However, the second meaning of Taqlid, used in religious terminology is completely different. It can be expressed in one sentence: “Following the specialists by non-specialists people in some matters.” That is, those who are not having the knowledge of religious problems, which require specialization and years of study they have to compulsorily follow the religious Mujtahid and act upon their rulings.
In this sense is the meaning applicable for Taqlid—that is the following of a learned person by a less learned person. It is the basis of human life in all the fields, be they agriculture, manufacturing or medicine.
If at any time this is taken out from human life, that is a patient does not visit a doctor, or people do not consult lawyers for legal advice, one does not consult the engineers and architects, one does not use the services of artisans, mechanics and experts of other fields, the social structure of the world would be endangered and every field will become extinct. The religious problems are not exempted from this system.
Without any doubts, in the principles of faith like Tawheed, Adl, Nubuwwat, Imamat and Qiyamat, everyone has to do proper research themselves and their justification is nothing difficult and complicated also. Every person can do this according to his or her understanding capacity.
However, for the Islamic practical laws: Worship acts, business transactions and politics like Prayer, fasting, holy war, penalties and punishments, relations and blood money marriage and divorce and thousands of other day-to-day matters. Not everyone can obtain the knowledge of all these laws individually, neither all can derive benefit from the sources of Islamic law, like the Holy Qur’an, traditions, Reason and Consensus.
Therefore people have no option but to follow the religious scholar for these problems. The scholars who have put in years of study and have gained deep knowledge of the book of Allah, the practice of the Prophet, and the sayings and writings of the Imams of Ahlul Bayt (a.s.). From this discussion we conclude that following a Mujtahid is not blind following without justification.
This Taqlid has the logical and reasonable proof as follows: The view of a scholar, a wise man and specialist and that also that it is harmless; it is usually nearest to the truth and generally it is not away from the truth.
