Ijtihad

Allah commands you to seek knowledge

“My Lord, increase me in knowledge” (Surah Ta-Ha 20:114). DeenUp turns that command into a daily habit — a swipeable feed of bite-sized, scholar-approved Islamic lessons, quick quizzes, and daily streaks.

What is Ijtihad?

Ijtihad comes from the Arabic root j-h-d, meaning "to strive," "to exert effort," or "to struggle earnestly" — the same root that gives us jihad in its broader sense of striving. In Islamic legal theory, ijtihad refers to the rigorous, disciplined intellectual effort a qualified jurist (mujtahid) undertakes to derive a ruling on a matter not explicitly and unambiguously settled by the Qur'an or Sunnah, using recognized tools such as qiyas (analogy), consideration of the objectives of the Sharia, and other established methods.

Becoming a mujtahid is not a casual undertaking. Classical scholars set demanding conditions: complete command of the Arabic language and its nuances, comprehensive knowledge of the relevant Qur'anic verses and hadith along with their contexts and chains of transmission, awareness of matters already settled by scholarly consensus (ijma) so as not to contradict them, and deep training in usul al-fiqh, the methodology governing how rulings are properly derived. Only someone meeting this bar is considered qualified to exercise independent ijtihad rather than simply repeating existing opinions.

Ijtihad stands in direct contrast to taqlid — the practice of following an established ruling or a qualified scholar's verdict without independently re-deriving it oneself. The founders of the four Sunni madhabs, Abu Hanifah, Malik ibn Anas, al-Shafi'i, and Ahmad ibn Hanbal, were themselves master mujtahids, and their schools developed as later scholars organized, refined, and applied their foundational methodologies to new questions across generations.

A long-running scholarly debate concerns whether the "gates of ijtihad" have closed. Some later scholars argued that after the formative centuries, no one could realistically meet the full qualifications of a mujtahid, encouraging reliance on the accumulated rulings of the established madhabs instead. Others firmly reject this view, holding that ijtihad remains open to any scholar who genuinely satisfies its conditions, and pointing to ongoing ijtihad on modern issues — from bioethics to digital finance — as evidence that the door was never truly shut.

In practice, ijtihad allows Islamic law to remain a living, responsive tradition capable of addressing genuinely new circumstances, while still remaining firmly tethered to the Qur'an and Sunnah rather than drifting into unmoored personal opinion.

Examples of Ijtihad

• Rulings on modern medical procedures: Contemporary scholars exercise ijtihad to address issues like organ transplantation or genetic testing, which the classical texts do not explicitly mention.
• Islamic finance innovations: Jurists use ijtihad to evaluate whether new financial products comply with Sharia principles regarding riba and speculative risk.
• Umar ibn al-Khattab's rulings: The second caliph is often cited for his independent reasoning on matters like suspending the hadd punishment for theft during famine.
• Digital and cryptocurrency questions: Modern fiqh councils apply ijtihad to determine the permissibility of new forms of digital currency and online transactions.
