Through this maxim, the Sharia recognizes people’s varying norms, customs and traditions, and preserves the cultural identities of diverse nations. This also applies to people of different times, accommodating the changes that humans of different generations are bound to experience.
While ijtihâd is always necessary in all fields to correct our understanding, the following are matters that are not subject to change, whether due to changes in customs, world conditions, technological advancements, or any circumstantial variables:
· All matters of creed. These are not subject to new ijtihâd in the sense of forming new positions compatible with new realities, but we do need ijtihâd to correct our own understanding of some of these concepts. For example, the misunderstanding of qadr (predestination) and zuhd (asceticism, or renunciation of worldly matters) has been detrimental to the wellbeing of the Ummah and can impede any prospects for progress. Simply put, we need to reset our collective understanding of these concepts – back to that of the Messenger (SA) and his Companions (RAHUM), whose teachings and lives will always be the brightest beacon of light and the unfailing benchmark.
· The pillars of Islam.
· Rulings in the sphere of worship whose causes we do not understand, such as the times of the different prayers and their composition, the rituals of Hajj and fasting, and the like.
· Quantified injunctions of the Sharia (muqaddarât) that were fixed by the text of revelation, such as expiations (kaffârât), duration of the waiting period (‘iddah), and entitlements to inheritance.
· Matters about which there is an explicit text with a definitive implication, a certain transmission, and their effective cause is still operative.
· Matters on which there is a clear and genuine consensus that is not based on circumstantial variables such as in cases where the common interest (or weighing harm vs. benefit) is the deciding factor. · Basic rulings of morality and those that define the Islamic value system, such as the prohibition of arrogance, prejudice, murder, fornication, usury, gossip, slander, and so on; the obligation of mutual agreement in contracts; and the protection of basic human rights such as the sanctity of life, property, and reputation. Regarding these issues, change may only be related to the means of preserving those values and rights.
After excluding those spheres, it seems that the renewal of ijtihâd is most needed in the areas of governance, public policy, international relations, financial transactions, employment, corporate ethics, admissible proofs, judiciary proceedings, and to some extent interpersonal relations and relations with people of different theological orientations and religious affiliations.
In all these areas, ijtihâd-based renewal is necessary to maintain the vitality and relevance of the laws and Divine teachings. A seasoned Azhari scholar of the fourteenth century, Shaykh ‘Abdul-Wahhâb Khallâf, traces the stagnation in ijtihâd to four reasons:
1- Political division and infighting within the Muslim state, which derailed scholars in all fields from developing their respective disciplines
2- Madh-hab-based partisanship, which kept many scholars preoccupied with a keen interest in supporting their own madh-hab and proving it correct, precluding an impartial inquiry into the body of evidences, particularly the Qur’an and the Sunnah
