The science of 'usûlu 'l-fiqh (Principles of Jurisprudence)...
The science of 'usûlu 'l-fiqh (Principles of Jurisprudence), Arabic grammar and literature, as well as familiarity with the views of the Sunni jurists who were contemporaries of the Imams play an important role in the understanding of the hadith texts. c. Third: Soundness of his view in deriving the rules from the sources.
And the method of getting acquainted with those in whom the status of a'lam is confined to having scholarly discussions with them or to referring to their books or to the transcripts of their lectures on Jurisprudence and the Principles of Jurisprudence. If a person cannot know the ahlul khibra by himself, he can come to know them through the religious scholars and others whom he trusts.
The geographical distance should not be a barrier to establishing communication with them in this era where many fast means of communication are easily available. Question: Sometimes the heart feels at ease in regard to a particular mujtahid. Is this feeling sufficient to do his taqlid if the ahlul khibra have difference of opinion in determining the a'lam?
Answer: If the ahlul khibra have difference of opinion in determining the a'lam, one must follow the view of those who are more qualified and capable among the ahlul khibra. This is the norm in dealing with all cases where the experts have difference of opinion.
Question: If the ahlul khibra have difference of opinion in determining the a'lam mujtahid or just say that following any one from the given number of mujtahids is sufficient, can a person apply the fatwa of one mujtahid in one issue and another mujtahid in another until it becomes clear for him who is the a'lam? Answer: This question has three parts: d.
First: That some ahlul khibra announce that "it is sufficient to follow one specific mujtahid or of a group of mujtahids." This has no religious value at all. e. Second: That the ahlul khibra announce that two or more mujtahids are equal in knowledge and piety (in the sense of being careful in deriving the laws [from their sources]), then a lay person has the option of acting according to the views of any one of the mujtahids in all the issues.
However, as a matter of precaution (ihtiyat) in some issues, if possible, one could act in such a manner as to fulfill the requirements of both views; for example, in the case of praying concessionary qasr and full (tamam) prayers. [That is, praying the same prayer in qasr as well as in tamam forms.] f.
