In this matter to reach the destination they will be forced to seek the guidance of people who reside in that area. Or for example an environmentalist, who becomes ill, is forced to go to a physician, although this person knows about environment he does not know about diseases and their cure. There is no way except that he should go to a doctor and take the medicine or injection.

He should not grumble and follow the instructions carefully and he does not ask why the doctor has prescribed such and such medicine. Keeping these two examples in mind, it becomes clear that even if the person is an expert in his own field he should follow the rulings of a Mujtahid. The reason is that a Faqih (jurisprudent) is expert in his field. He is expert in many sciences, which are his basis in jurisprudence.

(Morphology, Grammar, Arabic literature, logic, exegesis, Rijal -biography of the traditionists-, sources, traditions, Principles of jurisprudence, interlocution etc). By seeing a small book called Tauzihul Masael you may not know that it is the result of life long toil of a Mujtahid. He has written it only after putting blood of his heart in it and only then he has presented it to the common people. Ijtihad is not easy.

Ijtihad means to acquire the knowledge of all the Islamic laws, which affect a person or the whole society, and in all spheres of life. Shaykh Murtaza Ansari, who was a great Mujtahid himself and the proud son of Islamic Jurisprudence who himself took lot of trouble and hard work to become a Mujtahid says in his book Rasael : Allah has given us the opportunity of Ijtihad , which is tougher than continuous Jihad and much more painful.

It is necessary to say that Taqlid of a Mujtahid is not in articles of faith but it is related to the practical law. In other words it is necessary to follow a Mujtahid in the rules, regulations and branches of religion and not in the roots of religion. It is so because Allah, the most High and the recognition of the Holy Prophets are the basis of religion, and to know them through logic and arguments is necessary.

So that after accepting the roots of religion with logic and arguments, in the branches of religion (whose religious source like the glorious Quran and traditions and to understand the other proofs, it is necessary to know different branches of knowledge and to be expert in it) we must refer to Mujtahids who are expert and authority in this field.
