Large language models (LLMs) demonstrate significant limitations in their ability to provide reliable religious guidance on Islamic law, according to a new study. The study, titled 'IslamicLegalBench' and published on arXiv, evaluated nine state-of-the-art models, including GPT, Claude, and DeepSeek, across seven schools of Islamic jurisprudence spanning 1,200 years of legal traditions (arXiv CS.AI). The research highlights critical gaps in AI tools that are increasingly relied upon by millions of Muslims for spiritual advice.
The best-performing model achieved only 68% correctness, accompanied by 21% hallucination, according to the study. Several models fell below 35% correctness while exceeding 55% hallucination. Few-shot prompting offered minimal improvements, enhancing only two of nine models by more than one percent (arXiv CS.AI).
Researchers assessed the models' performance on tasks ranging from simple queries to complex legal reasoning. Moderate-complexity tasks requiring precise knowledge showed the highest error rates, according to the study. High-complexity tasks displayed apparent competence through semantic reasoning, but the study found this to be misleading (arXiv CS.AI).
False premise detection revealed a tendency toward risky sycophancy, with six of the nine models accepting misleading assumptions at rates above 40%, according to the research. The authors of the study, Ezieddin Elmahjub, Junaid Qadir, Abdullah Mushtaq, Rafay Naeem, Ibrahim Ghaznavi, and Waleed Iqbal, found that prompt-based methods could not compensate for missing foundational knowledge (arXiv CS.AI).
The manuscript was submitted for review to Artificial Intelligence & Law on February 2, 2026, and published on arXiv on February 26, 2026.
Why It Matters
This study raises serious concerns about the reliability of AI in providing religious guidance. With millions of Muslims turning to AI for spiritual advice, the inaccuracies and hallucinations exhibited by LLMs could have significant ethical and religious implications. The 'IslamicLegalBench' study sets a new standard for evaluating AI in religious contexts, highlighting the need for more robust and accurate AI systems.
The Bottom Line
LLMs are not yet reliable sources for Islamic legal guidance, and their use in this context carries significant risks due to inaccuracies and potential for misleading information.
