taqlid with a view to discouraging the practice of ijtihad. As for the actual conditions, Abdur Rahim (with many others) has aptly observed that `the qualifications required of a mujtahid would seem to be extremely moderate, and there can be no warrant for supposing that men of the present day are unfitted to acquire such qualifications'. [45. Abdur Rahim, Jurisprudence, p. 174.] There is little evidence to prove that fulfilling the necessary conditions of ijtihad was beyond the reach of the ulema of later periods. on the contrary, as one observer has pointed out, `the total knowledge required on the part of the jurist enabled many to undertake ijtihad in one area of the law or another'. [46. Hallaq, The Gate, p. 14.] Their task was further facilitated by the legal theory, in particular the Hadith which absolved the mujtahid who committed an error from the charge of sin and even entitled him to a spiritual reward. Furthermore, the recognition in the legal theory of the divisibility of ijtihad, as we shall presently discuss, enabled the specialist in particular areas of the Shari`ah to practice ijtihad even if he was not equally knowledgeable in all of its other disciplines.
