Abrogation (Naskh) in Divine Law

One of Pfander's recurring arguments against Islam in Mizan al-Haqq was that the Islamic doctrine of abrogation (naskh), by which later Quranic verses can abrogate earlier ones, undermines the reliability and coherence of divine revelation. If Allah reveals a command and then later reveals a different command on the same matter, how can we trust the stability and consistency of divine guidance? Does not abrogation imply either that Allah changed his mind (implying imperfection) or that the earlier revelation was defective and needed correction? Pfander presented this as a unique vulnerability of Islamic theology, suggesting that the Christian canon, as a completed and internally consistent whole, was superior to a Quran that apparently revised itself over time.

Al-Kairanawi's response to this argument is both defensive and offensive. Defensively, he explains the Islamic understanding of naskh: that abrogation does not imply error or change of mind on Allah's part but reflects the pedagogical and developmental nature of divine guidance. Allah, in His wisdom, reveals guidance appropriate to the situation and capacity of the community at each stage of their development. The early Muslims, like any community learning a new way of life, required a gradual process of instruction in which foundational principles were established before more demanding obligations were imposed. The abrogation of earlier rulings by later ones follows the same logic as a teacher who assigns elementary exercises before advanced ones: the earlier exercises are not wrong but are superseded by more mature requirements. This understanding is entirely consistent with divine perfection and foreknowledge.

But al-Kairanawi's most effective response is to point out that the Christian scriptures themselves exhibit abrogation in a far more radical form than anything found in the Quran. The relationship between the Old Testament and the New Testament is, in standard Christian theology, precisely one of abrogation: the ceremonial and ritual law of Moses, including the dietary restrictions, the animal sacrifices, the Sabbath regulations, and the requirement of circumcision, is explicitly set aside by the New Testament. Christians do not observe the Mosaic law in its fullness, and the New Testament explicitly argues that this law was provisional and has been superseded by the covenant of grace established through Christ. If abrogation is a theological incoherence, it is an incoherence in Christianity no less than in Islam; if it is a legitimate mode of divine communication, as Christians must believe given their own relationship to the Mosaic law, then the Islamic doctrine of naskh is equally legitimate.

This argument illustrates a recurring methodological feature of Izhar al-Haqq: al-Kairanawi frequently demonstrates that the principles that Christian missionaries invoke against Islam apply with equal or greater force against Christian doctrine itself. This creates an asymmetric situation for the missionary: either the principle is valid (in which case it damages Christianity as much as Islam) or it is not valid (in which case the original attack on Islam fails). Al-Kairanawi's Agra debate strategy of using Christian internal inconsistencies against Christian polemicists is systematically elaborated in the Izhar al-Haqq, making it not merely a defensive work but an active demonstration of the relative standing of the two traditions when evaluated by consistent rational and historical principles.
