The intersection of Arabic linguistic complexity and specialized reasoning presents a key challenge for Islamic question-answering systems, particularly in the under-addressed area of inheritance law.This paper presents our methodology for the QIAS2025 shared task, assessing LLM capabilities in Islamic knowledge through two subtasks: Inheritance Reasoning (ʿilm al-mawārīth) and General Islamic Assessment.A zero-shot, prompt-based approach with DeepSeek-R1 (deepseek-reasoner) addresses the former, while a three-stage RAG pipeline handles the latter.Our approaches achieved competitive results, with an accuracy of 0.704 for inheritance reasoning (10th place/15 teams) and 0.9272 for general Islamic assessment (2nd place/10 teams), demonstrating the efficacy of tailored model strategies for religious QA.These insights pave the way for more culturally and linguistically adaptive AI systems in Islamic scholarly applications.
