Ijtihad means full effort: Ijtihad comes from a word meaning effort and exertion. It is the process by which a qualified jurist (Mujtahid) uses his full knowledge and the complete toolkit of Usul al-Fiqh to derive a ruling from the Quran, the Sunna, 'Aql, and Ijma' for a specific question.
It is not personal opinion: Ijtihad is not making up rulings from one's own feelings or culture. That would be Ra'y (personal opinion) or Bid'a (innovation), which the Imams (as) condemned. It is not Qiyas, and not Istihsan either. Ijtihad is the disciplined use of a strict method — checking narrators, understanding the words, weighing the evidence, and resolving conflicts step by step.
It takes decades to learn: A Mujtahid must master Arabic at the highest level, the Quran and its interpretation, the sciences of Hadith and Ilm al-Rijal, all of Usul al-Fiqh, the whole body of Fiqh, and logic. In the traditional seminary (Hawza), this usually takes 20 to 35 years of full-time study.
The result is probable, not certain: The Mujtahid does not claim to know Allah's real ruling with certainty. He claims to have applied the best method to the best evidence and reached the most defensible conclusion. If he is wrong, he is Ma'dhur (excused before Allah), because his method was correct.
Example
A heart patient does not operate on himself after reading one medical article. He goes to a surgeon who studied medicine for twenty years. In the same way, deriving a ruling is specialist work — it belongs to the one who spent decades learning the tools, not to anyone with an opinion.
